cto @ enigma software systems · behavior scientist who ships
// the short version
I build AI products, full-stack web platforms, and SwiftUI apps. PhD in psychology, BCBA-D, and a decade of training in how humans actually behave — not how product managers wish they did.

// the longer one is below ↓
Most "AI workspace" demos look impressive and fall apart in production. I'm interested in the boring engineering that makes the magic actually work: tenant isolation, audit trails, human-in-the-loop approvals, the unglamorous stuff that earns trust.

I came to software the long way. Seven years training as a behavior analyst before I shipped a single line of production code. I now do both — and I've come to think the most interesting software is the kind that respects how people actually work, not how they're supposed to.

That perspective shapes everything I build. AI workflows with human review. Dashboards that surface the next decision. Compliance tools designed around the moments people are most likely to skip a step. Mobile apps that respect attention rather than capture it.

As CTO of Enigma Software Systems, I lead product and engineering for AI tools that have to hold up to real audit, real scale, and real humans. Vault AI is the flagship — but the thinking shows up everywhere I touch.

Outside of Enigma I ship a lot. iOS apps, BCBA compliance tools, CRMs, dashboards. The throughline isn't a stack — it's that every project is a small experiment in making software that's used, not just installed.

shipping

Vault AI — active work on multi-model workspaces, knowledge bases, audit verification, and the realtime gateway.

building

  • arden-ai + haven-local — privacy-first desktop AI assistants
  • NexusFlow + Tillie — SwiftUI utilities and focus workflows
  • Vault launch systems and internal tooling for Enigma

thinking about

  • progressive trust models for agentic workflows
  • graceful failure UX when an LLM is wrong but confident
  • why most "agents" feel like demos and not products

open to

strategic partnerships, selective consulting, and conversations with people building serious AI tools.

A working list of what I've shipped. Featured first, then a current GitHub inventory — full-stack AI products, compliance SaaS, native apps, dashboards, marketing sites, client work, and learning repos. Status: shipping · live · building · paused · archived.
