Fractional CTO · San Francisco · working remote, worldwide
Every company I've built has done the same thing: hand someone direct access to something that used to be scarce or gatekept — an AI tutor for a kid who didn't have one, an English coach that's available at 2am, a freelance market that matches people instantly instead of the usual gatekept hiring grind. These days that means production AI agent systems and full-stack builds — senior enough to own the architecture, hands-on enough to ship it.
What I can be for you
Your fractional CTO for a technical leader before you can hire one full-time.
Own the technical direction part-time — architecture, the hard build-vs-buy calls, code review, and early hiring. For founders who need senior judgment now, not a full-time salary.
Your AI engineer for production agent systems, not demos.
Multi-step autonomous agents: tool use, orchestration, structured outputs, and eval discipline. Built against Claude and OpenAI in production daily — including the system that wrote this very growth.
Your product engineer for the actual product, shipped.
Next.js 15 / React 19 / TypeScript front to back, Postgres on Supabase, Stripe, auth, the works. From a Figma file to a deployed app on a current, boring-in-the-good-way stack.
Your engineer-in-residence for an inherited codebase that behaves.
Take over a codebase and make it safe and fast: migrations, row-level security, CI gates, and the unglamorous production-incident fixes — plus an honest assessment of what you actually have.
Selected work
Integrations & platform surface owner
A multi-tenant Next.js content platform where I own the machine-facing surface: a 36-tool API generated from a single Zod manifest with capability-scoped auth, reachable over MCP, REST, and an internal CLI. Plus the unglamorous wins — row-level-security hardening flagged by a production advisor, a fail-safe publish path, and a migration-ordering CI gate.
Built the web application
A freelance marketplace with vetted, instant matches. I built the web app front to back — chat, invoicing, escrow, and Stripe payment flows — reaching ~1K monthly users and $40K revenue.
AI education platform
Immersive K–12 education powered by AI: interactive lessons, characters, and personalized journeys — including conversational voice agents, not text-only chat.
Voice-first language tutor
AI-powered business-English learning built around conversational voice practice, with the voice layer built on ElevenLabs.
Some clients are covered by marketplace agreements and aren’t named here. Happy to walk through any of it on a call.
How I work
Every proposal I send names the gaps as clearly as the strengths. You'll never find out mid-project that I was bluffing — the honesty is the whole point, and it's cheaper than the alternative.
The value of a fractional CTO is the decisions you avoid making wrong. I bill for the architecture that saves you a rebuild, not for filling a seat.
I work on what I'd choose for my own product — Next.js 15, React 19, TypeScript, Postgres — so there's nothing to unwind later. This site is built in it.
I do my best work as the person who owns a surface end to end on a small team, close to the founders and the actual users.
Background
I've spent my career as a founding or consulting CTO across five startups — AI education, business-English learning, freelance marketplaces, and a multi-tenant content platform. Since early 2026 I've been hands-on with production AI agent orchestration every day, and I build with these tools constantly — the automated system that surfaced and wrote this growth is my own. I'm based in San Francisco and work remotely with teams anywhere.
