Full-Stack Developer

I ship fast, scalable products with a focus on performance.

I build high-performance web applications using Next.js, React, and modern backend APIs. With nearly two decades of experience, I help startups and businesses ship scalable SaaS products, dashboards, and integrations that are fast, secure, and easy to maintain.

About

Two decades of shipping the web.

I've spent nearly twenty years across product companies and independent consulting — from large enterprise teams to lean startups — always close to the code and the people using it.

My focus is performance and scale: SaaS platforms, internal dashboards, headless-CMS marketing sites, and the integrations that hold them together. I care about applications that stay fast, secure, and easy to maintain long after launch.

Today I work in an AI-assisted flow — Cursor and Claude are part of my daily toolkit — which lets me move quickly without trading away the craft. Less ceremony, more shipping.
