At Board Labs, I engineered and deployed a high-performance Golang server for a multiplayer board game serving over 10,000 monthly active players. I built real-time matchmaking, tournament management, geolocation services, and secure multi-currency payments with Xsolla and Stripe.

I implemented observability with OpenTelemetry and Uptrace to support availability and performance, while using goroutines and channels to solve complex concurrency challenges.

Previously at Zynga, I analyzed High Heels player data and proposed features that increased revenue by 15%. I also helped design a K-Means-based dynamic difficulty system that raised engagement by 10% and developed user-progression analysis using graph and tree data structures.

My work also includes deep-learning research for Ethereum smart-contract vulnerability detection, achieving 96% accuracy and reducing analysis time by 80% against traditional static analyzers. I enjoy applying software engineering, data analysis, and machine learning to products people use.
