Work

How I rebuilt a Tanzania-based operator's web presence as a marketing site and a real back-office, with Claude wired into the workflows that actually matter.

One calibrated model behind every surface, and a chat agent whose first rule is to never invent a number.

A hearing-aware audio platform that measures your hearing with and without earplugs, then filters your music to match, built on a Redis-free Postgres job queue.

A medallion pipeline on AWS (Bronze, Silver, Gold) that cut query latency 16× and data scanned by more than 200,000×, built as a graduate capstone with the trade-offs made explicit.

A ten-year analysis of Seattle crisis contacts that found CIT-trained officers use more force, not less, and a careful account of what that does and does not mean.

An agentic loan-origination system where a deterministic rules engine has final say on every credit decision, and every decision is cryptographically tied to the inputs that produced it.
