Summary
👤
Senior🎓
Top SchoolTomas Holas is a pragmatic frontend‑leaning fullstack engineer with 17 years of experience building high‑performance web and mobile UIs that hide significant technical complexity behind effortless interactions. He specializes in React/TypeScript, MobX and Flutter, with a track record of architecting real‑time systems and visualizations that scale to tens of thousands of concurrent items. Tomas favors zen‑like simplicity—isolating complexity in deterministic state architectures so the surface UI remains pure, predictable and fast. His work spans enterprise modernization, cross‑platform apps, and AI‑driven features (real‑time transcription and agentic workflows), and he’s repeatedly turned legacy products into modern, production‑ready systems. Based in Prague, he combines a background in biomedical engineering with deep practical experience, often bringing unexpected clarity to messy legacy codebases.
