Engineering leadership for teams building with AI.

Twenty-five years building software and the teams behind it, at Thoughtworks, Groupon, Angie's List, Centro, Tempus AI and Pinger. Today I work with founders and engineering leaders as a fractional CTO, advisor or hands-on builder, and I build my own products, starting with Idynic.

Issues go in, reviewed pull requests come out. Every row is a real build by the agent pipeline I run, with what it cost and how many tries it took.

How I help

Fractional CTO / VP Engineering

Part-time technical leadership: strategy, hiring, architecture and delivery, two to three days a week.

Best for: Series A-C startups scaling from 5 to 50 engineers

Technical Advisory

Regular sessions with founders and engineering leaders on the decisions that shape the team and the platform.

Best for: Founders and eng leaders navigating critical inflection points

Project Consulting

Time-boxed engagements on one hard problem: an AI integration, a migration, a delivery bottleneck.

Best for: Teams facing a specific technical challenge with a deadline

Now building

Products and platforms I'm building at the intersection of engineering and entrepreneurship.

Everything I've built →
Idynic

Founder

Active

product

An AI career-identity platform. It turns a work history into an evidence-backed profile, then generates tailored résumés, cover letters and recruiter-facing pages from it. Solo-built, and this site runs on it.

Active

service

A youth fitness business I co-own, where I run program operations, curriculum and customer experience.

This site is generated live from my Idynic profile.

What Clients Say

A few words from the people I've had the privilege of building with.

AI application development

Jeff has been an invaluable technical partner. The AI-powered tools he built helped us demonstrate real-world value to customers faster than I thought possible. He understands the sales cycle and delivers production-quality software on startup timelines.

Custom platform development

I came to Jeff with a messy set of manual workflows and walked away with a platform that actually runs my business. He asked the right questions, moved fast, and built something my team adopted immediately. Worth every dollar.

Fractional engineering leadership

Jeff joined us as a fractional technical lead at a critical moment — we were under deadline pressure to deliver a government proposal platform and needed someone who could architect it right and get it across the finish line. He did both, and the quality of the work gave us real credibility with our first clients.

CEO · GovTech Startup

AI advisory

Jeff has been an indispensable AI advisor for our team. He cuts through the noise and keeps us oriented on what actually matters in the AI ecosystem — the right tools, the right timing, and how it all applies to our business. His guidance has shaped how we think about our product roadmap.
