About

Frontend Engineer with 6+ years of experience building web and TV products with React, React Native, LightningJS, and TypeScript. My background includes 5+ years in OTT/video products and 2+ years hands-on with Smart TV applications. At AgileTV, I develop a performance-critical Smart TV interface with LightningJS, using list virtualization and rendering optimizations to sustain 60 fps on target devices. Previously, I worked on video-player and purchase flows with React Native, ReNative, and Bitmovin, and spent 17 months coordinating multi-platform delivery across five countries.

Why I do this

I like frontend work where the product experience depends on details users never see: rendering cost, input latency, state transitions, and recovery from failure. Today I build a performance-critical Smart TV interface with LightningJS, using list virtualization and rendering optimizations to keep navigation smooth at 60 fps on target devices. My previous OTT work included video-player and purchase flows with React Native, ReNative, and Bitmovin.
