You can read here some of the recent testimonials about my consulting work.

Within the last 10 years we have worked with many Developers, Consultants and Programmers but I have to state, that the PIWIK project handled by Maciej was the most enjoyable, productive and time-efficient in all these years. He is very productive, professional and always has a helping hand for its client which makes such cooperation to a real pleasure. I have therefore, no hesitation of recommending Maciej´s Consulting Services.

We contracted Maciej out for custom plugin development, application modification and consultation. He clearly showed mastery in his knowledge of piwik and provided the requested deliverables on time and within budget. He was able to comfortably traverse our internal corporate network, cooperate with our legal and business department and work in an unfamiliar environment. Our architecture includes F5 loadbalacing which makes it challenging to get the type of results we were asking for. Maciej went above and beyond to accommodate these obstacles as well as provide excellent training and documentation to our team.

I would highly recommend him to any large global enterprise in need of a contractor for Piwik – the BEST open source alternative to Google Urchin.
