Staff Frontend Engineer · Design Systems · Real-Time Communications · Agentic Tooling
I build frontend platforms that other engineers build on top of — design systems, shared infrastructure packages, and cross-platform apps with React, React Native, Electron and TypeScript.
- Design systems at scale — semantic token layers, multi-brand theming, per-component versioning
- Agentic engineering — harness design, multi-agent pipelines, and where LLMs actually earn their keep in a dev workflow
- Real-time comms on the web — WebRTC, SIP, call quality, latency and jitter
- The edges of the browser — WASM, WebGPU
- Off-screen: dry gardens and permaculture in northern Portugal, running, and a guitar
- Based in Caminha, Portugal — remote-first, always
- I write about frontend architecture at ruijadom.com
