§ 02 · Profile

The short version.

Curated by the man himself

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.

§ 03 · Career trajectory

From the trading floor to a dev tool.

A non-linear path through enterprise tech, finance and startups — roughly chronological, occasionally honest.

    Senior Engineer

    HP · Accenture · Deutsche Bank

    Years inside large engineering orgs — distributed systems, financial tooling, the kind of code that has to keep working at 3 a.m.

  4. 04

    2018 — Now

    Computer Engineering

    EPSEVG · UPC

    Universitat Politècnica de Catalunya. Where the math, the logic and the love for clean recursion got formalised.
