Why most AI projects fail

Not because the model is wrong. Because AI gets bolted onto software instead of designed as part of it. The model is the easy part. Everything around it — architecture, context, how it lands with the user — is where the system wins or loses.

That's where UX and engineering meet. That's where I work.

Three ways to work together

Custom AI-native software

I design and build the full system with embedded AI from the architecture itself. Scoped project, delivered end-to-end.

AI layer on existing software

If you already have your own platform, I add AI inside the product, not as a separate module. Designed to integrate with your existing UX and architecture.

AI Consulting

Diagnosis, architecture, audit of features that don't land. To define what to build, what to fix, or what to scrap before writing a single line of code.

UX, architecture, and AI in the same project. That combination is what separates AI that ships from AI that gets used.
