An AI stylist that dresses you from the clothes you already own

After four years aligning 80+ teams on Alexa's AI platform, I wanted to prove I could take an AI product from a blank repo to real users with my own hands. Brummell is the result: a consumer app, a merchant app and an agent-ready API, all running on one shared data layer.

I own all of it: strategy, product specs, architecture, code, AI evals, pricing, legal and go-to-market. Claude Code agents are my engineering team. I run them the way I ran teams at Amazon, with written specs, definitions of done and quality gates.

Beyond code

Everything else

Everything a real product needs: a 63-tile metrics dashboard where every feature ships with its own kill gate, the website, versioned Privacy Policy and Terms, biometric-safe vision prompts (clothing only, never faces), a vendor register, a security audit, App Store and Shopify compliance, pricing and outbound GTM.

How I run a one-person product org

Strategy before code

Every feature starts as a written spec and decision record. Before the beta, I set phase gates and kill conditions, such as stopping and redesigning the matcher if fewer than 60% of Day-1 users would wear a suggestion. The data decides what gets built next, not my enthusiasm.

AI agents as the engineering team

I assign each task to a model and effort level, with an explicit definition of done. I learned the hard way that agents will fake completion and game a grep-based "done" check. Now "done" means the verification actually ran and passed.

Quality as a system

Golden-set evals gate every prompt or model change. A weekly latency regression job runs in CI. Row-level security covers every table. Performance budgets are enforced down to the byte.

Early results: measured, not claimed

All four products are in early beta with limited public visibility, so user numbers are too early to mean anything yet. These are the results I can measure honestly.

Decisions & learnings
Don't trust your own judgeMy LLM-as-judge agreed with a professional stylist's ratings at chance level (κ = 0.02). I stopped paying for it and anchored quality on expert labels and real users instead. An eval is a product with its own accuracy problem.
Only sell what's provenWardrobe context cut "already owns this" shopping picks from 48% to 29%, but it didn't prove the picks were "better." So the merchant pitch became duplicate avoidance, and any revenue claim waits for a real A/B test.
The cheaper model can be the better productMoving vision and Outfit Check to a smaller model cut cost 5–8× while quality went up. That only worked because a golden-set eval gated every swap.
Propose, don't elicitThe core 1-star story across 4,203 competitor reviews was hours of setup followed by a paywall. Brummell shows outfits before a single upload, infers what it can and lets users correct by exception.

Why this matters to your team

AI has collapsed the distance between deciding and building. I can set strategy across an 80-team platform, and I can personally take a product from a blank repo to a live beta. If you are building an AI product org that needs to ship like a startup, let's talk.

AI Builder & Growth Lead

Building a full-stack growth engine from scratch

Led the complete digital transformation of a premium e-commerce brand. Beyond re-architecting the Shopify core, I executed a full website redesign with Claude Code and content overhaul to align the UX with Arquia’s high-end positioning. By integrating autonomous AI agents, I shifted the brand from manual operations to a scalable, evidence-based growth engine.

Key decisionBuilt the AI reporting infrastructure before optimising the funnel. Without clean data there was no reliable signal. The agents gave visibility first, every growth decision after was evidence-based.
