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.
