📣 What people say

• Sedhu was the founding engineer at Cypher and grew into the role of Head of Engineering. He played a central role in building the technology foundation that enabled Cypher to process more than $100 million in annual transaction volume.

  Sedhu consistently demonstrated a strong sense of ownership, from solving complex technical challenges to helping scale the engineering organization. I would highly recommend him to anyone building an early-stage engineering team or looking for a technical leader who can build from the ground up.

• Sedhuraja is a highly talented professional in the industry. He is keen to learn new techs and apply them in his day-to-day work. He is very committed. He is one of that people, to whom you can give a new challenge, and he will be ready to accept it with a smile. He is a very energetic and compassionate person to work with. I would definitely recommend Sedhu for any team or organization. He will be an asset to any organization.
