Work History & Feedback

Development Services Setup (Build Engineer)

“Ratn is an excellent engineer. He has a very diverse set of skills and picks up new technologies quickly. For Dachis Group he handled projects on everything from system integrations to web UI development. He was one of those great luxuries. You could give him a high level description of the problem you needed to solve or the enhancement you needed to make and he would simply take care of it. You didn't need to over specify you didn't need to micro-manage. He would simply take care of it. Ratna also has a keen grasp of agile methodology and infrastructure. He became a key part of our DevOps strategy group. Ratn is a rare find. Extremely smart. Good communication skills. A great guy to work with”
