Full-Stack Developer

Self-Taught. Battle-Tested. Ships Daily.

From GED to full-stack in 3 months using AI as my development partner. I've built 20+ production workers, a valuation engine published on npm, and platforms generating real revenue. Now I help teams ship faster.

How I Got Here

No CS degree. No bootcamp. Just relentless building with AI as my teacher.

The False Start

Tried learning to code with ChatGPT. Built stuff that looked right but broke in production. Fiverr devs wanted $5K for what I envisioned. I knew there had to be a better way.

The Pivot

Launched my first real website. Started blogging. Discovered Claude + Cursor combo. Suddenly, the code actually worked. Started shipping daily.

The Explosion

3 months of building every single day. Workers, APIs, CRM systems, valuation engines, dashboards. Publicly challenged Opendoor — they saw it, stayed silent. So I open-sourced my alternative.

"We challenged Opendoor to explain their algorithm. Someone from their corporate pricing team viewed our post. Complete silence. So we reverse-engineered it ourselves."

— The moment I knew transparency was the edge

AI as Co-Founder

Claude isn't my autocomplete — it's my technical co-founder. Every error is a lesson. Every build gets faster. I ship in days what used to take months.

Transparency Wins

While competitors hide their algorithms, I publish mine. Open-source valuation engine. Consumer protection tools. The opposite of iBuyer playbooks.

Production Systems

Real infrastructure handling real users and real money.

Opendoor Algorithm Reverse-Engineering

Publicly challenged Opendoor to explain their pricing. They viewed our post, stayed silent. So I deconstructed their methodology — exposed hidden fees (8-13% effective vs 5-8% advertised), inflated repair credits, and secret market adjustments. Built a transparent alternative and published it as an npm package.
