What I'm looking for

I'm looking to build high-performance systems and AI-native tooling where I can solve difficult performance, reliability, and architecture problems with cross-functional teams.

At Miro, I work on the core board engine, improving main drawing-engine performance by 50% and making the performance-optimization workflow AI-native. I built a custom tracing and replay format for automated performance testing and implemented about 30 React-like features and APIs.

I've built market-connectivity modules at Exness, automotive components at Harman, and web, blockchain, desktop, and trading systems across earlier roles. My work spans C++, Python, distributed systems, performance profiling, multithreading, AI inference, and production debugging, with outcomes including a 13% core-engine improvement and 10x legacy-code performance gains.
