CTO · Technical Co-Founder · Builder
I help founders turn ideas into products that ship, scale, and sell.
You have the vision. You need someone who can architect the system,
hire the first engineers, choose the stack, and ship v1 — fast.
That's what I do.
🏗️ Architecture & Execution — I design systems from day zero: data models, APIs, infra, CI/CD. No over-engineering, no tech debt time bombs. Ship fast, refactor when it matters.
👥 Hiring & Team Building — I've built engineering teams from scratch. I know how to write the job spec, screen for signal, and create a culture where good engineers stay.
📊 Product Thinking — I don't just write code. I ask why before how. Features get built because they move a metric, not because they sound cool in a standup.
⚡ Speed to Market — Startups die from slowness, not from imperfect code. I optimize for learning velocity: build → measure → iterate. Weeks, not quarters.
| Fractional CTO | Part-time technical leadership for early-stage startups. Strategy, architecture, team oversight. |
| Technical Co-Founder | Deep partnership from zero to one. Equity-aligned. I build the product while you build the business. |
| Build Sprint | Intensive 4–8 week engagement to ship an MVP or rebuild a critical system. |
| Due Diligence | Technical audits for investors or acquirers. Stack assessment, team evaluation, risk mapping. |
