What I build
Three things, above all: software tools for the day-to-day work, automation of what is done by hand today, and data management systems so that every piece of data has one place and can be trusted. Specifically:
- Web and mobile applications: one codebase that works on the phone, the tablet and the browser.
- Management platforms: budgets, orders, customers, bookings, invoicing — with approval flows, permissions and audit trails.
- Data management systems: the data model, the database that holds it and the dashboards that read it — one version of each figure, with no spreadsheets running in parallel.
- Integrations and APIs: systems that don't talk to each other and should; data that flows without re-typing.
- Automation: the repetitive work — reports, alerts, handoffs between systems — done by the machine.
- Digital product: from the MVP that validates an idea to the SaaS in production, cloud infrastructure included.
Real projects
No need to imagine the result: these projects are built end to end by the same person who would build yours.
Management platform for restaurants: bookings with optimized table assignment (operations research), service calendar, POS, Spanish fiscal invoicing (Veri*factu / TicketBAI), catalog, staff and subscriptions. Mobile and web app in 26 languages on serverless infrastructure.
Multi-company budget management platform: budget versions, change requests with approval, notifications, exports and a full audit trail of every movement. Multi-tenant, with corporate authentication.
Apple Watch app that generates the access QR code for a sports club right from the wrist: secure session in the Keychain, automatic renewal when the code expires, and one-tap access without taking the phone out.
Prototype for protecting web content from scraping: a Rust proxy serves the page with per-session empty fonts and repaints the text as a rendered image — unreadable for bots, identical for people.
How it works
- Nothing off the shelf. Every project is designed from scratch for your case — your process, your rules, your systems.
- Short diagnostic with fixed scope and budget; small, frequent deliveries from week one.
- You get the code and the documentation. So you can maintain it: your project is nobody's hostage.
- One person, no middlemen: the person who understands your business is the one who writes the code — and answers the email.
Is your problem on the shop floor?
If what's stuck is production — the plan, the rush orders, the shifts, the shop-floor spreadsheet — that part has its own section: a Tuesday at your plant.
