Ali Cagatay
AI Engineer · Software Builder · Founder
I build and ship products from scratch - from AI systems to full-stack software. I currently work as an AI Engineering & Research Lead at Kollestee UK Global, where I lead research and development efforts and am building Follicle Labeller, a medical imaging and annotation tool used to detect hair follicles and grafts on the human scalp. Previously, I worked as a Software Engineer and Machine Learning Engineer across startups and mid-sized companies, while earning a BSc in Computer Science and an MSc in Artificial Intelligence. Outside of work, I build and ship my own tools that help me work much faster and more efficiently.
