Build Partner

Your AI-Built App Needs an Experienced Build Partner.

A second set of eyes from someone who ships production code and runs a product org. I review AI-built apps for non-technical founders, and run product and technical diligence for investors and operators.

Who This Is For

Founders Building With AI Tools

You shipped an MVP with Claude Code, Cursor, Bolt, Lovable, or v0. You need to know what's broken before you launch, take payments, or face an investor's technical question. Start with a Security Health Check.

Investors and VCs

You're evaluating a build before writing a check, or running diligence on a portfolio company. You need product and technical judgment that doesn't sit on one side of the line. We scope a focused engagement around the deal.

Operators and Acquirers

You're weighing build-vs-buy, evaluating an internal team's work, or considering an acquisition target. You need a sharp outside read from someone who's built and led product. We scope around the decision.

The Issues I See in Every AI-Built App

I audit AI-generated code every day for my own products and for other founders. Here's what keeps showing up.

Authentication Edge Cases

Cursor generated clean auth code but missed session timeout handling, leaving users logged in indefinitely. Classic AI oversight.

Performance Bottlenecks

AI-generated database queries were doing 47 calls per page load. Rewrote it to 3. This is what kills apps at scale.

Security Vulnerabilities

Security scans found 12 issues. 8 were low-risk noise, 4 needed immediate fixes. Knowing which is which matters.

Exposed API Keys in Client Code

Lovable-generated frontend was bundling the OpenAI API key into the JavaScript shipped to browsers. Anyone could have extracted it and run up unlimited charges.

Missing Row-Level Security

Cursor-generated CRUD endpoints had no RLS policies. Any logged-in user could read or modify any other user's data by changing an ID in the URL.

No Error Monitoring

Errors were happening on 18% of user sessions and the founder had no idea. Sentry took 20 minutes to wire up and immediately surfaced three critical bugs.

PII Leaking into Analytics

A scheduling app was logging full names and email addresses into analytics for debugging. Never used. A right-to-erasure request would have surfaced it fast.

These aren't hypothetical. They're the real issues that show up when you build with Claude Code, Codex, Cursor, Bolt, or Lovable. Let me catch them before your users do.

Why Trust me With This

I've spent 23 years on both sides of the line. 15 years writing production code for web apps and SaaS platforms. 8 years leading product, most recently as Director of Product at Skykit, shipping enterprise SaaS and hardware to real customers. I know what breaks at scale, what security issues actually matter, and the difference between "works on my laptop" and "survives 10,000 customers."

I'm also actively building. Two AI products of my own, Quin and Versie, both built with the same AI-native tooling founders are using right now. That means I audit AI-generated code every day, model token economics every day, and ship product decisions every day. I've also shipped product in regulated environments, including a HIPAA-governed healthcare platform handling PHI, so I audit with both a security and a compliance lens.

I translate technical problems into business decisions you can understand.
