Notes from collaborators

“I've been most impressed by his exceptional ability to tackle every phase of software development with in-depth knowledge, confidence and clear communication. I cannot emphasize enough how good Selcuk is at communicating in a clear and structured manner.”

Daniel VliegenthartTeam Lead, Tellimer

“He was the perfect remote contractor in many ways. His communication skills are top, he is very much a self-starter who can get stuck in on work with minimal guidance or oversight, and his code quality (and documentation!) is exceptional.”

Ian WattCo-founder, Tellimer

“Selçuk is a quick learner, he approaches problems systematically and understands the business and customer needs. He is very detail-oriented, and a hard worker. You can trust him with the most challenging issues.”

Erdem KurulSoftware Development Manager, Intertech

“I had the pleasure to manage and to work with Selcuk Cihan for the past 2 years while at Tellimer. He rose brilliantly to all challenges thrown at him both technically and communication wise. I would say his superpower is his communications skills, both writing and talking.”

Decebal DobricaSoftware Architect, Tellimer
