Cover image for Most sites tell you they're
Most sites tell you they're premium. Almost none of them make you feel it. I spent the last stretch building thirteen concept sites chasing that difference, and the thing that kept proving itself is that the feeling comes from motion you control, not motion you watch. Four are real-time 3D in the browser. A crystalline brand hero turning under studio lighting, a perfume landing lit entirely by a real HDRI environment, a neural field of instanced particles for an AI product, an architectural monolith that reveals itself out of near-black. The other nine are scroll-scrubbed video, where you drag a whiskey pour or open a box or drive into a sunrise at whatever pace you want. The visitor is the animator, which is a very different thing from watching an autoplay loop. I design it, build it, and ship it myself, so there's no handoff where the feeling leaks out between the mockup and the browser. Two things I learned that I'd want someone else to know. If you light a translucent material without a real environment map, your scene renders black. Lighting is not polish you add at the end, it's a design decision you make first, before you have anything to look at. And if you want video to scrub frame for frame off scroll position with no stutter, re-encode it all keyframe. Every frame becomes a seek target. Most people fight that stutter in JavaScript when the fix lives in the encode. Who it actually serves is anyone selling on craft rather than spec. Fragrance, architecture, spirits, dev tools. The interaction buys a few more seconds of attention right where the headline and the call to action live, and those seconds are usually the whole game. All thirteen are live and interactive, and labeled as concepts because that's what they are. Still chewing on one thing. Where's the line where motion stops serving the brand and becomes the thing people remember instead of the brand? https://xkaii.studio/ui-ux-designs/

Cover image for MessyAPI is a production-ready developer
MessyAPI is a production-ready developer infrastructure platform I built to eliminate repetitive data utility work. It gives developers one API to clean, validate, match, transform, protect, and analyze messy data instead of rebuilding those capabilities for every application. I designed the platform around real production requirements, including API-key authentication, tenant isolation, usage metering, rate limiting, idempotency, asynchronous jobs, retries, webhooks, observability, and secure data handling. MessyAPI also includes JavaScript and Python SDKs, OpenAPI, MCP support, CLI tooling, RapidAPI integration, interactive testing, and composable workflows for chaining multiple data operations together. The goal was simple: turn common data infrastructure developers repeatedly build themselves into one reliable API.

Cover image for I designed and built MessyProof
I designed and built MessyProof to solve a growing problem with AI-built software: generating an application is getting easier, but understanding what was actually built — and whether it’s production-ready — is still difficult. MessyProof acts as an independent verification layer, analyzing an application’s architecture, dependencies, integrations, changes, security signals, and production readiness. It turns that analysis into a plain-English App Passport backed by evidence rather than assumptions. I led the product strategy, UX, verification model, application architecture, integrations, and go-to-market positioning from concept through implementation.
