Over the years at Navan, I witnessed Tansel's exceptional craftsmanship and design acumen, particularly in translating product vision into user-centric designs for Trains, Rental Cars, and Black Cars lines of business. His attention to detail, user feedback incorporation, and strong communication skills ensured seamless collaboration across teams.

Tansel's leadership and dedication were invaluable during significant team changes, fostering a collaborative environment and high efficiency. I genuinely enjoyed working alongside him; his positive energy and creative approach made every project a pleasure.

Tansel has been more than just a colleague—he’s been a trusted partner, and I have no doubt he will bring the same level of excellence and warmth to any organization he joins.

I had the opportunity to work closely with Tansel on our Trains product, and I was consistently impressed by the level of thought, care, and ownership he brought to every aspect of the design process. Tansel has a strong work ethic and an exceptional ability to balance user empathy with business needs—something that truly set him apart on a product as complex and operationally nuanced as Trains.

 

He consistently advocated for the user while deeply understanding the constraints and goals of the business, which made him a trusted partner across Product, Engineering, and Ops. Any team would be lucky to have him on board.

Working with Tansel at Navan has been one of the highlights of my time here. Although we focused on different areas—him leading design for cars and trains, and me for flights—our collaboration quickly turned into a kind of mentorship. His depth of product thinking, sharp attention to detail, and years of design experience consistently pushed my work to a higher standard. Beyond being a talented designer, he’s a natural leader— calm, thoughtful, and generous with his time. I’ve learned so much from him and feel lucky to have worked alongside him.
