What People Say
Feedback from clients and collaborators I have worked with.
“Sebastian came to us to write a few lines of JavaScript. Today, 60% of our IT solutions run on his code. He built our route system trasy.edk.org.pl from scratch, serving tens of thousands of pilgrims every year. Then came the payment system, charity brick store with warehouse management, and a mobile app with offline maps and compass for night marches. He grew from a small volunteer task into the architect of nearly all our technology. What impresses me most is that he learns whatever is needed and delivers real solutions that serve real people.”
