I spent five years in IT support keeping office systems, networks, and hardware alive the kind of job where you learn what "production is down" feels like before you ever write a line of application code. In 2022 I retrained as a JavaScript developer, and since then I've been building web apps the way I used to keep systems running: measure first, type everything, assume things will fail.
In 2025 I founded PrismaFlux Media, my own studio, where I build and ship client projects end to end: schema design, API routes, auth, payments, deployment.
I don't list metrics I can't reproduce. Run the Lighthouse reports yourself:

Next.js (App Router) React 19 TypeScript Drizzle ORM Neon Clerk Stripe
The full e-commerce loop, built independently: catalog, cart, Stripe Checkout. I designed the database schema, wrote the API routes for cart logic and payment webhooks, and wired up Clerk auth. The parts I'm most proud of are the boring ones idempotent webhook handlers and integer-cent pricing, because payment code is where float bugs go to ruin your week.
Next.js React TypeScript Drizzle ORM Neon PostgreSQL
A brand website for a local family winery, built and launched end to end through PrismaFlux Media and deployed on Vercel in July 2026. Real client, real deadline, real content.
My studio's own site. I migrated it off WordPress/Hostinger onto Next.js and Vercel, including the full DNS move across Cloudflare and Hostinger the blog has write-ups on how I work.

- 100ms or explain yourself — interactions slower than that need a transition or an optimization.
- Types are documentation — if it isn't typed, it's a liability someone inherits.
- Ship lean — Server Components over client JS, Biome over ESLint, measure before optimizing.
