Full-stack engineer, B.S. Math-CS from UC San Diego. 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 engineers through alpha. I integrated Stripe billing, and S3 document pipeline, and the application side integration for their llm feature. Since then I've built and run GratMap (https://gratmap.com), a live web app where service workers share and discover tip earnings on an interactive map. React + Mapbox frontend, Express/Node+MariaDB backend, on a Linux server I administer myself. I designed, built, secured, and deployed it, and I've been the only person on call for it since its July launch. Venue scores shrink toward the global median in proportion to how much data each venue has, then map to a tie-aware percentile, so a 2 report venue can't outrank a 200 report one. I ran the security audit before launch. breached-password screening via HIBP k-anonymity, rate limiting, JWT in httpsOnly/sameSite cookies, ORM parameterization. I work in Claude Code every day and can explain and debug what comes out of it. Looking for: full-stack product engineer or founding engineer roles

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
