01 — About

Engineer who cares about the boring fundamentals.

I've spent the last four years shipping web products end‑to‑end — from messy legacy CMS revamps to peer‑to‑peer video apps. The thread that runs through all of it is a stubborn focus on the unsexy parts: rendering strategy, build pipelines, image budgets, error boundaries.

Most of my recent work sits at the intersection of Next.js, TypeScript and DevOps — where small modeling decisions and tight feedback loops compound into shippable speed.

The toolbelt.

A mix of what I reach for daily and what I trust in production. New tools earn their place by removing real pain, not by being shiny.
