Building scalable mobile applications used by large user bases.
I’m a Mobile Engineer with 5+ years of professional experience building Android and Flutter applications across fintech, retail, and food-tech domains.
I’ve worked on products serving 1M+ users and systems managing 100K+ active groups, where performance, stability, and maintainability actually matter—not just feature delivery.
My focus is on:
- clean, readable, and testable code
- scalable architectures
- long-term maintainability over short-term hacks
I strongly believe in building software right from the start, which is why I actively practice Clean Architecture, SOLID principles, and Test-Driven Development (TDD).

I prioritize correctness, readability, and maintainability over short-term speed. I prefer fewer abstractions done right rather than complex systems done fast.
