## Projects

- [Khada](https://modelviewer.lol): An interactive 3D platform for League of Legends, available on the web, iOS and Android. It renders characters, skins and animations directly in the browser with Three.js and WebGL/WebGPU, with augmented reality on mobile. I built the product and its automated asset pipeline end to end, from processing game data and 3D models to global delivery through Cloudflare Workers and R2.
- [Speedra](https://apps.apple.com/app/speedra-gps-speedometer-hud/id6757438450): A native iOS GPS speedometer with a windshield HUD mode, Live Activities and Dynamic Island, and Lock Screen widgets. Built in SwiftUI on CoreLocation, with paid upgrades through StoreKit. Live on the App Store.
- [Selfieport](https://selfie-anywhere.app): A live AI photo app that drops you into any location on Earth from a single selfie. I built and run the full system solo: a REST API on Cloudflare Workers (Hono) backed by a D1 SQL database with Drizzle migrations, user authentication, asynchronous image generation through Cloudflare Queues, R2 storage, and Google Gemini for the AI, plus paid subscriptions and CI/CD. Native app available on the App Store.
- [gltf2usdz.online](https://gltf2usdz.online): An open-source tool that converts 3D models from .GLTF to .USDZ (the AR format for Apple devices) entirely in the browser. The conversion runs client-side in a Web Worker via WebAssembly, so files never leave the device. Ships as a static Cloudflare Worker.
- [ionic-level](https://ionic-level.pages.dev): An open-source, browser-based clone of the iOS Level app. It reads the device accelerometer via the Motion Web API to measure surface inclination, no install required.
