Your Next Hire Won't Fix Your Shipping Problem
You'll Be In Good Company
How I 2x Your Team
You're hiring devs to keep up. Your competitors are shipping with half the team.
You're investing in AI tools. Your backlog hasn't budged.
You need a CTO's judgment but not a CTO's salary.
Most Teams Today
- More devs hired, same shipping speed
- Senior engineers buried in code review
- Architecture decisions made by whoever's loudest
- Backlog grows faster than the team
Your Team With Me
- AI agents write features, with guardrails I design
- Code review restructured — your team reviews intent, not typos
- Architecture decisions backed by 50+ product launches
- A 90-day rollout plan — not a generic AI tools pitch
Predictable cost. Measurable output.
