Senior engineer, 10 years, mostly Rails and React with the last year in Flutter and Node on consumer mobile. I own delivery end to end — client requirements through architecture, release, and iteration — and I mentor the developers around me.

Currently running a multi-tenant consumer mobile platform live in three markets, 90+ business partners and 1,500+ users. Second and third deployments needed no rearchitecture.

Also doing a lot of work on codebases built fast with AI tooling: reading them, finding what's actually broken, and telling the owner what's salvageable. Recent example was a Supabase app where parts of the site weren't gated at all and the permission model let anyone escalate their own access via the API.

Open to full-time or contract.
