What I'm looking for

I want a technical role where I can lead Android architecture and teams, improve app performance, and build secure, scalable mobile products.

I am a Senior Android Engineer with five years building scalable fintech and e-commerce applications, focused on Kotlin, Clean Architecture and performance optimization. I have led technical teams and architected mobile solutions that passed acquisition due diligence by major payment systems.

At Bank CenterCredit I architected a modular Android Design System used across multiple apps, improved CI/CD pipelines, and boosted an app rating from 3.2 to 4.7 by fixing ANRs, memory issues and startup bottlenecks. I also mentored developers, increased unit test coverage, and integrated cross-platform modules to expand features.

I author open-source libraries (a DI library and a Compose navigation wrapper) and have implemented high-security authentication workflows, robust networking layers and modern Android stacks (Hilt, Room, Coroutines/Flow). I seek to continue delivering reliable, maintainable mobile products with a strong focus on quality and performance.
