About Rethina kumar Sukumar
Currently, I am a Senior Consultant in Database at S&I Systems Pte Ltd. My past positions include Database Systems Engineer and Presale Consultant at ECS Computers Asia and Database Administrator at NCS group.
Creative problem-solving is what I enjoy the most; I look at it like a serious game. You have the chance to question, rediscover and find out how to approach the same situation from another angle. This way, the product is about quality, not quantity.
I am a passionate reader, explorer, traveler and minimalist. I enjoy the process as much as the result
