Summary
🤩
Rockstar🎓
Top SchoolJaroslav Kubíček is a pragmatic full-stack software engineer with 13 years' experience, strongest on the frontend and based in Prague. He specializes in TypeScript and React, but routinely owns end-to-end features that touch Kotlin/Spring and Node.js, blending product-minded thinking with implementation. At Productboard he shipped enterprise-focused RBAC and data-quality features and led a React 19 migration and performance work that unlocked concurrent rendering across the app. Previously he improved developer experience at scale—building a Tilt-based CLI and local environment tooling that saved dozens of engineers hours weekly—and contributes to open-source UI work like Kiwi.com's Orbit React components. He pairs a developer-experience mindset with curiosity about architecture and automation, often asking "who is this for?" before writing a line of code.
