Top SchoolViacheslav Demchenko is a frontend developer based in Krakow with five years of hands-on experience building React-based interfaces and migrating legacy JavaScript to TypeScript for improved maintainability. He has delivered production-grade admin dashboards, data-heavy UIs and cross-platform startup apps, and has full‑stack experience building REST APIs with Python and Django when projects demanded it.
