Bio
Topher Kanyuga
Jeferson was an excellent developer and an amazing team member. Whether working on client applications, infrastructure or developer tools, I could count on Jeferson to work independently and deliver quality work even in areas/technologies he was unfamiliar with. He was always willing to help out his team and had a great attitude. His suggestions, opinions and questions improved our team's decision making as a whole. We will miss him.
Dan Wash
Jeferson was a great member to have on our team and it was tough seeing him leave. Over his 3+ years at Ceros, he played an integral role in the development of our Studio product. He excelled as a member of his team, always bringing a positive attitude with him and living up to the Ceros core value of giving a shit. We will definitely miss having Jefferson on our team.
