Barış Deniz Sağlam

I'm a senior AI engineer and PhD researcher. For six-plus years I've designed and shipped production AI systems — owning architecture, system design, and tech-stack decisions across health tech, insurance, legal tech, and aerospace. Now I'm focused on research — foundation models, continual learning, and neuro-symbolic AI.
