Andrew Higgins

Full-stack engineer at Moat — Flutter, Go, PostgreSQL. Computer Engineering at BYU, class of 2028. Provo, Utah.

I care about the unglamorous parts: clean data models, deploys that don't break, and CI that catches the mistake before a customer does.


What I'm doing now

Moat · Full-stack engineer and team lead, Jan 2026 – present Asset intelligence for facilities teams — preventative maintenance, warranty readiness, capital planning. Roughly 190 pull requests merged across Flutter, Go, SQL and CI. Built the QR-coded asset onboarding pipeline that every live customer uses, a bulk CSV import path with row-level validation so enterprises can load a whole building portfolio in one upload, and an AI classification and replacement-cost system that backfilled 12,400+ assets. Wrote a migration-ordering guard into CI after a near miss in production; it has blocked 140 bad migrations since August.

Beehive Digital Solutions · Founder, 2026 – present Websites for small Utah businesses. Three paying clients live. A reusable template, a CMS the owners actually use without touching code, and I run the domains, deploys and hosting.

BYU Formula SAE Electric · Electronics and firmware lead, 2025 – 2026 Led four engineers building a from-scratch control board to replace the legacy electronics on the team's electric race car.


Projects here

Project Atlas Four-layer STM32G474 control board for the FSAE electric car. Three independent FDCAN buses, six switched power outputs, USB-C debug. Full manufacturing package released.
migration-guard Go CLI that fails CI when a branch adds a database migration that doesn't sort above the base branch. Ships as a GitHub Action.
Write That Down Flutter app for chatting with an LLM, switching into turn-based voice mode, and capturing structured idea tiles on-device.
Music Mood AI Reads a song's tempo, key, timbre and dynamics with Librosa, turns that into a mood prompt, and generates matching album art.
Beehive site proposals Static site proposals built for local Utah businesses.
