Frontend Engineer at a telemedicine startup who rebuilt WebRTC calling and cut dropped calls by 7%.
ItalyWhat I'm looking for
At a Confidential US Telemedicine Startup, I own the real-time layer for patient–doctor messaging and video consultations. I rebuilt the WebRTC connection flow around backend-issued TURN credentials and ICE restart, reducing dropped calls by 7%.
I re-architected a 2,000-line WebSocket handler into 13 feature-sliced modules and consolidated 30+ legacy components into a shared UI kit. I also cut chat re-renders by about 30%, helping conversations with 3,000+ messages scroll smoothly.
At EPAM Systems, I delivered products for govtech, fintech and social clients, including a building-permit portal and a React Native/Expo social app MVP. I built 80+ screens and 130+ reusable components, and improved key routes’ loading performance through code splitting and lazy loading.
At Invisalign Center, I built an internal SPA for partner orthodontists that processed 3,000+ clinical cases, and shipped more than 30 marketing landing pages. I also ran user research and A/B tests, cutting time to conversion on a key page by 12%.
