§01 — About Me

Any stack.Every layer.

From the server to the screen,built, shipped and kept running.

I'm Heiner - I build web apps from database schema to deploy button. Whether it's a Laravel monolith, a Next.js app with server components, or a Nuxt-powered storefront, I own the full picture.

My toolkit centers on Laravel, Next.js, Nuxt, and Express.js - I pick the right tool for the problem, not the hype.

Currently open to freelance work, internships, or full-time roles where I can build products that matter.
