Case studies.

Four production systems, written up the way engineers actually want to read them — architecture, internals, war stories, and the real numbers behind each one.

Trevion

Personal Project

A self-hosted AI life OS that replaces 12+ disconnected apps with one private brain — voice, web, and desktop — and autonomously develops itself via a 24-agent build org with auto-reverting gates and a merge train.

LeadForge

Live

A self-optimizing outbound pipeline that replaces a full-time SDR and $300–500/month in tooling — 40 free-source scrapers, a quality-weighted bandit, zero-cost SMTP enrichment, and an 11-intent reply loop. Humans approve every send.

ToCoach

Personal Project

A local-first Electron sales coach that replaces $1,500–4,000/month of human coaching with on-demand voice role-plays against AI buyer personas — on-device Whisper + Kokoro, and an accountability engine that locks features if you skip practice.
