I’m maintaining a live Android application that serves both smartphones and tablets, and I need part-time help keeping it in top shape. Your main focus will be twofold: first, diagnose and eliminate the bugs users surface through Firebase crash logs; second, build out the new features on my product roadmap so the app keeps evolving. The codebase is Kotlin-first (some legacy Java remains) and network traffic flows through Retrofit, so solid Retrofit experience is a must. We’re on Android Studio Flamingo, minSdk 24, using an MVVM architecture with ViewModel and LiveData/Flow—if you have ideas to improve performance or structure, I’m happy to hear them as long as they fit smoothly into what’s already there. Each week you’ll pick up tickets from Jira, push well-documented commits to our private Git repo, and open small pull requests that pass the CI pipeline. Typical work ranges from patching a crash to extending a Retrofit interface for a new endpoint, then wiring up the UI so it looks great on both phone and tablet layouts. After your code merges, a short release note summarizing changes completes the cycle. Deliverables • Merged pull requests that compile cleanly and pass automated tests • Brief release notes for each completed ticket Please include one or two examples that highlight your Retrofit work and let me know roughly how many hours you can commit per week.

Hi, You need part-time help on a live Kotlin Android app (phones + tablets): fix Firebase crashes and ship roadmap features — Retrofit, MVVM, ViewModel, LiveData/Flow, Jira → PR → CI → short release notes. I work in native Android (Kotlin, legacy Java) with Retrofit + MVVM in production. Retrofit examples: merchant/distributor apps — REST interfaces for orders, inventory, and auth; new endpoints wired through ViewModels with Flow/LiveData and tablet-aware layouts. I’m used to crash triage from Firebase (stack trace → root cause → minimal fix) without disturbing existing structure. Availability: ~10–15 hours/week (flexible if a hotfix needs more). Deliverables: clean PRs that pass CI, brief release notes per ticket. Best regards

You need someone who can trace production crashes to their real cause, patch them without disturbing existing behavior, and extend the roadmap through small, reviewable changes. I’ve maintained production mobile applications with Java-based components, REST APIs, asynchronous state handling, Firebase diagnostics, Git workflows, and CI-tested releases. I’m comfortable working inside an established Kotlin MVVM structure rather than proposing a rewrite. For crash tickets, I’ll reproduce from Firebase Crashlytics context, device and OS data, identify the failing state or lifecycle path, add a focused regression test where practical, and keep the pull request limited to the verified fix. For feature work, Retrofit contracts, DTO mapping, repository logic, ViewModel state, error handling, and phone/tablet layouts will be updated together so API failures do not leave the UI inconsistent. Every PR will include clear commits, testing notes, compatibility checks from minSdk 24 upward, and a concise release summary. What are the current crash-free user rate, automated test coverage, and most urgent Jira tickets?

For a live Kotlin-first app using MVVM, Retrofit, ViewModel, and LiveData/Flow, I’d work inside the existing architecture rather than introduce disruptive rewrites while the product is actively shipping. My first step would be to triage Firebase crash reports by frequency, affected Android version/device, stack trace, and regression risk, then reproduce and fix the highest-impact issues. For feature tickets, I’d extend Retrofit interfaces/services, map responses cleanly into the ViewModel layer, and keep phone/tablet layouts consistent. My two priorities would be maintainability and user experience: small focused PRs reduce release risk, while responsive UI work keeps new features polished across both form factors. I’m comfortable with Jira-driven delivery, Git workflows, CI checks, release notes, Kotlin/Java mixed codebases, REST APIs, and incremental refactoring where it clearly improves stability. A relevant mobile example is Moholla, a multi-app ecosystem with customer, driver, and shop-owner apps released on both Play Store and App Store, involving role-based mobile workflows and production maintenance. I can commit around 20–25 hours per week. I won’t invent Retrofit-specific project references where I don’t have a verified example, but I’m comfortable working with Retrofit-based API layers in an existing Android codebase.

Ongoing Firebase crash work usually splits into two piles: real null-safety bugs, and noise from OEM webview quirks on tablets. Sorting that first saves weeks. I'll pick up Jira tickets, ship small PRs against your MVVM setup, extend Retrofit interfaces cleanly, and write the release notes. One catch worth flagging: Retrofit's Flow adapter behaves differently on cancellation than LiveData, easy to leak scopes if mixed. 1) Which Retrofit converter, Moshi or Gson? 2) Is CI on GitHub Actions or Bitrise?

Your live app should keep running smoothly while new features land without extra mess. I can start right now. In 24 to 48 hours I will send a working sample: one user crash cleaned up and one small new screen that looks right on phone and tablet. You see that first, then we continue. I already run live production systems and paid client software. I will pick up your list, send small clean updates, and leave a short note after each change so you always know what went out. Which crash or new feature should I use for that first sample?

Hi — I work in exactly this stack daily (Kotlin, Retrofit, MVVM with ViewModel + Flow/LiveData, Firebase Crashlytics), so I can be productive in your codebase quickly rather than ramping up on your time. How I'd work: 1) Crashes fixed by root cause, not guesswork. Crashlytics gives the stack trace, but I trace it to the real cause (a null, a threading/lifecycle issue, a bad Retrofit response), reproduce it, fix it, and confirm the crash rate actually drops in Crashlytics — rather than patching the top line and hoping. 2) Features that fit your architecture. New roadmap features built the MVVM + Flow way your app already works, so they integrate cleanly and don't pile on tech debt. I'll only suggest structural/perf changes where they slot in smoothly, exactly as you asked. 3) Phones and tablets both. I'll test across form factors since you support both, so a fix or feature doesn't look right on one and break on the other. 4) Clear cadence for ongoing work. Since this is continuous, I'd report what's fixed and shipped each cycle so you always know the state of the app. To scope the first sprint: what's your current crash-free rate / how many active crashes? What's next on the roadmap? And can you share repo + Crashlytics access? 3 days for a first sprint (crash batch + first feature), then ongoing. Thanks!
