Live · buildingA home for web games you actually play with friends — party games rebuilt to feel fast, expressive, and alive right in the browser.
Three titles live so far — Cards Against Humanity, Blank Slate, and Wavelength — each rebuilt for real-time play on a call or in a group chat, with no installs or accounts to fight through. More titles in the pipeline.

Case studyAn autonomous brand-asset CDN built for modern product and engineering teams.
Connects directly to Figma, auto-compiles and optimizes assets, then serves them globally through permanent edge URLs — no pull requests, rebuilds or redeploys. An MCP layer lets agents search, analyze and propose asset changes with approval and rollback built in.

in this order,
every time.
01
Frame the smallest thing worth shipping
Most projects die of scope, not of bad taste. I cut until one flow is left standing, then design that flow until it feels obvious.
Journey mapsIAOne-flow scope
02
Prototype in code, not in slides
Figma is where I think; the browser is where I decide. Real type, real latency, real states — the compromises show up while they're still cheap.

Ship it, watch it, cut it back
Launch is the start of the research. I instrument what shipped, read where people hesitate, and remove whatever the numbers can't justify.

/ 07 — AboutThe long story, short
About
I'm a UX engineer who refuses to pick a side. Most days that means Google Meet at scale; most nights it means a product of my own with nobody else to hand the hard part to.
Nine years, six teams, two of them at Google. A stint at Cars24 where I lifted UI performance by 60%. The through-line is the same everywhere: the interface is the product, and someone has to own it end to end.
Off-screen I write poetry, perform theatre, and once played national-level cricket. The poet taught me to listen. The theatre kid taught me timing. Both show up in the work.
