Andrew Martin — Full-stack engineer in SF

I build software
with intent & craft.

Developer Experience & AI Platform @ Credit Karma

14 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 2

    Myne Plus is going unlimited on items. I'm also planning how to list one thing on several marketplaces from the app, so selling stops meaning retyping everything.

  2. Oct 2

    Cloudtape 1.1.0 is on its way to TestFlight. It has an Up Next queue, smart playlists, listening stats, and storage limits so downloads don't quietly eat your phone.

  3. Oct 1

    Release Wave's updates page now drafts itself every week. I get a short summary on my phone and tap publish or reject. Nothing goes live without me, but I don't have to write it either.
