nauran ES

Full-stack developer

I build websites, mobile apps and the infrastructure that holds them up.

I'm Arnau. I sign as nauran. I design and build products end to end: from the API contract to the phone screen, and from the container to the backup.

01

What I do

Websites and web apps

Sites and applications with Next.js or SvelteKit and TypeScript. Headless CMS so clients edit their own content, internationalisation, and forms that land where they should.

Mobile apps

Native clients with React Native and Expo for iOS and Android, built to work offline and to share the data contract with the server.

Infrastructure and deployment

Docker, Cloudflare, CI/CD, backups and monitoring. Services deployed with care, easy to operate and to recover.

Automation and AI agents

Workflows built on language models: extracting data from images, bots, and coding-agent sessions coordinated under clear rules.

Projects

What I have going on: client work and products of my own that I am getting ready for a public release.

How I work

  1. Spec first

    Every non-trivial change starts with a short document: what, why and how it is verified. Architecture decisions are written down as ADRs.

  2. Green gate

    Nothing gets integrated without typecheck, lint, tests and build passing on the actual commit. Linear history, one task per branch.

  3. Secure by default

    No secret in a commit or on the command line. One identity per machine, keys in hardware, and an audit trail of what goes in and out.

  4. Documentation people read

    Every repo states where it stands and what is missing, so anyone, human or agent, can pick up where it was left.
