Software engineer AI agent governance

I'm building TheFittClub solo: a production platform shipped by a fleet of AI agents I govern. The whole process, documented here.

Team

One engineer covering the whole team you'd hire — product, code, design, QA and deploy — with a governed agent fleet.

203K
Audience

Followers I built and monetized solo for TheFittClub: 114 paying customers and $30,973 in revenue — the product whose platform I'm now rebuilding.

0
QA

Agent merges without my review. A test catches whether the AI has decayed before I trust it.

The team you don't hire

The org chart you would hire to ship your product — in one engineer with governed agents.

01
Frontend A React Router v7 app, an in-house design system, and every component.
02
Backend 90 service modules and the data layer on Cloudflare Workers.
03
Design and design system Tokens, a quality rubric, and the entire visual SSOT.
04
QA 2,900+ tests across five layers, from unit to end-to-end.
05
DevOps and platform 16 CI/CD pipelines, edge deploys, and a nightly backup.
06
Product The spec system, the roadmap, and 16 recorded architecture decisions.
07
Internationalization Spanish and English at parity, not a last-minute translation.
08
Growth 203K of audience and the content that built it.
09
AI agent governance The system that lets one person cover everything above — the role your team doesn't have.

I don't sell hours of typing code — AI already does that. I sell judgment: knowing what to build, how to govern the AI that builds it, and how to prove it works. I'm not taking new projects right now; the waitlist is open.

About

I came to software from civil engineering. The instinct stayed: load paths, tolerances, things that hold.

Now I design and govern fleets of AI agents to ship production software solo — with the review discipline a team would demand. The agents move fast; the standard is mine, and it doesn't move.

Have a problem worth solving well?

I'm not taking new projects right now — I'm building TheFittClub full time. I still read everything that comes in: tell me what you're building and I'll let you know when a slot opens.
