Frontend developer
I create impressive, innovative and impactful software solutions for the web.
About
I'm Frontend Developer based in Prague, Czechia. I specialize in building performant, accessible, and scalable web applications. With over 3+ years of experience in industries like finance and healthcare I bring both technical expertise to every project.
Currently, I'm working at Publicis Groupe where I build and maintain web apps for various clients using modern tech stack including Next.js, Gatsby.js and React, I focus on code quality, testing (Jest, RTL), and team collaboration, contributing to internal tooling to boost developer efficiency.
Previously at Česká Spořitelna, I developed banking apps, led frontend improvements, and collaborated with analysts and backend developers to deliver reliable and well-tested solutions that supported cards, ATMs, and refund operations.
My toolkit includes React, TypeScript, and many complementary tools and libraries. I'm always eager to work in teams that value quality, innovation, and user-first design.
Outside of tech, I'm passionate about psychology, natural science, fitness, and travel. I believe that great products start with understanding people—and I strive to create experiences that are both meaningful and impactful.
