“Uysim is a great colleague to have. Humble, energetic and extremely dependable, he owns his work, understands what matters and knows what to work on next, asking questions as needed, not sitting and waiting to be told what to do. Not being a native English speaker didn’t get in the way of him sharing important ideas and insights and becoming a dear member of the Passbase team. At Passbase, Uysim was a core maintainer of our Ruby on Rails backend, handling features, support and app security. He also worked with Product on the cost and potential return of different initiatives, playing directly into product prioritization. As a highlight, Uysim helped us switch facial recognition vendors, leading to improvements on reliability and over $100k/year in cost savings. Highly recommended!”
