Fractional CTO, interim CTO, and outsourced CTO for AI products, agents, and automation. I own the technical outcome end to end — discovery, architecture, build, deployment, and production — working directly with the product owner. I work as a Forward Deployed Engineer (FDE). That is the difference between me and a CTO-as-a-service arrangement that stops at advice. Most software delivery is not slow because developers type code slowly. It is slow because work waits. A product owner explains the problem to an analyst. The analyst turns it into a spec. A PM coordinates it. A developer builds it. DevOps deploys it. Every handoff is another queue — and another place where context gets lost. A part-time CTO who only advises adds one more queue. I remove them. WHAT A FRACTIONAL CTO ENGAGEMENT LOOKS LIKE WITH ME Discovery → Specification → Architecture → Build → Integration → Deployment → Production ownership. No spec ping-pong. No ticket factory. No one in the middle translating what the product owner meant. You get technical leadership and the working system from the same person. WHAT I BUILD • AI agents and agentic workflows connected to real business systems • Business process and workflow automation • Internal tools and operational software • Document and data processing systems • API, CRM, SaaS, and third-party integrations • AI features inside existing products • Production-ready replacements for AI/vibe-coded prototypes • Cloud infrastructure and deployment around the systems I build WHERE A FRACTIONAL OR INTERIM CTO IS THE RIGHT CALL • You are a non-technical founder and need a technical co-founder profile without giving up equity • Your CTO left and the team needs an interim CTO to hold architecture and delivery • You have an AI initiative and nobody to decide what is real and what is a demo • You need an outsourced CTO to run vendor selection, architecture review, and technical due diligence • You have a prototype and need someone accountable for getting it to production HOW I USE AI AI is not valuable because it types code faster. The bigger advantage is context. Instead of starting every task from a five-line ticket, I use the available product context — requirements, decisions, architecture, previous discussions, constraints, and current system state — to keep implementation connected to the original business problem. Claude Code, MCP, OpenAI, Gemini, and other agentic tools help me cover more ground without splitting the problem across a larger team. The engineering judgment stays human. PRODUCTION, NOT DEMOS Shipping the first version is only part of the job. I also care about: • secure secrets handling • least-privilege access • isolated environments • Dockerized deployments • logging and operational visibility • failure and edge-case handling • maintainable code and documentation • deployment and rollback procedures • a written runbook for whoever owns the system next Stack includes Claude Code, MCP, OpenAI, Gemini, AWS, GCP, Azure, DigitalOcean, Docker, Tailscale, Cloudflare Tunnel, and WireGuard. WHEN THIS WORKS BEST The best engagement starts with one bounded product or business workflow and one person on your side who can make product decisions. Give me direct access to the problem, the relevant systems, and the person who owns the outcome. I take it from there. WHEN I AM NOT THE RIGHT FIT If your real bottleneck is five mandatory departmental approvals, adding a faster engineer will not solve it. If nobody owns the product and every decision still needs a committee, a fractional CTO will end up waiting in the same queues as everyone else. I would rather identify that before we start. If you have a product, internal system, AI initiative, or workflow that moves much slower than it should, send me a message describing: 1. What needs to happen 2. Who currently touches it 3. Where it usually gets stuck I'll tell you whether it is a good FDE-shaped problem and what I would carve out as the first production scope.
