About

I'm a developer, but what hooks me is what happens around the code: who will use it, why they need it, how to make it work. I've built for an international artist and a barbershop, designed a proposal for a law firm and created my own nightlife app.

Experience

The routeso far

  1. —

    ParyUp

    Own project: product and development

    My longest project: ParyUp, a nightlife app with its own mobile app and backend. I went to Sutton Barcelona to understand the venue side and, separately, when I saw the value was in the group of friends, I rebuilt the product. It never launched.

  2. —

    Hektor Mass

    Freelance: website for an artist

    My first real client, who came through ParyUp: the Hektor Mass website, live in production. I iterated on the changes he asked for and today he updates his tour dates himself.

  3. — now

    BeDisco

    Event lighting, set-up and operation

    Occasional work: covering for the technical team when needed. It isn't what I do for a living, but it showed me how an event works from the inside and what working live means.

  4. —

    Toga

    Product proposal and prototype

    I watched the day-to-day of an employment lawyer, wrote the value proposition and built the clickable prototype of Toga.

  5. —

    Zig Zag

    Product for a real barbershop

    I sat down with the owner, turned his day-to-day into requirements and built Zig Zag: bookings, CRM and loyalty. A finished, documented product; the owner never adopted it.
