12 years of professional experience in software development (web, desktop and mobile), great communication skills and ability to roll things out quickly in a step-by-step manner.
Marek is the best employee/contractor I have ever dealt with. His response to requests is prompt, he never seems to meet a problem he can't solve and his solutions are ingenious. He thoroughly tests and debugs problems, makes great suggestions for improvements. He has great work ethic and integrity. I would be more then happy to provide anyone interested in hiring him a more detailed recommendation

Tried to go back to a full-time job, but it did not work. Freelancing is what I'm really good at.
