Part-time, about 16 hours a week, writing Go. For the Deventer municipality I own everything from design and UX to architecture and build.
I’m also designing, from zero, how working alongside an AI agent should feel.

Microsoft Quantum. Built retrieval for an AI-native lab notebook, so quantum researchers get cited answers from their own data. Case study Microsoft Quantum

Researchers’ measurements and reports lived apart. I linked them in a knowledge graph and gave the agents in their VS Code four tools to search it.
The rule I designed around: no evidence, no answer. Every answer cites the report it came from.
I demoed it twice to the whole Quantum Delft office, including leadership.
- BusinessSoon
Launching Depor360. A mobile-first platform for sports events in rural Spain: registrations, QR bibs, payments, and tools for organisers, sponsors and volunteers. Co-founded with my father. I designed and built everything technical; he runs finance and grants. depor360.com
A chance to build a company from zero with my father, backed by an EU grant.

Fully financed by a mid-five-figure EU grant (NextGenerationEU, through GVANEXT from the Generalitat Valenciana). The App Store and Google Play releases are on their way.
Built with React, TypeScript and Vite on the front end; Hono on Bun, Prisma and PostgreSQL with PostGIS on the back end; Stripe Connect for payments; deployed on Fly.io and Netlify. The marketing site runs on Astro and Cloudflare Pages.

Crowe Peak (now OneLane). Our team of five built an AI Outlook add-in that files tax advisors’ emails for them. Case study OneLane

Our TU Delft Software Project. We all worked across the whole system; the part I built on my own was the model-agnostic classification layer, which routes each email to one of about 2,800 SharePoint destinations.
Three audiences had to be happy: Crowe Peak needed it to fit real consulting work, TU Delft needed academic rigour, and the advisors just needed it not to slow them down.

We split the work between us as a team and kept each other moving under the time pressure.
My part: processing and cleaning a large dataset in Java, and designing the algorithm behind a machine learning model that suggests the best decisions for drivers based on that data.
- LeadershipNow
Head of Technology. I run the tech behind a 500+ member NGO, and I’m building the platform it will run on after I leave. EYP story EYP España
Volunteers change every year, so whatever I build has to keep working when I am not there to explain it.

What I own: our Oracle Cloud setup and n8n automations; a self-hosted platform with our internal tools (ERP, CRM and volunteer tooling) used by 70 people; the website, accounts, member management and permissions; and our AI policy and direction.
The biggest piece right now is the platform: making it maintainable and able to grow, with proper cloud and secret management.
The goal is to leave the organisation in a good place: clean and organised, with rules set and direction decided, so someone less technical or less experienced can take it over without it crumbling.
- Leadership
Head organiser. Led a team of 7 to run the Valencia regional session for 100 delegates, owning everything from budget and sponsors to venue and programme.
Owning the outcome means owning it even when the mistake wasn’t yours.

The hardest moment was finding a replacement venue for the General Assembly.
The bigger lesson was ownership. When something a team member was responsible for went wrong, it was still my outcome, and mine to fix.
The way up: logistics and operations for the Valencia and Mallorca regional sessions (Feb 2024), then logistics for the national conference in Valencia (Sep 2024). After this, corporate sponsorships for the Euro-Mediterranean Youth Summit in Málaga (Oct 2025): 300 people from 40+ countries.

Moving to Delft. Moved to the Netherlands for a BSc in Computer Science & Engineering at TU Delft.
I wanted the most demanding place I could get into. In Europe, that was Delft.

Why CS: my computer science teacher in high school made me love it. It is about solving problems, it blends many disciplines, and it applies everywhere.
Why business on top: I think even software engineers need to understand how their company creates value, innovates and makes money.
- Education
Graduation. 9.91 in the Spanish Bachillerato and A*AAB at A-Level, recognised with the top grades of my year. As head student, I gave the graduation speech.
- Competition
Young Business Talents finalist. Led a team of four friends in Spain’s national business simulation, where students run a virtual company. We came first in the Valencian Community, then competed in the national final in Madrid.

It was my third year competing, and the first time we made the final.
The final brought together 343 students from 84 schools across Spain.

Before that: deputy head boy in primary, and class representative in 7 of the previous 9 years.
I pushed for events that brought the whole school community together, like art galleries, fairs and cross-year events. I also set up digital inboxes for mental health and suggestions, which never really took off.
At the end of the year, I gave the speech at our graduation.
- Debate
First EYP session. Delegate in the Human Rights committee (DROI) at the Valencia regional session, working on sex trafficking from Ukraine and Moldova into European countries.
MUN got me through the door. I stayed because EYP is about the people, consensus and growing together, not winning the debate.

- Work
Two summers in Austria. My first real job, at 16: part-time on the international VAT return team at Diesel 24 in Klagenfurt, filing paperwork and sometimes tax returns, over the summers of 2022 and 2023.
- Business
Tutoring my year. Ran paid IGCSE tutoring in Maths, Physics and more for classmates in my year, while sitting the same exams myself.

- Debate
Model United Nations. Five years of MUN conferences, mainly in Valencia, Madrid and Nice. I loved the debating as much as the politics, learning about other countries, and the people.
It’s what made me try EYP.

- Business
The Dipper market. Sold 800+ Dippers in a week at break, and added paid subscriptions when we kept selling out.
My first lesson in product: we made the demand, someone else captured it.
Read moreShow less
It lasted a few weeks. We bought boxes of Dippers from local shops and sold them in the playground at break.
We ran out every day, so we sold subscriptions for priority buying. We had also created demand we couldn’t meet: someone else started reselling Dippers at second break, at a premium, to everyone we had sold out on.
I kept the books by hand in a notebook: how many we expected to sell the next day, who bought the most and when, who to target, how to price the subscriptions, and how much we were actually making.
Then the school shut us down.
