Maria Zuheros

Scalable web applications, and the reliable systems that sit behind them.

I build across JavaScript, TypeScript and React on the front, with Python and cloud infrastructure behind — favouring systems that stay legible as they grow.

Currently specialising in AI and Web3, and building open-source tooling for browser-based agents.

Profile

Engineer, builder

I'm a software engineer based in the United Kingdom, focused on building scalable web applications and reliable backend systems — working across JavaScript, TypeScript, React, Python and the cloud.

Originally from Madrid, Spain, I sharpen my craft through personal and collaborative projects, and I'm actively specialising in AI and Web3 — the areas where the tooling is still being written.

My route into engineering ran through operations: years spent close to engineering and R&D teams, translating between people who build and people who plan. It left me with a bias for clear documentation, and for shipping the thing rather than describing it.

One thing done properly beats ten left half-built.

Selected Work

Open source

peerd

A browser that becomes an agent workstation.

An open-source browser extension that spins up local sandboxes, runs Linux VMs in WebAssembly, and connects agents peer-to-peer over WebRTC. Fully client-side and bring-your-own-key, so nothing about a session has to leave the machine it runs on.
