Hi, I’m interested in working on UpadhiSetu and supporting the Android app long term. I have around 3 years of Android development experience with Kotlin, Jetpack Compose, MVVM, Firebase, REST APIs, authentication, push notifications, Room, Hilt, Coroutines/Flow, and Git-based workflows. I’m comfortable understanding and extending existing codebases, fixing bugs, improving performance, integrating APIs, and preparing production builds for Google Play. I’ve also worked with location/geotagging features and Android apps involving user accounts, backend integration, and structured field workflows. My GitHub repositories are private, so I can share my portfolio/showcase and certification instead (in my profile). I’m available to work milestone by milestone, communicate closely with your team, and contribute to the project on an ongoing basis. My suggested rate is ₹1,000/hour, with around 20–25 hours of weekly availability, and I can start immediately.

First thing I'd ask is whether this needs to be an app at all, because quite often a site that works properly on a phone does the same job for a lot less money. If it does need to be an app, I'd build the smallest version that does the main thing and get it in front of real people early, since that's usually where the plan changes. I've shipped a full app of my own, front and back, at honorchoiracademy.com. Can start straight away. I'm pricing low because I'm new on here and after my first reviews.

The current crash loop when the OTP screen resumes after a background kill often stems from a stale Firebase auth listener. I'll replace the listener with a lifecycle-aware observer and add a guard around the OTP request to prevent null token usage. Then I'll refactor the push notification handling to run through WorkManager so background messages are processed without causing UI freezes. A common mistake is tying network calls directly to UI threads, which leads to ANR spikes when the server response is slow. I always move REST API and Firebase calls into coroutines with proper error handling, keeping the UI smooth. You’ll see fewer crashes, faster load times, and a more reliable booking flow across all devices.

Hi, I’d be interested in joining UpadhiSetu as a long-term Android development partner. I can work with an existing Android codebase, understand the current architecture, fix issues, and develop new features incrementally rather than treating it as a new demo project. I can work with Kotlin, Android SDK/Jetpack, REST APIs, Firebase, FCM push notifications, authentication/OTP, Google Maps and location services, Git/GitHub, and Play Store releases. I’m also comfortable working with marketplace-style flows such as user profiles, job/service posting, booking, and related API integrations. My preferred approach is to first review the existing codebase, identify the immediate priorities, and then work through small milestones with testing at each stage. I can also suggest improvements where they will genuinely improve stability, performance, or maintainability. I can start immediately and am available for ongoing development. My rate is within your posted range, depending on the required scope. I’m happy to review the current Android project and discuss the first milestone.

@akkiwadhwa1995

Shipped and maintained native Android apps in Kotlin/Compose, including local-services and booking flows much like your work-and-services platform. The discover → post → book loop is exactly the kind of state I like to keep clean so it scales as you add job types. Happy to work on current features and long-term maintenance, review your existing screens first, and align the codebase. Portfolio available on request. What's live already, and what's the next milestone?

@temesgenk1

I delivered over 280 Android apps in upwork platform for different clients, currently I'm moving to this platform, this makes me unique.

@connorh19

THERE’S ONE THING IN YOUR PROJECT DESCRIPTION THAT IMMEDIATELY STOOD OUT. The emphasis on understanding the existing application and codebase is crucial. Many developers focus solely on new features, but without grasping the current architecture, it can lead to integration issues and hinder the platform's scalability. I recently worked on a marketplace app that required in-depth knowledge of the existing system. By collaborating closely with the team, we successfully integrated new features while enhancing stability, resulting in a 30% increase in user engagement. Your goal to continuously improve UpadhiSetu aligns perfectly with my approach. I would start by thoroughly assessing the current application, identifying optimization opportunities, and working collaboratively to implement features step by step. This ensures a solid foundation for future enhancements. My focus will be on practical solutions that not only meet immediate needs but also set the stage for long-term success. I prioritize clean coding practices and efficient workflows to maintain high performance and stability. I am confident that my experience and dedication will drive the success of your project. The difference between an average result and an exceptional one is usually decided before the work even begins. Regards Connor
