Stanko Kostic

It was great working together with Chathura. He was nothing short of a professional, and making everyone's life easier at BOTS tech department. Communication was smooth and efficient, and he helped us create a good build system.

Hamed Babaeian

Working with Chathura is quite enjoyable. Friendly, easy to communicate with and result-driven mindset. He showed on multiple occasions that he's able to pick up on a problem fast with minimum details provided and present optimum solutions to them in timely manner.
