Struct — the engineer
Flux — the creative
Software that stays on. I build back-office systems, automations and sites for real businesses, like the system that runs twenty-four stores. Open to developer roles in Valencia and remote.
For teams hiring
I've spent the last years building and running software that people depend on every working day. I write the backend, the interface and the glue to the hardware, and I stay on call when it breaks.
SvaPro runs the tills of twenty-four stores every day: fiscal receipts, card terminals, stock between stores and excise reports to the customs agency.
Laravel and React for the ERP, Next.js for sites, Expo for mobile apps, Docker and my own server with Coolify for deploys. Database design to pixel polish.
Agents built on the Anthropic SDK, MCP servers, n8n automations and voice assistants, wired into real workflows rather than demos.
Run a business and need software built? That's the other half of what I do.
See how I work →Case study
A multi-tenant retail ERP that runs the tills, stock and tax reporting of QuiSvapo, a chain of twenty-four vape shops across Italy, plus its online shop.
A vape-shop chain has needs that generic POS software doesn't cover in one place: excise duty charged per millilitre of liquid and reported to the customs agency (ADM), a fiscal printer at every till, stock moving between stores and the online shop, staff and loyalty across locations. And the tills can never stop.
One multi-tenant system: a Laravel 11 API on PostgreSQL with queues and a scheduler, a React back office and till, and small native bridges that talk to the hardware in each shop. Desktop, mobile and handheld apps are clients of the same API.
Top contributor by commits in a team of three developers: 1,954 of 5,681. I work across the data model, the API, the interface, the hardware bridges and the deploys.

The brand site and its stores
The brand site: who they are, where the stores are, who works there. It doesn't sell: it sends people to the stores, and opens the shop to those who want to buy now.

For businesses
Small businesses don't lose time because they're disorganised. They lose it because nobody ever wrote the piece of software they needed, and subscription tools are built for someone else.
The result is always the same: spreadsheets nobody updates, WhatsApp used as a back office, and one good person spending half a day copying numbers from one place to another.
That's where I come in. I look at how people really work, take the repetitive work away and give it to a machine. Then I stay: the code is mine, but the business is theirs, and it has to keep running without me.
I don't sell hours: I build things that keep working when I'm not there. The stock that checks itself, the assistant that answers at eleven at night.
How I work
Before writing a line I look at how you work now: who touches what, where time goes, which spreadsheet is never up to date. The real problem is almost never the one you told me on the phone.
I don't deliver the whole system after six months. I deliver the piece that removes the biggest pain right away, put it in people's hands, and we decide what comes next from there. If it isn't useful, we find out in three weeks, not a year.
A system that needs someone to press a button will stop sooner or later. Automatic checks, reminders that send themselves, scheduled backups: the boring work has to happen even when the office is closed.
Documented code, accounts in your name, nothing that depends on me to stay on. I stay to help the system grow, not because you can't do without me.
About
This site has two worlds, like my work: switch between Struct and Flux, or drag the line at the top.
I learned to code by studying: courses, documentation and real projects delivered to people who were waiting for them. I did the same with AI: months spent understanding how it's used inside a company, not how it's described in videos.
I've worked with few companies so far, and that's a choice: few problems, solved all the way, not twenty websites a year whose names I can't remember.
If I had to say it in one word: owner-builder. Not a technician who opened a VAT number, nor a salesperson who learned to code. My unit of measure is a business that runs; software is the lever.
Courses and documentation, then real jobs straight away. I learned by delivering, not by watching.
Not the toy: agents that answer customers, automations that run at night, models chosen also for what they cost.
I started with websites and ended up inside back-office systems, because that's where companies really lose hours.
A few companies followed closely, from the first meeting to the server that runs. On my own, end to end.
Lab
My experimental space. I test ideas, play with code and build strange things.
Contact
Half an hour on the phone and I'll tell you honestly whether it's worth doing, whether it pays off, and what it costs. If you don't need it, I'll tell you. It has happened before and it will again.
