I build production ML, LLM systems, and AI agents for semiconductor engineering at Samsung Electronics. Before that, my Ph.D. in aerospace engineering focused on flight control, guidance, and optimization for UAVs. The common thread is reliable decisions for complex physical systems under uncertainty.
