Hands-on fractional CTO for funded early-stage startups

Build faster. De-risk the roadmap. Scale with confidence.

I partner directly with founders and technical leaders to improve engineering velocity, implement practical AI workflows, and ship production-grade products from zero-to-one through PMF.

Proof

Proof, not promises

Recent engagements focused on startup velocity, practical AI enablement, and measurable execution outcomes.

HIPAA Mobile Product Delivery

Challenge: A healthcare client needed a secure iPad app to capture dental history with strict compliance requirements.

Outcome: Delivered end-to-end in ~2 months: requirements, architecture, build, and production-ready handoff.

AI Enablement Across Engineering + Support

Challenge: A startup needed faster delivery and a practical AI operating model across teams.

Outcome: Engineering delivery speed and code quality improved significantly; AI support flows reduced inbound calls by ~50%.

Zero-to-One Team Velocity

Challenge: A new startup needed product execution from scratch with an architecture that could scale.

Outcome: Built a modern stack and AI-enabled team workflow, enabling feature delivery in days instead of weeks.

About

Operator-level CTO leadership

I work directly with founders and technical leaders to close the gap between product intent and engineering execution.

How I operate

I’m a hands-on fractional CTO. I don’t sit above the work — I work inside the product and engineering system to improve velocity, quality, and decision clarity.

My focus is funded early-stage startups that need momentum: tighter execution loops, AI-enabled workflows, and scalable technical foundations.
