Full-stack engineer, B.S. Math-CS from UC San Diego

I build and run GratMap (https://gratmap.com) a live production web app I designed, built, secured, deployed, and operate solo. React + Mapbox front end, Express/Node + MariaDB back end, on a Linux server I administer myself. Two parts I'd point at: a venue-scoring pipeline that shrinks each venue's median toward the global median in proportion to how much data it has, so a two-report venue can't outrank a two-hundred-report one; and a pre-launch security audit checking for breached-password screening via HIBP k-anonymity, rate limiting, JWT in httpOnly/sameSite cookies, ORM parameterization.

Before that I was the founding engineer at Citmit, a construction-permitting SaaS startup. I joined when they had a product plan and no engineers, built the initial codebase and infrastructure from scratch, and led a team of four through alpha. I implemented Stripe billing, an S3 document pipeline, and the application-side integration for their LLM feature.

I work in Claude Code every day and can explain and debug what comes out of it without it.

Looking for: full-stack product engineering
