Selected history

A few milestones behind how I work and what I build today.

2022-2025

Unity asset development

Unity programmer and tool builder

Before the current AI-heavy phase, I spent years building Unity assets and frameworks that reached a large audience of developers.

  • Created 5-star Unity assets, including tools for procedural level design and physics-reactive VR NPCs.
  • Learned how to package advanced systems so they are understandable, documented, and genuinely useful.
  • Turned the Asset Store from a learning platform into a profitable technical business with strong user feedback.

2025-2026

Roam AI text-to-game startup

Core gameplay and AI systems contractor

I joined Roam as a core contractor on a small team building a text-to-game experience at the level where gameplay engineering and AI systems start overlapping.

  • Built player mechanics, enemy AI, networking, physics interactions, and world-building systems with the team.
  • Selected for two company-supported San Francisco stays, spending four months there for direct in-person collaboration with the core team.
  • Worked closely with teammates across gameplay development, internal tooling, product context, and urgent AI-driven problem solving.

2026-now

Independent AI products

Product builder and AI systems designer

My current work is centered on personal products where AI systems, product thinking, and behavior design meet.

  • Launched Voice of Self, a voice-first reflection app for noticing recurring worries, resolved worries, and personal growth.
  • Building PlanKept, a local-first plan-enforcement app that turns written goals into reminders, app limits, and proof review.
  • Using agentic workflows as part of the way I build, research, and iterate on software.
