I have an Android app that currently uses the Yandex Mobile Ads SDK. I need every Yandex placement removed and replaced with Appodeal, integrating banner, interstitial, and rewarded-video formats. The project is native Android (Android Studio, Gradle), written in Java/Kotlin. I will supply the full source code plus my Appodeal app key; you will: • strip out all Yandex SDK calls, dependencies, and Gradle artifacts • add the latest Appodeal SDK, configure banner, interstitial, and rewarded-video units, and ensure they respect user privacy settings (GDPR/Google Play policies) • test the build on several physical devices and common emulators to confirm ads load, display, and close correctly without crashes or ANRs Deliverables are the updated, compile-ready source, a sign...

I need a lightweight chat-style messenger built specifically for Android so I can read incoming messages and send quick replies from the same screen. At this stage I only require the core one-to-one text conversation flow; once that is solid I may extend it to voice notes, file exchange, or group rooms, but those extras are not part of this first milestone. Here is what I expect: • A clean Android Studio project written in Kotlin (Java is fine if you strongly prefer). • Real-time send/receive with message status indicators. You are free to choose Firebase, WebSockets, or any other modern backend you are comfortable with—just keep the setup clear so I can run it locally. • Simple authentication (email/password or phone OTP) so users can log in and start chatting i...

I’m putting together a brand-new SaaS product aimed squarely at fellow developers. The front end will be in React (hooks, functional components, TypeScript preferred), the back end in Node with an Express or layer, and everything will be wired to a cloud-hosted database. My goal right now is to move from a rough concept to a working MVP that other engineers can immediately sign up for, explore the API, and give feedback on usability and performance. Core scope • Design and build the entire stack: React UI, Node/Express API, PostgreSQL (or another relational store you’re comfortable with) • Set up CI/CD so every commit auto-deploys to a staging environment (GitHub Actions, Vercel, Render—open to your usual toolchain) • Developer-friendly documentation:...

I’m building a cross-platform mobile app in Flutter and need help wiring up the NFC layer on each platform. On iOS the job is straightforward: when the user taps an NFC tag, the app should silently read the NDEF text record and present the payload on screen—nothing more, no writing required. Android demands a bit more. Besides reading tags in the same way, the app must also broadcast (beam) an NDEF text message so the IOS phone above or another Android phone can pick it up. A simple UI toggle to switch between “Read” and “Broadcast” modes is enough; the broadcast text can be hard-coded for now so I can change it later in code. Key points • Single Flutter codebase with platform-specific channels only where necessary • Use any well-maintai...

I want to deploy a fully-functional AI assistant built on a free Chinese open-source model—Qwen 2.5, Minimax01, Kimi 1.5 or Open Manus are all acceptable. Phase one is crystal-clear: the system must start producing qualified leads for short-term business loans, bridge loans, consolidation loans, equipment financing, commercial refinance and purchase, and even grant-seekers. Accuracy, compliance, and the ability to track every interaction matter more to me than flashy extras. Here’s how I picture the first release: • Model integration and fine-tuning on my loan-specific prompts and historical data • A lead-generation workflow that scrapes or ingests approved data sources, segments prospects, and outputs clean CSV or pushes directly into my CRM • Simple das...

I want to bring a simple yet rock-solid productivity tool to life: a stand-alone Android app focused entirely on task management. The goal is to give users an uncluttered place to create, edit, prioritise, and complete tasks without needing any extra sign-ups or online services. Here is what I need delivered: • An APK ready for Play-Store submission, plus the full, well-commented source code (Android Studio in Kotlin or Java is fine). • A clean, responsive UI that works smoothly from Android 8.0 up to the latest version. • Core features: add, delete, reorder, and mark tasks as done; assign due dates or simple reminders; quick search or filter by status. • All data stored locally so the app functions fully offline. • Basic settings page (dark/light mode a...

I have a live application that requires two things right now: thorough bug fixes and targeted feature enhancements in several existing modules. The codebase is stable overall, but a handful of issues are affecting user flow, and I want to introduce a few practical improvements while we are in the code. You will start by reviewing the current implementation, reproducing each reported issue, and patching the bugs so they are no longer repeatable in staging or production. At the same time, I would like you to add small-to-medium-sized enhancements that we will agree on together—think quality-of-life tweaks rather than a complete overhaul. If you also spot opportunities for performance improvements, feel free to flag them; we can treat those as a second phase if time allows. Pleas...

I have an existing Android app that is stable but still very lean on features. The immediate goal is two-fold: first, roll out a new “upload” capability inside the app (users need to be able to select a file—primarily images or PDFs—from local storage and send it securely to our backend); second, compile, sign, and publish the updated build to the Google Play Console so the change is live for all users. The current stack is Kotlin with standard Android Jetpack libraries; the backend is ready and exposes a REST endpoint for the upload, so the mobile side only needs to handle file selection, progress indication, and a simple success/fail response. If you prefer Java that’s fine—as long as the final APK/AAB plays nicely with our existing codebase. Deliver...

The goal is to end up with a clean, scalable Selenium WebDriver framework in Java that any engineer on my team can pick up and extend. It must follow the Page Object Model throughout, execute through TestNG, and generate rich reports with either Extent or Allure—whichever you feel gives the clearest insights. Parallel execution is a must, and every test should run reliably on Chrome, Firefox, and Edge. Running the suite in headless mode isn’t required for now. A tidy repository structure, meaningful package naming, and a well-commented README are just as important to me as the code itself, so please factor that documentation time in. All work will be version-controlled in a new GitHub repository that you initiate and populate with an agreed branching model. Deliverables &bu...

I need my existing app wired up to an existing external REST API so it can securely fetch data, submit updates, handle authentication, and allow users to upload files. Most endpoints accept/return JSON, and uploads are sent as multipart/form-data — your code must handle both cleanly and reliably. Deliverables: A small, reusable, well-typed API client layer (e.g., /lib/api or similar) using fetch or Axios Authentication integration (bearer tokens / OAuth details provided).

Android App UI Replica (Jetpack Compose) General Information I have an existing Android application only as an APK file. There is no Android Studio source code — only a decoded version via apktool (res, drawable, xml, png, smali). The app is written using Jetpack Compose, so this task is NOT reverse engineering.

I need a Telegram-based AI assistant that can act as a true subject-matter expert. The core idea is simple: we will feed it a large, well-structured document set from whichever industry offers the richest material, then let the bot do the heavy lifting. While the sector itself can be decided once I see which corpus is most complete, the bot must speak fluently about Artificial Intelligence concepts in particular, as that will be a recurring theme in user queries. Once deployed the assistant should: • read and index every document I supply (PDFs, Word files, web links, internal wikis) • answer ad-hoc questions instantly, citing sources • provide actionable recommendations where appropriate • deliver concise summaries of lengthy texts on request I expect a smo...

I want to commission a full-featured Android application dedicated to organising eSport scrimmages and small-scale tournaments. My budget for the entire build is approximately US $1,000, which I will release in clearly defined milestones (prototype, beta, final release, and demo video). Core scope The app has to let players create and manage teams, schedule matches effortlessly, and keep ongoing statistics so organisers can review past performances. Because most users will expect a quick sign-up flow, social-media login options (Google, Facebook, Twitter) need to be baked in from the start. I also need a lightweight in-app payment gateway so teams can pay entry fees or unlock premium brackets without leaving the platform. Deliverables • Production-ready Android APK and source co...

I'm looking for an experienced programmer to create a custom plugin/mod for the upcoming Spellbound SMP. All details for the plugin can be found in the document below. On this SMP, I'd like the first hostile mob a player kills to grant that player a buff, based on the mob in question. This assigned buff can only be reversed via use of a Reset Star, the recipe for which is also found in my doc. Our budget to start is $100, although a larger price is negotiable. I've wanted to do this for a very long time, and it'd mean a lot to me and my community if you can help me with it. It should go without saying that you'll be fully credited for your work in the descriptions of all my videos, and if you'd like to join the SMP once this is done, you can. I'd prefe...

I’ve reached the final polishing phase of my mobile game and now need a fresh set of eyes to put every Android build through its paces. Your task is to install each release on real devices (emulators alone will not be enough), explore every menu, level, and feature, and then document anything that feels broken, confusing, unbalanced, or sluggish. Please capture issues in clear English, attach screenshots or screen-recordings where visuals help, and note the device model, OS version, and steps to reproduce so my dev team can act on them quickly. Performance metrics such as load times, frame-rate drops, battery drain, and unexpected data usage are especially valuable. I’ll share the current APK, change-log, and a brief list of focus areas as soon as we start. We’ll wo...

The FIGMA for my credit-card-offers app is complete; now I need the server-side engine that will make the screens come alive. The scope is an MVP-ready backend built from scratch, including both the API layer and a brand-new database. The will work in sync with a browser extension being developed separately.

Need to develop both Android and iOS.

I need a clean, modern Android application that lets diners browse our menu with attractive photos, clear prices, and smooth yet simple animations. Customers will be able to place an order straight from the app; instead of a payment gateway the order screen will simply present the restaurant’s phone number so they can call or message us to confirm. Only dish names and prices should appear—no long ingredient lists—and absolutely no purchase-history screen is to be stored or shown. An admin area must exist, hidden behind a single secret code. Once inside, the authorised person can add, remove, or swap dish names, photos, and prices. No other user should even see that this option exists. Deliverables • Full Android Studio project and signed APK • Admin code ...

We need an Android developer to add iPhone-style panorama to the Open Camera app (open source: ). Goal: Implement panorama in Open Camera so it works like iPhone: guided on-screen motion, smooth horizontal panning, and one stitched panorama image. • Works seamlessly on both the front and back cameras. • Guides the user with the same arrow-line UI Apple uses, keeping motion smooth and level. • Captures a continuous series of frames, stitches them on-device, and outputs one high-quality image without pushing memory limits. You’ll work only against the official Open Camera codebase (or a clean fork you create). I’ll take your branch and merge it into our own app later.

I need help changing the visible name of an Android application that is already installed (or will be installed shortly). I will supply the current package and the existing project files; the new label itself is still undecided, so I’m counting on you to make the switch once I confirm the wording. The task is limited to the app-name label only—no package-ID or code-level refactoring is required. I will just get the apk file from you and i will reinstall it to the device. Or you will just rename the application in my device.
