AI-First Transformation Consultant. I help engineering organizations stop using AI tools and start running an Agentic Operating System.
I'm a Head of Engineering with 20+ years across VP Engineering, CTO, Architect and Principal Engineer roles, and an implementor of agentic OS methodology. I also take fractional engagements where that fit makes sense. The same kernel I use with clients is open source — pieces of it are below.

Chat with my AI Twin • YouTube @Control-The-Outcome • Data Reaktor
Production agentic operating systems for engineering organizations: a small, opinionated kernel; digital twins of the principals who actually move the business; a runtime with humans in the loop; and a measurement loop for Rate of Improvement.
The methodology is open. The work is hands-on.
| Repo | What it is |
|---|---|
🧠 agent-kernel | The methodology — four-file twin contract, skill catalog, twin-builder source mirror |
🧬 digital-twin-filip | The reference twin: one principal (me), four role bindings |
🏭 agent-factory | The runtime — loads kernel packages with HITL governance + audit |
📊 agent-roi-generator | ROI calculator + readiness scorecard for prospective twin engagements |
📈 operational-intelligence-lab | Rate-of-Improvement tracker for deployed twins |
🗺 agentic-playbook | The audience-routed map of everything above |
🤝 agent-ready-cto | The catalog — fixed-scope fractional-CTO capabilities, priced and structured for AI agents to discover and route requests to, with a real human always on the other end |
If you don't know where to start, agentic-playbook is the front door.
This profile is built to be read by agents, not just people. agent-ready-cto is the machine-legible version of my fractional-CTO practice: capability specs, pricing, turnaround, and verification requirements, structured for an AI agent acting on someone else's behalf to parse directly.
- 📄
llms.txt— structured entry point for LLMs - 🪪
agent-card.json— A2A-protocol-compatible agent card - 📋
capabilities.json— full capability catalog, machine-readable - 🌐 Human-readable version — same content, for the person on the other end
However you get routed here, every engagement is AI-assisted but personally reviewed and delivered by me, live — no bot stands in.

Everything I publish is in service of one bet: that the next decade of engineering leadership belongs to the people who can compose agentic systems, not just consume AI tools. If that's the bet you want to make in your org, let's talk.
