Andrew at the edge of a lake at dusk

A senior engineer for the hours your team doesn't have.

I'm Andrew Klingelhofer. After 10+ years at companies like Verkada and Uber, I take on a few small projects a year for founders and small teams.

Tell me what you're building Replies within a day. No pitch deck required.

Three ways to bring me in.

Most teams start with one and drift into another. Whatever the shape, you get the same person and a written estimate before anything over two hours.

A project

Build the thing

An MVP, a feature, or a tricky integration. You bring the idea; I write the code and hand it back working.

Like: a payments integration that stops double-charging
A retainer

Keep it healthy

A few hours a month of fixes, upgrades and small improvements, for teams without a full-time engineer.

Like: dependency upgrades and the bug list, every month
A conversation

Think it through

Not sure what to build, or whether an agency quote makes sense? Pay for a call before you commit.

Like: a second opinion on a rewrite proposal

A few sentences about what you're working on is plenty. I'll reply within a day, and tell you honestly if I'm not the right fit.
