          MARTIN VO
          CTO

          In my career, I've met lots of developers who were either perfectionists - lost in the pursuit of their never-ending satisfaction from their code, or developers who take the shortest way to the solution without thinking a step further about the real-world problems which might occur. Jan is the best developer and leader I've worked with, who has also found the perfect balance between these two poles.

          CHALER DAVIES
          PRODUCT MANAGER

          Jan's highly organised, hard working, and understands new problems very quickly. He has a strong product sense, and his output was always high quality. I enjoyed working with him a lot, and would love to work with him again in the future.

          ANDY DONE
          CO-FOUNDER

          Jan's highly professional, well organised and structured and his Python code is of a high standard
