Senior full-stack Java and AngularJS developer
With no exaggeration I can say that Illya is flat-out amazing. Excellent developer, an expert in his field. But also a great communicator, and super bright problem-solver. Always understanding the exact problem and getting it solved better and faster than anyone had even hoped for. This is how doing software development should be!
