What I'm looking for

I’m looking to build scalable, secure fintech/banking Android apps, own architecture and performance, and ship reliably through strong CI/CD—working with cross-functional and security teams to deliver trustworthy payment experiences.

Senior Android Engineer with 5+ years building fintech and banking applications at scale. I specialize in the kind of work that doesn't make headlines but keeps products alive — architectural ownership, codebase modularization, security-grade reliability, and the technical decisions that make future features possible without burning the team down.

I've led squads, initiated micro-frontend modularization across large codebases, built CI/CD pipelines from scratch, and collaborated with security teams on penetration testing for payment-critical systems. All in high-traffic, enterprise-grade environments where getting it wrong has real consequences.

My engineering mindset: build systems that are easy to change, not just easy to ship. Leave the codebase better than you found it. Make the next engineer's life easier.

Tech: Kotlin · Jetpack Compose · MVVM · Clean Architecture · Dagger-Hilt · Firebase · GitHub Actions · REST APIs

Currently open to Senior Android opportunities globally — open to any time zone, any market, as long as the engineering culture is right.
