Full Stack Developer

Hi, I'm Jack. I build beautiful software that performs as well as it looks.

I'm a full-stack engineer with eight years building SaaS platforms, startup products, and scalable web applications — from first commit to production at scale.

(01) About

A design-minded developer obsessed with performance, clean architecture and user experience.

For the past eight years I've helped startups and product teams turn ambitious ideas into software people genuinely like to use. I care about the whole stack — the database query, the API contract, the animation curve.

My work sits at the intersection of engineering and design: fast, accessible, and quietly considered. No fireworks, just products that feel right.

Frequently asked.

Startups, scale-ups, founders, and product teams who value craft over noise and want a partner who sweats the details.

Mostly React, Next.js and TypeScript on the front end, with Node.js and Go powering the back end — plus Postgres and AWS.

Anywhere from a focused two-week sprint to a multi-month build. We scope it together honestly up front, with no surprises.

Always. I've collaborated with teams across twelve time zones and keep communication tight, async, and documented.
