What I'm looking for

I’m looking for a role building stable, real-time Android experiences in transactional/financial systems, using Clean Architecture, MVVM, and Jetpack. I want an Agile team where I can ship measurable reliability improvements and collaborate end-to-end.

I’m a Senior Android Engineer with 7+ years building and shipping native Kotlin applications, especially transactional and financial-tracking systems that demand stability and transaction integrity. I focus on reliable delivery, real-time data flows, and production-grade engineering practices.

I’ve proven impact on reliability and performance, including a 98% crash-free session rate, 20% crash reduction, and 30% faster responsiveness. In my current role, I improve UI/UX and background task optimization to keep experiences smooth for stability-critical workflows.

My deep technical strengths include MVVM, Jetpack Compose, Coroutines/Flow, and Clean Architecture, alongside strong REST API integration. I also work across the stack when needed (Angular, Laravel) and have experience aligning engineering execution end-to-end.

Collaboration is central to how I deliver: I partner with firmware and backend teams in Agile environments to ship stable releases on schedule. I’m especially energized by products where secure data flows and dependable transaction processing matter.
