What I build

Everything you need to get to launch.

Whether you have a pitch deck, a Figma file or a half-built product, I'll turn it into software your users can rely on, and set it up so it keeps working as you grow.

Why BNCHMRK

Agency-quality work, without the agency.

You talk to the engineer

No account managers or hand-offs. The person on the call is the person writing your code.

Weeks, not quarters

Small scopes, daily progress and a working build you can click from the first week.

Fixed, honest pricing

A clear quote up front. If the scope changes, you'll know the cost before any work starts.

Built to hand over

Clean, documented TypeScript and your own accounts, so a future team can pick it up without starting again.

About

Hi, I'm Nathan.

I'm a full stack engineer and technical lead. I've spent twelve years building the systems behind products people rely on: APIs, infrastructure, data pipelines and the apps on top of them.

I've done agency work for household-name brands and led the ground-up rebuild of a startup's core platform. Since 2024 I've worked directly with founders and small teams through BNCHMRK.

I'm at my best taking a feature from rough idea to production without hand-holding. I use modern tooling, AI-assisted development included, to move faster, but it supports good judgement rather than replacing it.
