Hi, I’m Arthur Machado

Software Engineer · Auckland, New Zealand

I make things that
feel good to use.

Frontend-focused software engineer with eight years of experience. I build accessible interfaces and shared frontend systems, from a design system built to WCAG standards for Latin America's largest court to my own products serving 300K+ monthly active users.

Senior Software Developer

Oct 2021 - Jun 2026

Frontend-focused senior developer building scalable interfaces and shared frontend foundations for case-management software used by Latin America's largest court, which handles around a quarter of all cases in Brazil's judiciary.

Built and maintained reusable components and directives in a proprietary design system, improving delivery across React, Vue and Angular applications throughout the platform.
Made accessibility for people with visual impairments a core requirement, delivering WCAG-accessible Web Components with Stencil.js.
Built scalable single-page applications with TypeScript, HTML, CSS and JavaScript across React, Vue and Angular.
Worked across two large systems: one for court administration, procurement, payroll and court-ordered payments, and another supporting a statewide network of notary and registry offices.
Integrated the frontend with Java and Spring Boot REST services over PostgreSQL, secured with OAuth2/JWT/TLS, and shipped through Docker-based CI/CD on AWS with Vitest, Cypress and Playwright.

5M+ page views / month

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.

Native app available on the App Store.

open source

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.
