I’m a Senior Frontend Engineer and game developer with over a decade of experience designing high-performance web platforms and building interactive systems. I enjoy bridging robust web architecture—especially with Next.js, React, and TypeScript—with game logic and real-time data flows, always aiming for smooth, accessible user experiences. Through roles spanning enterprise fintech and customer-facing applications to indie development and technical consulting, I’ve focused on scalable architecture, observability, and reliable engineering practices. I also like pushing boundaries with AI-enabled workflows and modern tooling, whether I’m shaping secure backend services in Go or building localized, high-load frontends that feel great for users worldwide.
