AI/ML Engineer · Applied AI
MS Business Analytics & AI @ Johns Hopkins (2026) · Washington, DC
I build ML systems that touch real data — from neural inference on cosmological survey data to LLM fine-tuning, multi-agent systems, and full-stack data pipelines. Operator-tested before grad school: I scaled a distribution business 150% with Python automation and cut 10 hrs/week of manual reporting.
