Szymon worked on the ava-labs/core-mobile repository, focusing on performance, stability, and environment-aware improvements over a two-month period. He optimized startup time by addressing polyfill issues and enhanced UI stability through screen freezing, resulting in a smoother user experience. Szymon also reduced jailbreak detection latency and upgraded build tooling to improve developer iteration cycles. In addition, he refactored the watchListCache client to support separate development and production environments, introducing environment-based validation and explicit type inference for API responses. His work leveraged JavaScript, React Native, and build system configuration, demonstrating depth in both performance optimization and maintainable code structure.

November 2025: Delivered environment-aware watchListCache client with improved API handling for ava-labs/core-mobile, enabling separate development and production clients, environment-based validation, and robust production requests using axios.create. This refactor enhances reliability, reduces environment drift, and improves type safety and maintainability.
