Developer & UX/UI Designer ✺ AI‑native
Selected work
2019 → 2026
I'm a developer and designer obsessed with everything digital — building products where engineering rigor meets playful, considered design. From apps used by thousands daily to AI on Google Glass, I create things people genuinely enjoy using.
Two stories where product thinking, engineering and visual craft meet — followed by the full project index.
CAI is a CLI health check for AI-coding repositories — exposing bloated context, instruction drift and hidden token cost before they slow the team down.
A companion for Kickbase managers with more than 1,000 daily users — reliable when lineups drop, fast when every second counts.
A handful of smaller, older or experimental projects that didn't make the main list — still live, still linked, just not the headline work.
Products built around language models — tool use, agentic flows, structured output. OpenAI & Claude APIs in production, not in slides.
Shipped GPT-4 Vision on Google Glass before it was cool — a working assistant on discontinued hardware. Voice, image, text: one interface.
The entire toolchain is AI-assisted — prototyping, code review, design iteration. Ideas ship in days, not quarters. This site included.
Have an idea worth building?
