What I'm looking for

I’m looking for a senior Android role where I can own scalable architectures, build real-time mobile systems, and mentor engineers—especially on high-reliability, performance-focused products.

I’m a Senior Android developer with 8+ years of experience building production-grade Android applications across iGaming POS terminals, fitness & health platforms, and entertainment products. I design scalable multi-module architectures using Kotlin, Jetpack Compose, MVI/MVVM, and Clean Architecture, and I’m known for mentoring developers while driving architectural decisions. I thrive on turning complex product requirements into maintainable, reliable systems that ship.

At BetConstruct, I led Android development in the Land-Based Solutions team, owning architecture and delivery for the next-generation sportsbook POS platform deployed across 1,200+ terminals internationally. I architected the full application structure using MVI and multi-module architecture, establishing patterns adopted team-wide and improving scalability and long-term maintainability. I also implemented WebSocket-based real-time data synchronization across all POS terminals, delivering sub-second betting updates critical to operator SLA requirements.

I expanded terminal capabilities with NFC-based workflows (tag detection and event handling) and strengthened release reliability with a custom OTA update system that eliminated manual release downtime. I optimized crash-free performance on Pocket Betshop from an unstable baseline to 99% crash-free by leading a full codebase refactor on specialized POS hardware. Across products, I balance clean architecture with performance and quality—supported by thorough code reviews and hands-on mentoring.
