I build
Founder of PlainLegal.net — reached 1,000 paying users in 150 days. I design and ship production-ready systems combining React/TypeScript frontends, Python/Django backends, and interpretable machine learning. Currently developing EMRA — an interpretable ML framework for early metabolic risk detection using nationally representative health data (NHANES).

About Me
Building Interpretable Systems That Work in the Real World
I build applied AI systems and production-grade web products with a strong emphasis on clarity, interpretability, and structured execution.
My background combines:
• 12+ years in judicial systems (process rigor, documentation discipline, regulatory awareness)
• SaaS product development (1,000+ paying users)
• Applied machine learning research (interpretable ML on population health data)
I operate at the intersection of engineering, structured thinking, and real-world deployment — designing systems that are not only functional, but explainable and reliable.
What I ship
React/TypeScript UIs; Django APIs; Stripe; PostgreSQL; CI/CD
