Professional Experience

Founder & Principal Engineer

Tuner Logic (tunerlogic.com) | Remote

07/2025 - Present

Founded and launched Tuner Logic, an AI-assisted SaaS platform for automotive performance tuning; sole architect from concept through public launch, shipping ~1,000 commits across 350+ pull requests in the first year.
Architected the full stack — React 18/TypeScript front end, Cloudflare Workers backend (Hono, Drizzle, D1, R2) — including a binary calibration editor with 2D/3D table views and revision diffs, plus a multi-channel telemetry analysis engine.
Built an LLM assistant with function calling grounded in live application data, including server-side provider proxying (Anthropic, OpenAI), usage-metered credit billing via Stripe, and nightly automated model evaluations.
Applied ISO 26262-inspired safety practices: per-component ASIL classifications driving ratcheting test-coverage gates toward 100% across unit, integration, and E2E suites.
Built continuous delivery on GitHub Actions and Cloudflare with per-PR preview environments, sharded Playwright E2E, and recurring security audits.
Engineered a multi-agent AI development platform — coding agents orchestrated across isolated git worktrees on self-hosted runners, with an AI code reviewer as a required merge gate — sustaining multi-team throughput solo.
