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.

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.

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.

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.

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.

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.
Real projects
Each one started from someone's problem. Open it to see how it was built.
