Product + Engineering for AI

I build and ship AI products end to end.

I work across product and engineering: define scope, design the interaction model, implement integrations, launch, and measure what changes user behavior.

See Work Book Intro Call

Focus

Where I Am Most Useful

Best fit: teams that need both product management and execution power, especially when priorities are still ambiguous.

Startup to enterprise teams
User-facing AI workflows
Unscoped discovery to scoped execution
PM + engineering bridge
Activation and retention metrics

I can step in before scope exists: clarify user and business goals, define the right slice, then own 0->1 delivery through launch and follow-up decisions.

Delivery

What You Get

My default operating loop: define clear scope, ship, measure usage, and iterate.

Shipped Product

A feature users can touch, not just docs.
Product Clarity

Flows, specs, and decisions unblocked.
Safe AI UX

Constraints, failure modes, and guardrails in place.
Iteration Loop

Events and user feedback wired for fast learning.

Art Projects

Technology, Humanity, and Meaning

I also build art-led software exploring AI, consciousness, spirituality, and human behavior. Bonzen sits on the practical behavioral-tech side of that same exploration.

Circuit Pet, Horse Flock Simulator, and Divine Machine are explicit art/critique pieces. Bonzen applies similar questions to behavior design: how interfaces can guide attention, reflection, and better daily decisions.

About

Short Snapshot

I work at the product/engineering boundary and can own delivery from idea to production.

How I Help

Define the journey, ship the feature, and set up the iteration loop tied to product hypotheses.

Background

Previously: Unyte, SmartHalo, Esper, IBM. Current focus: Bonzen and practical AI products people return to.

Engagement

Unscoped product discovery, scoped builds, and part-time support with clear written PM + engineering updates.
