Summary

Rockstar🎓
Top SchoolMilos Vetesnik is a co-founder and front-end engineer with a decade of experience building user-focused web applications from Czechia. As co-founder and managing director of Excalidraw, he helped create the popular hand-drawn virtual whiteboard, driving key React-based UX features, collaboration performance optimizations, and analytics-driven flows. He also co-founded Keybu, where he wore many hats—server and security setup, product ownership, and co-developing a custom SPA framework—showing full-stack fluency from nginx and Postgres to Node.js and Cypress testing. Comfortable moving between product, engineering and ops, he combines startup grit with practical security and deployment know-how. Uncommonly for a front-end lead, he’s deeply involved in backend infrastructure and anti-abuse systems, reflecting a broad, production-minded engineering approach.
