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. Comfortable in Scrum teams, he emphasizes code quality—introducing standards, reviewing PRs, and creating reusable extensions and templates that reduced errors and saved time across departments. Early experience automating warehouse diagnostics with a custom Python/TkInter tool highlights his practical problem-solving and willingness to own end-to-end solutions. Now focused on frontend excellence, he combines performance-minded UI work with a pragmatic backend understanding that speeds integration and delivery.
