Hi, I'm Marek Gregor.
I design software solutions with expertise in both backend and frontend development.

With over 20 years of experience, I’ve grown from a Java expert to a solution architect, designing key systems for IT companies in the energy, industry and finance sectors. I’m driven by the opportunity to keep learning and contributing to impactful tech solutions.

My work for software companies was transformative, bringing them new possibilities and delivering solutions that addressed their market needs. I helped transform decades-long software solutions by introducing new capabilities, such as opening systems to standardized APIs, transitioning from desktop to web-based UIs, running systems on containerization platforms, or introducing new technologies to daily development processes.

My approach to software development is hands-on — I still implement key algorithms and actively contribute to the development process, not just system design. Here are some projects I've worked on.
