The Story

I didn't get here through a CS degree. I built the foundations with structured courses on freeCodeCamp, Scrimba, Coursera and Udemy, then put them to work right away. The real training was four years of client work: agencies and organizations in Florida and California that needed sites built, maintained, secured and fast.

That work covered the whole stack: React and TypeScript up front, Node.js, PHP and Python behind it, PostgreSQL and MongoDB, and WordPress builds with custom post types and fields for teams that needed to edit their own content. Every engagement added something new — and the industry moved fast. I moved with it.

When the AI revolution hit, I didn't see it as a threat — I saw it as a force multiplier. I decided to bring everything I'd learned together and launch FSEVO: a studio where human experience and artificial intelligence merge to create web products that stand out. It's not AI replacing the developer. It's the developer, evolved.

How We Work

Production Code

TypeScript strict, accessibility, SEO, Core Web Vitals. The standard you'd ship to an enterprise client.

AI as Copilot

We use AI to iterate faster, generate more ideas, and maintain a quality standard impossible to achieve alone. AI amplifies — humans decide.

Obsessive Detail

Micro-interactions, typography, visual rhythm. The details that separate a $29 template from a premium one.

Built to Ship

Every product is production-ready from day one. No placeholders, no Lorem Ipsum, no "finish it later."
