Rockstar🎓
Top SchoolGreg Kaczan is a Lead Frontend Engineer with over 14 years of hands-on experience building and modernizing complex web applications, currently driving frontend development at Soda from Wrocław, Poland. He specializes in React, TypeScript and GraphQL, is an early GraphQL adopter and a Node.js enthusiast who also rapidly mastered a complex Angular codebase in three months. Greg has led large migrations from legacy jQuery/SSR stacks to modular React/Relay architectures, improved developer experience by replacing Java-based tooling with modern bundlers, and established company-wide frontend practices including CI/CD and automated QA. He balances leadership—mentoring teams and removing blockers—with deep engineering: shipping integrations like the SodaCloud GitHub action and implementing end-to-end testing with Cypress. Notably, he thrives in small cross-stack teams where he moves quickly from proof-of-concept to production-grade solutions.
