Senior Technology Leader

Shipping software faster with agentic development.

I help engineering teams adopt Claude Code, Codex, Copilot, and OpenClaw to multiply output without sacrificing quality. Executive, lead, and hands-on roles.

About

I'm a senior technology leader and developer with experience spanning executive, lead, and individual contributor roles. I've built and led engineering organizations, shipped production systems, and stayed close to the code throughout.

My current focus is agentic-enabled software development — integrating tools like Claude Code, Codex, GitHub Copilot, and OpenClaw into engineering workflows to accelerate delivery, reduce toil, and raise the quality bar.

What I focus on

Agentic development adoption

Rolling out AI coding agents into real engineering orgs — tooling, guardrails, evaluation, and the culture change needed to make it stick.

Engineering leadership

Building and scaling engineering teams. Technical strategy, hiring, delivery cadence, and the systems leaders use to stay effective.

Hands-on architecture

Software architecture and implementation for web, data, and platform systems. I still ship code — and I review the diff.

Consulting

I take on selective consulting engagements focused on helping teams adopt agentic development practices. Typical work includes:

  • Agentic tooling pilots and rollouts (Claude Code, Codex, Copilot, OpenClaw)
  • Engineering productivity and developer experience reviews
  • Technical due diligence and architecture assessments
  • Fractional engineering leadership

Short and long engagements. Remote-friendly. Reach out to discuss fit.
