What I'm looking for

I’m looking for a Senior Android role where I can own end-to-end feature delivery, design clean scalable architectures, and ship secure, high-performance apps—while collaborating in a strong product-focused team.

I’m a Senior Android Developer with 10+ years of experience delivering secure, scalable mobile applications across fintech, banking, telecom, and healthcare. I pride myself on owning complex features end-to-end—from architecture design to Play Store release—while keeping code quality, performance, and security at the center.

At Andersen Lab (06/2025–Present), I work on a large-scale fintech super-app and own key financial flows including cards, deposits, transfers, and replenishment. I design feature modules with Clean Architecture, build complex transaction UIs with Jetpack Compose, enforce architectural standards through code reviews, and contribute to CI/CD and build automation.

Previously at Mudita (11/2022–05/2024), I redesigned AOSP apps (Phone and Contacts) to improve usability, and built a feature-rich Wikipedia app using modern Android architecture. I optimized pagination for memory-constrained hardware, refactored for maintainability and scalability, and maintained unit tests to keep the app stable.

I’ve also built and secured products in demanding environments—leading healthcare feature development and implementing KYC/identity verification workflows with CameraX and TensorFlow at Titanium Technologies, designing a payments architecture from scratch at DNA Payments, and rebuilding Homebank.kz post-acquisition at Halyk Bank. My drive is consistent: ship reliable mobile experiences, mentor others, and continuously improve architectures as the product grows.
