Michael Kaminski — I build AI agents that run in production

Agent infrastructure, MCP servers, and eval harnesses inside a regulated lender. Python and TypeScript. Atlanta, relocating to New York City.

What I'm looking for: senior product roles at the agent layer — Technical Product Manager, Senior Product Owner, or PM for an agent platform — at teams shipping AI agents into production, especially where the environment is regulated and the evidence trail matters. Open to fractional and full-time.

I'm a technical product manager working at the agent layer. I took an AI agent capability from prototype through security, legal, and compliance review to production inside a regulated lender, and I build custom Model Context Protocol (MCP) servers, multi-agent pipelines, and eval harnesses in Python and TypeScript. What is unusual about the combination is that I can price a system and I can ship it: before the agent work I spent years in corporate finance and strategy, and I have authored Terraform modules with multi-environment remote state and operated production Kubernetes clusters.

Latest: Nvidia + Hugging Face: $12.9B to Close the Gap Between a Model Card and a Running Kernel — Nvidia reportedly agreed to buy Hugging Face for $12.9 billion — nine months after Hugging Face turned down a $500M investment at a $7B valuation, an 84% step-up. I am long NVDA and Hugging Face is where my weights come from, so read the bull case accordingly. The honest arithmetic: my break-even for self-hosting is 3.04 billion tokens a month and I am nowhere near it. The line item this deal actually attacks is not the GPU-hour. It is the week of engineering between a download and a running kernel.

About

I build AI agents that run in production. Most of what that involves is not the model — it is the tool surface the model is allowed to call, the evidence the system has to produce afterwards, and the gates that stop it doing anything it cannot undo.

I came to it sideways. I spent years in corporate finance and strategy — capital markets, divestitures, an IPO, a $4B share repurchase — and the through-line is the same in both halves of that career: the number has to reconcile, and somebody has to be able to check it eighteen months later. That instinct turns out to be exactly what an agent needs before it can go anywhere near a regulated decision.

So I can price a system and I can ship it. I have authored Terraform modules with multi-environment remote state and run production Kubernetes; I have also built the financial model a private-equity board expected. Very few people building agent infrastructure can also make the business case for it, and that combination is the whole of what I am useful for.

I write about the parts that went wrong, because those are the parts worth reading. The statistical gate I built for my own agent's instruction file turned out to be decorative once I ran the power calculation on it. A pipeline I looked at daily was quietly rewriting its own history until I added one more file. Both are on this site with the arithmetic shown.

• Nvidia + Hugging Face: $12.9B to Close the Gap Between a Model Card and a Running Kernel — Nvidia reportedly agreed to buy Hugging Face for $12.9 billion — nine months after Hugging Face turned down a $500M investment at a $7B valuation, an 84% step-up. I am long NVDA and Hugging Face is where my weights come from, so read the bull case accordingly. The honest arithmetic: my break-even for self-hosting is 3.04 billion tokens a month and I am nowhere near it. The line item this deal actually attacks is not the GPU-hour. It is the week of engineering between a download and a running kernel.
• One Knowledge Base, Four Surfaces: Pages, Graph, Search Index, and MCP — The Genome of Games publishes 1,180 records four ways — 1,245 static pages, an interactive graph, a 126 KB search index, and an 8-tool MCP server. One build writes all four in 0.39 seconds. The MCP server never queries the site; it imports a build artifact, so an agent and a crawler cannot disagree. The one surface the build does not own has already drifted by 7,492 links.
• Shipping an AI Agent Through Compliance Review in Regulated Lending — On May 12, 2025 the CFPB withdrew 67 guidance documents in a single notice, including both circulars covering adverse-action notices for complex algorithms. The underlying duty did not move. Build the agent against the statute and against the evidence it will have to produce — starting with a 120-day retention floor that most agent logs miss.
• Statistical Gating for Agent Instruction Changes — Every edit to an agent's instruction file is an experiment. Mine requires a statistically significant improvement — Welch's t-test, p < 0.10, at least a 5% lift — against a 14-day rolling baseline before the change is allowed to stay. Then the power calculation showed the 14-day window can only detect a 0.97 standard-deviation shift, which makes the 5% threshold decorative.
• I Gave My Website a Voice, and the Voice Was the Easy Part — There is now a digital twin on my homepage you can talk to out loud, hands-free, in a clone of my voice. Getting it to sound like me took an afternoon. Getting it to sound like a person took rewriting how it writes.
• I Shipped the Same Pull Request Twice and Only Noticed the Second Time — Behind the Build, Vol. 8: two new tabs — Websites and Products — landed a day apart and turned out to be the exact same diff wearing different screenshots. What that repetition taught me about when a pattern is worth abstracting (and when it very much is not).
• Every URL on My Site Returns 200, Including the Ones That Don't Exist — Behind the Build, Vol. 7: I had to prove four recovered articles were actually live, and discovered my own verification was a test that could never fail. The fix came from a filename.
• My Automations Didn't Crash. They Just Stopped Talking. — Behind the Build, Vol. 6: the daily-article robot quietly skipped four days without erroring once. A look at the fleet of small agents I now run across a portfolio site, a trading account, a resale business, and a spend audit — and why silence is the failure mode nobody instruments for.
• My Portfolio's Robot Diarist Cloned Itself Three Times, and They All Wrote About the Same Week — Behind the Build, Vol. 5: I sat down to write today's "what I shipped" entry and found three separate unmerged pull requests already fighting over the same volume number. A classic race condition, just wearing a writer's hat.
• I Built Analytics to Watch My Site, and Discovered It Was Watching Nothing — Behind the Build, Vol. 4: wiring up real product analytics turned up a silent reverse proxy eating every POST request, a dropped entry pageview, and a Gantt chart bug where two bars collided despite their dates never touching.
• I Got Locked Out of My Own GitHub Account (Sort Of), So I Found the Back Door — Behind the Build, Vol. 3: adding a Products tab for my desktop tools meant fetching screenshots from repos my own session wasn't allowed to touch — and learning the honest way to handle a missing screenshot instead of faking one.
• I Built a Blog That Yells at Me If Two Robots Write the Same Diary Entry — Behind the Build, Vol. 2: today's work was a new Websites tab showcasing live production sites, plus a small guardrail that stops this very writing series from ever double-booking a day.
• Why Fintech Belongs in Atlanta — and Why That Matters for Your Cap Table — Atlanta quietly processes a huge share of the world's card transactions and has produced a run of fintech exits. Here's what that ecosystem means for founders building here — and the finance-plus-engineering talent it creates.
• I Spent a Day Teaching Robots How to Read My Résumé (So You Don't Have To) — Behind the Build, Vol. 1: a lighthearted look at the SEO/AEO overhaul of this very site — JSON-LD schema soup, an llms.txt for AI crawlers, and the great WebP-ification of my own face.
• Fractional CFO vs. Fractional CTO: Which Does Your Early Fintech Need First? — A practical guide for fintech founders deciding between fractional CFO and CTO help — the signals that tell you which seat is actually on fire, and how to sequence the two.
• Quality of Earnings, Explained for Fintech Founders — What a Quality of Earnings (QoE) analysis actually looks at, why fintech QoE is different, and how founders can be ready before a buyer or lender runs one.
• Why Your Fintech's CFO Should Be Able to Read the Codebase — In fintech the ledger is the product. A finance leader who can read the code that produces the numbers removes the most expensive translation layer in the company.

Beyond his technical expertise, Michael is a great collaborator who brings a positive attitude and problem-solving mindset to every project. He's always appreciative of others and a fantastic team player. Any organization would be lucky to have him!

I worked very closely with Michael during his time as CFO for Superior Contracting & Maintenance and would not hesitate to recommend him for Senior and Executive leadership roles. Michael's superpower is a double whammy of emotional intelligence and strategic vision. A true servant leader that endeavors to learn and understand his team and employees and their motivators/drivers as part of the business, Michael places a premium on a positive culture to drive results from a happy, encouraged, and supported team. With a strategic vision and passion for technology, Michael brings a unique touch to his roles, often finding new tech and applications to streamline operational workflows before most people even become aware of the platform(s). Michael is a perennial educator and facilitator. Over the years, I have watched Michael teach corporate financing and business to dozens of coworkers (myself included) simply because they asked and he truly believes education, personal/professional development, and understanding the "why" build great leaders and greater companies. Michael is a first round draft pick and will be an outstanding impact player and leader for any company lucky enough to have him.

In my professional career, I have never come across someone as willing & able to use their knowledge and technical skill set to advance the company as a whole as Michael. In our time together at Momnt, he consistently went above and beyond to help others solve complex problems. When coworkers would post questions on our internal messaging system, Michael was usually the first to reach out with answers. And if he didn't know at the time, he would research the issue and come back with solutions - all while outperforming in his own job duties. What most impressed me about Michael was his drive. It became clear early on that he was not motivated by public accolades or promotions - he simply wanted to do the best job possible at any task in front of him for the benefit of the company. Any business looking for someone highly skilled in coding (SQL, Python,etc.), statistics, data analysis, financial modeling, strategy, and countless other hard & soft skills would greatly benefit from having Michael on staff.

I had the privilege of working closely with Michael Kaminski during their time as CFO at Superior Contracting & Maintenance, and I can confidently say that they are one of the most talented and versatile leaders I've had the pleasure of working with.

Whether it was overseeing large-scale system upgrades or aligning financial and technological strategies, Michael shows a remarkable aptitude for organization and leadership in any capacity. Michael has a unique talent of meshing a 'Big Picture' mindset while maintaining a true genuine, compassionate approach to management. I have no doubt that Michael would excel in any senior leadership role.

I had the pleasure of working alongside Kaminski, and I can confidently say he is one of the most intelligent and results-driven professionals I've encountered. His ability to engineer high-performance data solutions and drive efficiency at scale is truly impressive. His leadership in managing a development team while directly supporting executive leadership showcased his ability to balance both strategic and technical initiatives seamlessly. His efforts directly lead to tens of millions in capital being generated or saved that otherwise would have never come to fruition. One of his standout achievements was leading critical reporting and credit functions for Capital Markets transactions, facilitating deals exceeding $300M in unsecured loans. His expertise in Python, SQL, AWS, and data engineering was instrumental in enhancing risk, compliance, and operational workflows. Beyond his technical expertise, Kaminski is a problem solver who thrives in high-stakes environments.
