Andrew Martin — Full-stack engineer in SF

I build software
with intent & craft.

Developer Experience & AI Platform @ Credit Karma

16 years shipping for scale. I build fast, resilient products and the developer tooling that ships them — now on Credit Karma's AI Platform team, building delivery tooling the org's 1,000 engineers use to ship to 140M+ members. Alongside that, I'm currently taking on contract work — hourly, fractional, or a full project build. Product, websites, and AI tools.

What people say

A few words from people I've built alongside — at Credit Karma, Lyft, and beyond.

Andrew is at his best with an ambiguous problem and no clear path — he investigates, narrows it down, and ships a solution without needing much supervision.”

Writing

Occasional notes on building — AI tooling, developer experience, and the odd deep dive.

Lately

  1. Oct 28

    Working on short talking-head videos for Release Wave. I record myself, and the album art, facts and similar artists show up around me. I want a weekly video habit that doesn't eat my week.

  2. Oct 28

    Cloudtape now copes with huge music libraries. A friend with tens of thousands of songs found it sluggish, so I reworked how it reads them. It's out to beta testers now, with a public link to join.

  3. Oct 27

    Designing a pickleball club tee this week. Small chest print on the front, a big illustrated back, and a dozen colour versions side by side until one feels right. Picking from a board beats guessing.
