The short version.
Francesc grew up between three languages and a strong opinion that software should do more with less.
He studied Computer Engineering at EPSEVG · UPC and spent the early years of his career inside HP, Accenture and Deutsche Bank, learning what large-scale systems really cost in people-hours. The kind of lessons you only get from being on-call.
In 2023 he co-founded Totalum, a low-code platform that turns business ideas into running software. Along the way he ships side projects, talks to founders, and keeps a soft spot for elegant recursion and well-named functions.

Universitat Politècnica de Catalunya. Where the math, the logic and the love for clean recursion got formalised.
Things he built instead of sleeping.
Three projects out of many. The rest live as private repos and half-finished sketches.
Totalum
A low-code program creator. Design schemas, write logic, and ship a working product before lunch.
VisitOxos.es
Multi-wallet payments wired into a clean shopping experience. Built when paying in crypto still felt clumsy.
VisitTres en Raya — Live
A real-time multiplayer tic-tac-toe server in Node.js. A small project that explained sockets better than any book.
