What I'm looking for

I’m looking for a staff-level Android role in fintech/mobile banking where I can lead architecture, security, build performance, and observability—partnering across vendors and mentoring teams to raise the engineering bar.

I’m a Staff-level Android engineer with 10+ years building production fintech at scale—mobile banking, payments, open banking, POS, KYC, security, and monitoring. I go deep in Kotlin and Jetpack Compose, and I drive multi-module Clean Architecture with Coroutines/Flow and Hilt to ship reliable, end-to-end experiences across Android and partner integrations.

I set technical direction beyond a single team: I own build performance, observability, and security architecture, and I resolve cross-vendor and cryptographic problems. As an Android Chapter Lead, I set architectural standards, improved release build times, led ANR investigations, and built runtime app-security perimeters (encryption, session management, fraud signals, and digital signing) while mentoring teams and raising engineering quality through CI/CD foundations and code-style standards.
