Kotlin Jobs

I would like to develop a calling feature for my existing project, including both one-to-one calls and group calls. Our backend is already developed and fully tested, so the server-side functionality is ready. The one-to-one call will use WebRTC, and group calling will be handled through our MediaSoup server. At this stage, we need a developer to build the front-end implementation using Flutter or Kotlin in a separate project, which will communicate with our existing backend APIs. Once the calling features are successfully implemented and tested, we will merge the Flutter / Kotlin front-end logic into our main Flutter application. Please let me know if you can handle this task, and kindly provide proper documentation, a budget estimate, and a project timeline. Thank you.

I’m ready to launch a dedicated Android e-commerce application that will showcase and sell physical products only. The goal is a smooth, secure shopping experience from browsing to checkout, built natively (Kotlin/Java) or with a reliable framework such as Flutter—whichever you’re most comfortable with for optimal Android performance. Core flow I have in mind: a clean product catalogue, searchable categories, detailed item pages, a persistent cart, integrated payment gateway, and basic order-tracking for customers. I will provide product data and branding assets; I need you to turn them into a polished APK, connected to a lightweight admin dashboard or API of your choice so I can manage inventory and fulfil orders without touching code. Please keep the initial release A...

I’m bringing Likandflow to life as a dedicated Android application and need a developer who can take it from concept to a polished launch-ready build. The first milestone is rock-solid user authentication—secure sign-up, log-in, and password recovery—with clean error handling and a future-proof structure that makes it easy to extend into features such as push notifications or in-app purchases later on. You’ll handle the entire Android stack: UI that follows Material Design, Kotlin or Java (your preference, as long as code is well-structured and documented), interaction with a back-end auth service (Firebase Auth works, but I’m open to your suggestion), and creating a signed release APK plus source in a Git repository. Once I can install the APK, create an ...

Project Title: Android App Development – Minimal Position Size Calculator (Kotlin + Jetpack Compose) Project Overview I am building a minimal Android trading utility that calculates position size based on risk management. The goal is to create a fast, clean, and reliable calculator used by traders before entering a trade. This is Version 1 of the app, so the scope is intentionally small. The focus is on excellent UX, performance, and code quality, not on feature quantity. Future versions will expand into a full trading journal, so the codebase should be clean and extensible. Key Requirements The app must be: Native Android Smooth and responsive Minimal and aesthetically clean Fully offline Privacy-first (no login, no tracking) Technology Requirements Please use: Kotlin...

My Kotlin-based Android app needs attention on two fronts. First, I’m running into “update functionality” issues: certain screens don’t behave as they should after recent code changes, and a clean, crash-free build is now a priority. Second, I want the interface to feel identical to the already-polished iOS version. That means revisiting layout decisions, refining graphics/icons where they look off, and smoothing the overall navigational flow while we’re in there. Think material-compliant but visually in sync with iOS. Once stability is restored, I’d also like you to roll in a couple of small new features lurking in the current product roadmap (all scoped, with designs ready to hand over). Deliverables • Debugged APK and updated source wi...

I have an Android Studio project that needs some spring-cleaning before we add a small new feature. First, the housekeeping: • strip out any dead or unused classes, methods, and resources • refactor what remains so the codebase is readable, well-named, and lint-warning free • resolve a couple of known crashes and UI glitches Once that baseline is solid, I’d like a new dropdown on the main screen. It only has to show a static list that ships with the app—no dynamic filtering or server fetches right now—but please wire it so it can be extended easily later. The app is built with Kotlin (with a few legacy Java files), Gradle 8, minSdk 24. I’ll provide Git access and notes on the bugs I’m seeing. Deliverables • Clean compile with zero...

I need a straightforward Android application that lets registered grocery users browse a product pricelist and narrow it down by local brand name. When an item appears on-screen it should show only two fields—price and a short description—so the layout stays clean and readable. Core flow • A user signs up (or logs in) under the single available category: Area in which user is located. • Once inside, they see the full grocery pricelist pulled from a small dataset or back-end of your choice. • A filter control lets them pick the local brand they’re interested in, instantly updating the list in place. • An optional image upload screen is required so that I, as the admin, can attach a product photo or company logo for future use, even though image...

I’m ready to turn a concept into a full-fledged social media experience built specifically for Android. At its heart the app must give users a smooth way to create a personal profile, exchange real-time messages, and share photos or videos as effortlessly as they would on any top-tier platform. I want a clean, modern Material-based interface, fast loading feeds, and a backend architecture that can scale gracefully as the community grows. You’re free to choose the stack you feel is best—Kotlin with Jetpack components, or perhaps Flutter if it still delivers a first-class Android experience—but the end result should look and feel native. If Firebase, AWS Amplify, or your own custom Node/Express + MongoDB setup will get us to reliable authentication, media storage, pu...

I’m looking to roll out a dedicated Android app that lets my site engineers capture everything that happens on a construction project—while they are still on-site. Core workflow The app opens to a simple dashboard where the crew can: • File a structured daily report (labour, materials, weather, notes). • Attach and annotate unlimited photos straight from the phone camera. • Create, assign, and update tasks so I can track execution in real time. What matters most to me is speed and offline reliability: if there’s no signal, data should sync automatically once the device reconnects.
