My objective
A developer with 2.5+ years of commercial experience building responsive, scalable SPAs using
React, TypeScript, and Node.js. I have participated in 4–6 production projects as part of cross-
functional teams of 5–6 people, working closely with backend, design, and QA specialists. I
prioritize clean code, a well-structured component architecture, and a smooth user experience
across different browsers and devices. I hold a bachelor’s degree in computer science, which
combines a solid theoretical foundation with practical experience in product development. I am
currently seeking a position as a Full-Stack or Frontend Developer where I can continue to grow
technically and contribute to the creation of high-quality products for users.

Work experience

Jun 2025 – Present Self-employed Freelance Full-Stack Developer

specific business needs and brand.

Feb – Jun 2025 AASSolutions, a.s. Junior Frontend Developer

systems.
Integrating the frontend with backend services via REST API and SOAP.
