Product & frontend
I build web interfaces from what the product actually needs. Design, requirements and code move together: the frontend isn't a separate layer you paint on at the end.

Software
engineer
I build software with the whole system in mind: where the requirements come from, how it gets tested, and who keeps it running once I'm not around.

$ cat about.md
Who's behind the code
I started out making websites because it was the most direct way I had to build things and watch them work. Over time I moved on to more complex projects, where understanding properly what you're building ends up mattering as much as making it work.
I currently work as a software engineer on naval projects, and it's a stage where I'm learning a lot about how software is built and maintained in demanding environments.
I like understanding the systems I work with properly. How the different parts relate to each other, what sits behind each decision, and what impact a change might have further down the line. In the end the code is only one part of it: there are also the requirements, the tests, the infrastructure and everything else that makes the system actually work.
I also try to keep learning and testing new things, but always for a reason. Rather than knowing lots of technologies, I'd rather understand the ones I use properly and know when it makes sense to apply them in a project.

What I can do
I work across different parts of the software, and what interests me is understanding how it all fits: not just making it work today, but making sure it still makes sense when the time comes to maintain it.
[02]
Backend & data
I connect applications and services to their data, with APIs and databases in between. I'd rather have a boring, clear contract between components than a clever one nobody understands six months later.
[03]
Delivery & automation
I use Git, CI/CD, Docker and whatever else it takes so that building, testing and deploying comes out the same way every time. Shipping shouldn't be scary.
[04]
Systems & networking
I've got a grounding in Linux, virtualisation and networking. Knowing what happens underneath helps when the fault isn't in the code, which happens more often than you'd think.
Beyond the code
I try to be there for the whole process: working out what's needed, building it, testing it and seeing how it behaves once it's in use.

What I've developed
Projects I've taken end to end: working out what the client needs, building it, launching it and sticking around when things have to change.
◆ Academic
WASA Web
Academic project · an Instagram-style social network
An Instagram-like social network I both designed and built. Go on the backend, and a frontend laid out by hand with CSS.
It stayed on my machine: it never went to production.

Commit history
Software Engineer @ Ghenova Digital
- I build software in C++ with Qt for military ships of the Spanish Armed Forces.
- Working on Navantia's national programmes, in the combat systems area.
- I maintain and evolve mission-critical software, where a failure isn't just another ticket.
- I manage requirements and tasks in IBM's Jazz platform.
- My Spanish Personal Security Clearance (HPS) is in progress; it's needed to work with classified Defence information.
Co-founder · Software Engineer @ Atlansec
- I built modern web solutions, mostly frontend, and had a say in where the product was going.
- Para Procuradores: the platform was on a badly outdated version of PHP and Laravel, with plenty of bugs. We upgraded it and I kept fixing things until it was stable in production.
- New platform for procuradores and lawyers: we moved it to TypeScript, with Next.js and React up front and an Express API with Drizzle ORM over MySQL, plus NextAuth for authentication.
- We set up a Turborepo + pnpm monorepo: a portal for procuradores, another for lawyers, an admin panel, the API and a React Native mobile app, with tests in Vitest and Playwright.
- I gathered requirements with the client and organised the work and the issues in YouTrack.
- GIEQs: a web platform for the medical and education sector.
Erasmus @ Sapienza · Università di Roma
- A whole academic year in Rome, studying at another university and in another language.
- I came back with a B1 in Italian.
- Several course projects that sparked my urge to dig deeper into computing.
