Summary
👤
Senior🎓
Top SchoolKonrad Kamiński is a Frontend Developer and former Graphic Designer with over 10 years of experience building polished, user-focused web interfaces from Warsaw. He blends visual design sensibilities with modern frontend toolchains (Vue, JavaScript, Sass, Webpack) and hands-on experience with animations and 3D (GSAP, Three.js) to create engaging experiences. While primarily frontend-focused at FOSS and previous agencies, he also contributes to backend open-source projects—adding Kotlin coroutine and reactive integrations to high-profile repos like Micronaut and kotlinx.coroutines—demonstrating strong cross-stack fluency. That uncommon mix of design craftsmanship and low-level concurrent programming lets him bridge UX and performance considerations when shipping complex web applications.
