I build creative products end-to-end

From rough ideas and rapid prototypes to reliable, production-ready systems, I build creative products with a clear bias toward execution. Most of my career has been in small, fast-moving teams, working across games, AR experiences, full-stack SaaS, data products, blockchain tooling, and shader-driven web experiments.

I do my best work when collaborating closely with designers, artists, and founders to shape both the product direction and the technical foundation.

I'm looking for

Remote, early-stage or growth-stage startups building creative, interactive, or slightly unconventional products. I'm especially drawn to games, AR, creative tools, and products where engineering, design, and experimentation overlap.

I am looking for a team that wants someone who can help shape the product and carry the engineering from prototype to production.
