Softplan

Full-stack engineer on case-management software for the Court of Justice of São Paulo, Latin America's largest court, handling around a quarter of all cases in Brazil's judiciary.

Worked across two systems: one handling the court's administrative operations (procurement, payroll, court-ordered payments) across all of São Paulo's judicial districts, and another serving the state's network of notary and registry offices.
Built Java and Spring Boot REST services over PostgreSQL, secured with OAuth2/JWT/TLS.
Containerized services with Docker and shipped them through CI/CD on AWS.
Built and maintained a proprietary, WCAG-accessible design system used across the platform.

Khada

A web and mobile app (iOS and Android) that renders every 3D model from League of Legends at any angle, with animations and AR. It serves 5M+ page views a month on cloud-native infra: Cloudflare Workers at the edge, R2 for assets, Pages for delivery. I built and run it end to end, monetized with ads.

Selfie Anywhere

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

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

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.
