I want a full-featured WhatsApp chatbot that helps patients quickly find and book appointments at nearby hospitals. This can be a WhatsApp bot or android application. Anything you can generate is ok. The flow should start by asking for the user’s location (either GPS pin or typed suburb), then list hospitals that match the services they need—maternity, theatre, GP, plus accident & emergency, casualty, ambulance, medical aid desks, laboratory, diagnostic imaging, dental, optometry, physiotherapy, dermatology, and gynaecological care. After the user selects a facility, the bot must: • Confirm available time slots and complete the booking in-chat. • Store the appointment date, automatically send a daily or weekly countdown, and push any special notes I add (e.g., ...

The goal is to create an external overlay for Minecraft Java 1.8.9(would be awesome if it supports 1.8.9 as well as the latest version but thats not a priority, 1.8 is) that runs on Windows and remains completely invisible to Discord screen-share and Windows Game Bar recordings while adding no perceptible latency. Because it lives outside of the game’s memory space, it must never trip basic anti-cheat checks or appear in captured footage, yet still render in real time on my own screen. Core functionality • Stream-proof, zero-latency overlay (top priority) • Visual mods (i'll specify once we contact) • Item and chest/storage tracking • Minimalist, key-toggleable GUI that blends with the vanilla look Technical notes – External overlay approac...

I’m ready to bring my e-commerce concept to life with a dedicated Android app. The core idea is simple: a smooth, intuitive shopping experience that lets customers browse, buy, and track orders without friction. I already have the product catalogue and brand assets prepared; what I need is an experienced Android developer who can translate that vision int

I’m looking for a developer who can turn my customer-support workflows into a single, friendly WhatsApp bot. The bot’s core purpose is customer support, and it must be able to: • Create bookings • Answer FAQs • Check flight status • Confirm whether luggage has been paid I will supply the content for our standard FAQs and the booking, flight-status, and luggage endpoints (or data extracts) we already use. You will connect these to the WhatsApp Business API, design clear conversational flows, and return a deployable, well-documented solution that my team can maintain. Key expectations • Clean code in a language or framework you are comfortable with (Node.js, Python, Java are all acceptable). • Error handling, user-friendly prompts, and f...

All of my WhatsApp conversations—both personal and group—were accidentally wiped from my Android handset, and I never enabled either Google Drive or local backups. The phone is still in my possession and fully functional; I simply need every deleted message, media file, timestamp, and attachment brought back in a readable format or restored directly into WhatsApp. I’m aware this requires deep-level Android and WhatsApp data extraction, so experience with mobile forensics tools such as Cellebrite, Magnet, or equivalent ADB-based solutions is essential. Root access can be granted if necessary. Please outline: • the technique you intend to use (logical vs. physical acquisition, encrypted database decryption, etc.) • expected recovery success rate for chats with...

I have a completed dev build created from Claude as drop in modules. My goal is to add an on-page interactive chatbot to my custom HTML/CSS site that focuses entirely on lead generation. The bot should welcome visitors, guide them through a conversational flow, and hand me qualified prospects in real time. Data to capture • Name and email address • Phone number and company name • Product interest and budget I’m open to your preferred stack—Dialogflow, Botpress, Microsoft Bot Framework, or a lightweight vanilla-JS solution—as long as the final script drops cleanly into my existing codebase and works across modern browsers. Key expectations • Conversational logic that feels human, not scripted • Validation on required fields and gr...

I am ready to automate my entire customer-service workflow with an AI-powered chatbot that can handle Answering FAQs, Ticket routing, and Live chat support. The bot must work seamlessly across my website, social media pages, and popular messaging apps so customers receive the same fast, friendly help wherever they reach out. What I need • Conversational flows planned around our current FAQ and support scripts, including smart escalation to human agents for complex cases. • Integration with the site (JavaScript snippet or API), Facebook/Instagram/Twitter social channels, plus messaging platforms such as WhatsApp, Telegram, or Messenger. • Automated ticket routing into our existing help-desk system, tagging each request with intent, urgency, and customer details. &bul...

I’m running an Onn Android TV box and want the device to look at a USB drive the moment it powers up. Instead of jumping straight into the stock interface, it should display a simple launcher-selection screen: two large, side-by-side icons—one for the factory launcher that ships with the box and one for my own launcher (already supplied as an APK). Tapping either icon should immediately take me into the chosen environment with no extra prompts. What I need from you is a ready-to-flash image that lives on the USB stick, autoloads at boot, shows the two icons exactly as described, and hands off to the selected launcher cleanly. Please bundle my APK, make sure the default launcher remains untouched, and keep everything seamless so I can plug the drive in, power on, and choose. D...

I’m building an Android-only “view-for-view” platform where members earn views for their own YouTube videos by watching those of others. The core build I need from you is the initial MVP that proves the loop works smoothly on mobile. Scope of the first release • Secure user registration and login (email or Google sign-in). • A simple feed that serves YouTube videos and silently tracks watch time.

I need a full-featured, web-based e-commerce application. At minimum, it must include: • User authentication • Shopping cart functionality • Payment gateway integration Beyond these essentials, I’m open to the stack you feel is best—whether that’s Java with Spring, a Python/Django setup, a C++ back end with React on the front, or another modern solution you can justify. What matters most is clean, well-documented, scalable code that I can maintain long-term. Here’s how we’ll work: 1.

I’m building an Android application that lets customers order food and beverages from multiple independent vendors in a single, streamlined marketplace. Shoppers will sign up or log in with their phone number and a one-time password; I’d like that flow to be quick and secure, with proper verification handling on the backend. Core experience • Menu browsing by vendor, add-to-cart, and a smooth checkout that supports in-app payments (credit/debit cards, UPI, wallets—whichever gateway you feel integrates cleanly with Android). • Real-time order tracking so a customer can follow progress from “accepted” through preparation to delivery, ideally using live status updates or a lightweight map view if feasible. • Vendor ratings and written review...

I'm looking for an experienced Flutter developer to update my existing Flutter application to meet the latest Google Play requirements. Google Play has notified me that the app targets an outdated Android API level and must be updated before August 31, 2026. Scope of Work: Update the Flutter project to support the latest Target SDK (API Level 36 or the current Google Play requirement). Update Flutter dependencies/packages if required.

My Android app is feature-complete and ready for a round of focused functional testing before I push it to production. I need you to install the current APK on a variety of real devices or well-configured emulators, walk through every user flow, and uncover anything that blocks, crashes, or behaves unexpectedly. The priority for this engagement is functionality; once that’s solid we may explore user-interface or performance audits in a follow-up sprint. I’m looking for clear, reproducible bug reports that include: device/OS details, steps to reproduce, expected vs. actual results, screenshots or screen recordings, and a quick severity rating. Feel free to use the usual Android toolset—ADB, Logcat, Crashlytics, Espresso scripts, or whatever helps you surface issues quickl...

I’m adding a security layer to my OTT streaming app: it must refuse to install or launch anywhere that isn’t a genuine, physical phone or tablet. The objective is simple—stop screen-capture attempts by ensuring the app shuts down the moment it detects Bluestacks, NoxPlayer, the Android Studio emulator, Xcode Simulator, Genymotion or any other virtual environment. Your task is to weave reliable emulator/simulator detection into both codebases (Android – Kotlin/Java, iOS – Swift/Obj-C). When a non-physical device is identified, the app should exit gracefully after showing a brief message; nothing should continue to run in the background. Deliverables • Integrated detection logic for Android and iOS, committed to the existing repositories I’ll sh...

My Java / Spring Boot backend needs immediate attention. The first priority is to hunt down and resolve several stubborn bugs that are breaking existing functionality, then improve overall performance so response times stay snappy even under load. Once stability is restored, I want to push forward with three concrete additions built on the same stack (Java 17, Spring Boot, Spring Data JPA, Hibernate, MySQL / MariaDB, REST and Git): • Clean CRUD endpoints for new domain entities • Seamless third-party API integrations (JSON / REST) • Robust user authentication and authorization I already have the project in a private Git repo and can grant access as soon as we agree on scope. Clear, well-structured code, meaningful commits and open communication are essential. Evenin...

Hi, I’m looking for a highly experienced software engineer to collaborate with me on the project. The work involves creating and repairing advanced software-engineering tasks used to evaluate and train AI coding agents. Each task is based on a real GitHub repository, pull request, or commit and must include accurate instructions, strong regression tests, a correct oracle solution, reproducible Docker configuration, and complete metadata. I need someone who is strong in software architecture, Git, Docker, CI/CD, automated testing, and debugging across different programming languages. Experience with AI evaluation, coding agents, benchmark development, or adversarial test design would be especially valuable. The engineer must be able to identify subtle failures—such as mismatc...

I want to launch a clean, fast-loading blog built with Java on the back end and polished with solid CSS on the front. The core requirement is a reliable search feature so readers can find posts quickly. I am not interested in WordPress or Joomla; instead, I’d like the site powered by a Java-based CMS or a custom Java solution that still gives me an intuitive admin area for writing, editing, and scheduling articles. Here’s what I need you to deliver: • A fully responsive blog interface styled with modern, maintainable CSS • Java server-side code (Spring Boot, Servlets, or your preferred Java framework) that handles post management and integrates the search functionality • Simple dashboard where I can create categories/tags, publish content, and review basic...

I’m putting together an Aviator-style mobile game built with Flutter and need a developer who can take it from first commit to a polished Android release. The gameplay itself is already scoped; what I’m missing is the full app wrapper and the supporting admin pieces so I can manage players and scores without touching the codebase each time. Here’s the core I need you to implement and wire up: • User registration and secure login (email or phone, whatever is quickest to verify) • A real-time leaderboard that updates after every round and persists between sessions On the admin side I’ll need a small panel or secured route inside the same Flutter project where I can: – View, filter, and ban users – Reset or edit scores if needed &ndas...

I have a beginner-level Java console assignment that I need completed quickly and cleanly. The task must run entirely from the command line, use only standard Java libraries, and follow clear, easy-to-read coding conventions so I can review and learn from the solution later. Here is what I need from you: • Fully working .java source files that compile and execute without modification. • In-line comments explaining the logic at each major step. • A short README (plain text is fine) with compile/run instructions and a brief overview of your approach. • Sample console input and the exact output your program produces, so I can verify the results on my machine. The assignment is small and should be perfect for someone comfortable with loops, conditionals, basic cla...

The Blockchain-Based KYC Model for Credit Allocation in Banking is a secure and decentralized system that simplifies the Know Your Customer (KYC) verification process while improving the efficiency of loan approvals. Instead of storing customer data in a centralized database, KYC information is securely stored and shared using blockchain technology, making it tamper-proof, transparent, and easily accessible to authorized banks. The system uses smart contracts to automate KYC verification and loan eligibility checks. Once a customer's identity is verified, the verified KYC data can be reused across multiple banks, reducing duplicate verification, saving time, and lowering operational costs. A credit assessment module analyzes the customer's financial information and credit histor...

I’m building a green-field SaaS startup and need a set of AI agents that will sit at the heart of the platform. Each agent must seamlessly blend Natural Language Processing, Machine Learning and Predictive Analytics so it can absorb both structured and unstructured data, learn from every interaction and surface actionable, forward-looking insights for our users in real time. What I need you to do • Design the overall agent architecture as modular micro-services that we can scale independently. • Implement and train the first production-ready models on the sample data I provide, then document how my team can retrain them as fresh data arrives. • Expose the agents through a clean REST or GraphQL API and, where it makes sense, a conversational chat interface. &bu...

I’m building a focused productivity app for Android that helps users organise their tasks quickly and stay on track throughout the day. The core of the product is a robust task-management module: users need to be able to create, edit, prioritise, and mark tasks complete with a fluid, modern Material 3 interface. Smooth performance on current Android versions is essential. If you have experience integrating extras such as calendar hooks or note snippets, let me know—I may extend the scope once the base release is stable, but for now I’m concentrating on best-in-class task handling. Deliverables • Fully-functioning Android (Kotlin or Java) app with task-management features described above • Clean, well-commented source code ready for hand-off in Git reposito...

Experience with Python, JavaScript, TypeScript, Java, C#, or similar languages is preferred. You should be able to: Understand coding requirements quickly. Evaluate correctness, pe...

I need an experienced developer to turn my concept, “Makumana MJ”, into a polished Android utility app. The core idea is to offer users a practical tool they can rely on daily, so I am looking for clean, efficient code, a lightweight footprint, and an interface that feels intuitive right out of the gate. Here’s what I will be expecting from you: • A fully-functional Android application (compatible back to Android 8.0) • Source code with clear, maintainable comments • A brief setup guide so I can compile and run the project locally • An upload-ready Play Store bundle and signed APK Quality assurance is important to me, so please include basic unit tests and a short test plan covering the main user flows. If you have shipped utility apps before,...

I need a quick, clean removal of several unwanted items from my system. Specifically, the job is to: • Uninstall all specified extensions from Google Chrome. • Fully remove the related desktop or background applications tied to those extensions. Please ensure there are no traces left behind—no residual files, registry entries, or hidden folders. I’m on macOS (Ventura) and will supply a list of the exact extensions and apps once we start. Screenshots confirming each removal and a brief summary of the steps you took will serve as my acceptance criteria. Remote work over Zoom or AnyDesk is fine as long as the job is completed in one session.

I’m building an Android-only e-commerce app and need a clean, well-documented backend API to power it. The immediate scope centres on two pillars: secure user authentication and a fully working payment gateway. For authentication I want a modern, token-based flow with encrypted password storage, password reset and token refresh endpoints. OAuth2 or JWT is fine as long as the implementation follows OWASP recommendations and is easy to consume from an Android client (Retrofit will be used on the app side). On payments, the API must connect to a mainstream gateway—Stripe, PayPal or a similar provider—run in sandbox first, then be production-ready. Endpoints should let the app create an order, start a transaction, receive gateway callbacks/webhooks and return a clear succes...

My current C/C++ codebase is functionally solid but far too heavy on RAM. I want it slimmed down without sacrificing stability, so your primary mission is to diagnose and trim memory consumption across the project. Here’s the picture: • The focus is squarely on C and C++ sources. • I need concrete, measurable memory savings—ideally demonstrated through before-and-after profiling runs. • Speed and readability improvements are welcome side-effects, but memory is the KPI that matters. How we’ll work: 1. You begin with a deep dive using the tools you trust—Valgrind, AddressSanitizer, massif-visualizer, perf, or similar—to chart current heap/stack behaviour. 2. From those findings you’ll redesign data structures, apply smarter algorithm...

Project Brief: Secure PDF Ebook Viewer App (iOS + Android) Overview We need a mobile app (iOS + Android) that lets authenticated users view PDF ebooks in-app only. Users should not be able to download, export, print, or easily screenshot/screen-record the content. The goal is strong deterrence against content leakage — not absolute prevention, which no platform can guarantee (especially iOS). Recommended Stack Framework: Flutter (single codebase for iOS + Android), unless the developer has a strong reason to recommend native (Swift/Kotlin) instead. PDF rendering: In-app rendering only (e.g. Syncfusion Flutter PDF Viewer, or equivalent) — no native "open in other app" or file export paths. Backend: Required. PDFs must be served via authenticated, short-lived signed U...

We already have an Android application developed for Baljwan Medicines that is primarily used by sales representatives to manage clients and offer promotional schemes through a Wheel Game module.
