I'm a Full Stack Developer who cares about good design.

I will design and build a web application that is fast, usable, and accessible. Whether you have a finished design or just an idea, I will design a clear structure and interface. UX is part of my process from the start, and accessibility is a standard, not an afterthought.

Teams I have collaborated with

Testimonials

"I worked with Jan on the development of a frontend tool that was highly specialized for our needs, which also corresponded to the requirements and backend communication, which was not entirely trivial. However, I worked very well with Jan, not only thanks to his precisely executed work, but also thanks to his ability to empathize with the needs of others and ask the right questions. I am happy to meet people like Jan on any project and I can only recommend him."

"As his colleague, I worked with Jan on several projects and he always insisted on top-quality work. Even though he is primarily a developer, he has great overlap and knowledge in the field of UX/UI design. Jan is an ideal candidate for any project, whether it's web application development or another digital product. I recommend Jan and believe that his approach and enthusiasm for work will be beneficial for any team."

"With Jan, I've experienced great cooperation on projects that required senior engagement with time pressure and quality requirements. He is self-driven, strives to excel in all assigned tasks. He works in a team and always makes it a priority to help others succeed when they are struggling. Jan gives attention to details, and his Frontend work output is rich in artistic appeal, aligning with best practices in modern UX/UI. Besides Frontend, the work spectrum covers even backend and db where critical thinking and solid architecture is his main domain. He is an extraordinary employee and team member that fits any team goal."

"Jan and I worked together on several projects. I can recommend him as a senior full stack developer with a sense of design. He is a person you can entrust with a complex project, easily in the order of 100MD, and he will take care of it from start to finish. If you don't use his services, I'll be happy, he'll have more time for me 😊."
