Ionly Indian apply- have an existing Android application written in a mix of Java and Kotlin, and several screens rely on real-time data over [login to view URL] / WebSocket. One core feature is currently malfunctioning, so the first priority is to trace the issue, patch the code, and deliver a stable build that passes regression testing. Once the fix is in place, I’d like to move straight into adding a couple of new functions (we can finalise the exact scope together, but they will sit on top of the same real-time layer). Clean, well-commented code and Git-based commits are a must so I can review each change. Deliverables • Updated source code with the malfunction resolved • New feature branch merged into main after my sign-off • Release-ready APK / AAB plus a short change-log Acceptance criteria – Feature works consistently across Android 8+ devices – WebSocket connections stay alive or gracefully reconnect – No new crashes flagged by Firebase Crashlytics If you’re comfortable juggling Java, Kotlin, and [login to view URL], and you enjoy digging into existing codebases, let’s get started right away.

Hi, I noticed your Android app uses a mix of Java and Kotlin with multiple screens depending on various integrations. Debugging hybrid codebases like this often involves tracing issues across language boundaries and ensuring consistent behavior throughout the app. Over the past decade, I have worked extensively with Android development using both Kotlin and Java, along with API integrations, clean architecture patterns, and mobile applications that need to perform reliably at scale. I am comfortable navigating mixed-language projects and identifying where bugs originate, whether in the UI layer, business logic, or backend communication. Here is how I would approach this: - Review the codebase structure and reproduce the reported bugs in a local environment to understand their root causes - Trace issues across Java and Kotlin boundaries, checking for interoperability problems or inconsistent state handling - Implement fixes with proper regression testing to confirm existing functionality remains intact - Document any enhancements and ensure the changes follow your current code style and architecture Are the bugs primarily related to specific screens, API responses, or occurring more broadly across the application? I am available to start immediately and can provide regular progress updates as I work through the issues. Let me know if you would like to discuss the details further. Best regards, Hector R.

Could you provide more details about the malfunctioning feature? Are there any specific error messages or behaviors you’ve noticed? With over 5 years of experience in Android development using Java and Kotlin, I can quickly trace and fix the issue with your real-time data connections. I’ll ensure the code remains clean and well-documented, aligning with your requirements for Git-based commits for transparency. Once the core feature is stable and passes regression testing, I’m ready to collaborate on adding the new functions as discussed. I’ll deliver an updated source code, along with a release-ready APK/AAB and a concise change-log to document the changes made.
