Work with me

An open-source, bilingual (EN/ES) web app that estimates which rent law protects an LA renter — City RSO, AB 1482, LA County RSTPO, or just-cause — from their address, plus the current legal increase cap and a rent-increase legality checker. With no public RSO-registry API to lean on, I designed an 'honest estimator' over live LA County Assessor and US Census open data (cross-verified against the county roll), with a four-regime rules engine that leans protective at every ambiguous boundary and degrades to 'pending — confirm with LAHD' rather than ever being confidently wrong. Locked by 222 tests; a profiled indexed-query fallback cut lookups from 13–55s to ~1s. PageSpeed 100/100/100/100, WCAG AA in light and dark.

A mental health SaaS I designed around Judith Herman's three-stage trauma recovery model. I built AI-guided journaling with a Gemini-powered crisis-detection safety pipeline (GREEN/AMBER/RED) — deliberately fail-closed on input and fail-open on output, validated by an LLM-judge eval harness with zero tolerance for missed crisis cases — plus peer support circles, Stripe billing, and an Android build via Capacitor, solo full-stack across web and mobile.

A real-time OSINT situational-awareness web app styled as an intelligence watch floor. I aggregated 10+ live public feeds (USGS, OpenSky ADS-B, CISA KEV, NASA, GDELT, CelesTrak…) through a config-driven feed registry with server-side caching, and visualized them across four views, including a Three.js 3D globe, a cyber-vulnerability board, and satellite/orbital tracking.
