{About}
15 years in IT. Every role, every perspective.
Over 15 years in IT I've walked the full path: from tester, through analyst and project manager, to developer. That lets me see a project from every angle at once - business, technical and the user's.
With me there's no anonymous team and no sales department. You know exactly who analyses your needs, who writes the code and who is accountable for the result. I know which questions to ask, how to design a solution that won't fall apart at the first change of requirements, and how to carry a project across the finish line. No excuses - get it done.

Frequently asked questions
Everything worth knowing before we start working together. Can't find your answer? Drop me a line.
The cost depends on the project scope. A simple website starts at a few thousand PLN, an online store or MVP application from a dozen or so thousand, while complex CRM/ERP systems are quoted individually after a requirements analysis. I always start with a free consultation and a concrete quote - no hidden costs.
