About Me

I specialize in AI-augmented engineering — developer workflows where AI agents enforce code quality, scaffold tests, and orchestrate CI. Formally titled Frontend Engineer at Even Labs, I now work at Software Engineering scope — owning testing and CI architecture, shipping product features, and stewarding the team's shared AI agent system — and I treat AI agents as collaborators inside the workflow, not shortcuts around it.

At Even Labs I work on a music distribution platform built on a Turborepo monorepo, owning the testing and continuous-integration backbone the rest of the team depends on. The Experience section below traces the specific shipped work — pipeline rewrite, monorepo testing foundation, dependency hygiene, and the shared rulesync agent system that other engineers now actively maintain alongside me.

I run a production-grade homelab — Proxmox (9 LXCs, 2 VMs), ZFS storage, Ansible-managed infrastructure, and Cloudflare tunnels — the same operational discipline I apply to production code.
