I’ve had the privilege of working with Janis for more than ten years, and for the last four—after I became a manager—he has been part of my team. As a member of our agile Scrum team, Janis quickly established himself as a highly respected colleague and a valued point of contact both within and beyond the team. His profound knowledge has supported us in many situations, and his commitment to sharing expertise through regular knowledge transfers has been a great benefit to the entire group. Janis is well known as our security champion, where his expertise and dedication have significantly strengthened the team’s capabilities. He consistently delivered high-quality results, stayed reliable even under changing conditions, and adapted smoothly when focus or direction shifted. What impresses me most is Janis’s drive for continuous development. He demonstrates the functional skills needed for his role at a very high level, while also showing initiative and willingness to keep growing professionally. This combination of knowledge, reliability, and dedication has made him an invaluable contributor and a trusted colleague. I can fully recommend Janis as a skilled, dependable, and forward-looking professional who brings great value to every team he is part of.
It is rare to have such a dedicated and professional software developer in your team. Janis is able to learn new topics and technologies very quickly, analyse them and implement them very accurately. A high level of passion, energy, drive and out-of-the-box thinking describes Janis quite well. It is more then fun to work with Janis - it is a honor - not only because of his positive attitude and motivation. For sure he would be an asset for each company looking for a competent Software Engineer and teamplayer.
Janis is an outstanding professional with deep expertise in security. He was like a mentor to me, always willing to share his knowledge and guidance.
