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.

Built for fun

Hobby projects I design and build on nights and weekends — for the joy of it, and shipped to production for real people to use.

What people say

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

Writing

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

Lately

  1. Nov 6

    Made a same-day reel for a band's surprise EP, clips from all three videos, posted to the feed, the story and TikTok drafts. Release Wave is getting good at turning a drop into a post in an afternoon.

  2. Nov 6

    Countersign is a new idea I'm chasing: an assistant on your phone that does real errands in a browser, and stops to ask before anything that spends money or acts in your name. First build is headed to TestFlight.

  3. Nov 5

    Myne now works properly on the iPhone Duo's outer display, and I've got the next round of under-the-hood upgrades merged and tested on both iPhone and Android.
