What I'm looking for

I seek a remote or relocatable role building fullstack web applications using React/TypeScript, contributing to performance, testing, and mentoring.

I am a Fullstack developer with a Master’s degree in Computer Science (nostrified in the Czech Republic), experienced in building web applications using JavaScript and TypeScript, React, Next.js, Node.js, and relational databases. I deliver production-ready code and have reduced load times and bug rates through performance optimizations and automated testing.

As a mentor and instructor I supported 20+ students at Mate Academy, developed an internal LMS, and reviewed projects while guiding teams to better workflows. In freelance and professional roles I implemented CRUD systems, REST/GraphQL APIs, OAuth2 authentication, and CI/CD practices across frontend and backend stacks.

I am proactive, a quick learner, and comfortable with modern tooling (Webpack, Docker, Cypress, Jest, Git). I seek opportunities to contribute to innovative web products and scale reliable, high-performance user experiences.
