I build apps.
Mine, and
other people's.
I'm a Computer Engineering + Business student in Vitoria-Gasteiz, Spain. Three projects of my own, plus a commission from a land consultancy: their website and admin panel are live, and the project is still running. Everything carries the same mark: by kiacos. And yes, I take on company work.
GAUR you look at.
Nexo you use.
Planner, timetable and grade simulator for the University of the Basque Country, with eGela right there. Import your GAUR data once and that's it: free, no account, no ads.

The jar says who bottled it
Single-origin honey in one-kilo jars, one bloom per jar, plus pollen. The shop doesn't produce it: it selects it. Every sheet carries the name of the beekeeper who bottled that jar and their food-safety registration, and the family apiary is one more supplier in the catalogue.

- 1 kg, pollen sold apart
- Whoever bottled it, by name

Asegest & Forbe:
the website of a land consultancy
Urban, industrial and rural land, income-producing buildings and hotels. Their public website and the Central de Gestión they publish from without touching code are both deployed, and the project is still running: we keep extending site and panel, and I'm building the Android app for the sales team.
If your company
needs something like this,
I build it.
Outside class I take on company work. The website, the panel and the app for Asegest & Forbe came from exactly that: one commission, a fixed quote, and something that's live and used every day. The same can be done with yours, and in less time than you'll be quoted elsewhere.
At least 96 out of 100 across the board
Every website I build scores at least 96 in all four Google PageSpeed Insights categories: performance, accessibility, best practices and SEO. On mobile and on desktop.
One physical HTML file per page, generated at build time, with its own SEO and sitemap. Fast on mobile and not tied to anyone's template.
A back office built for you: publish, hide, measure and write without touching code or waiting for someone to deploy.
One codebase for Android and iOS with Kotlin Multiplatform. It's what's behind Nexo and the Asegest & Forbe app.
How I work
Two lines is enough: what you do, what's broken and by when. I always reply, even if it's to say I don't have the hours.

What used to take
a team and a year
takes me months.
Since April 2026 I've built with AI — Claude Code — folded into how I work: I set the architecture, the design, the judgement and what gets in; it eats the mechanical part. 5 months of taking the experiment seriously, and this is what came out.
Data model, screens, priorities and what stays out: that isn't delegated. The AI writes and refactors at my pace, not its own.
I review the code that stays. That's why I can maintain it, fix it when it breaks and explain it to whoever asks.
What a company quotes as months of several people fits here into weeks of one. That margin is what whoever hires me gains.
“All of this is a demonstration: with the right knowledge, you can build very big things today without a big team behind you. That's my goal.”
Where you can see it
I say it because it's part of the result, not because it sounds modern. The journal has the detail of how each thing was built.
I've spent years
training. This
moment won't repeat.
Two years of a vocational diploma in Microcomputer Systems and Networks (2022–24) and two of a higher diploma in Web Application Development (2024–26), the last one on an intensive dual track: a full year inside Abas Forterro on a scholarship, working and studying at the same time. Now, the double degree in Computer Engineering + Business. I'm not a company, but I work like one: what I hand over gets maintained. And I'm not waiting for one more degree before I build — with AI, what used to take years takes months, and that moment is now.
