About Me

Introduction
I'm a developer passionate about building reliable, efficient, and maintainable software. I enjoy diving into complex problems and designing solutions that work seamlessly and scale effectively. My focus is on crafting functionality that is not only robust and performant but also thoughtfully engineered to stand the test of time and real-world use cases.
Current Role
Currently, I'm a Medior Full-Stack Developer at PSS a.s, specializing in Angular-TS and Java - SpringBoot. I contribute to the creation and maintenance of scalable web applications that power our platform, ensuring our products meet web accessibility standards and best practices to deliver an inclusive user experience.
Background
I studied Robotics and Cybernetics at a technical school. During my studies, I began working part-time as a web and backend tester. From this testing position, I progressed to a full-stack developer role, gaining experience across both frontend and backend development.
Personal
In my spare time, I'm usually hitting the gym, or working on side projects to explore new technologies and frameworks.
