Semih Caglar

Founding Engineer & Software Engineering Researcher

Ankara, Türkiye

I'm a Computer Science student at Bilkent University, ranked 1st in my department, a Founding Engineer at Hansel, and an informatics olympiad medalist. I research developer productivity and automated software engineering at Bilsen, and previously worked on agent personalization under the supervision of Prof. Foutse Khomh at the SWAT Lab, Polytechnique Montréal. My work spans automated code review tooling, indoor mapping and route generation, robotics path planning, and applied machine learning, with results published at venues including ASE, EASE, FSE/AIware, and ATIQSER.

"Knowledge is power."

And I'm a powerlifter!
