Porto Metro timetables on your phone, in 7 languages and even with no signal inside the tunnel. An independent app that I designed and maintain end to end: from the interface to payments, from timetable import to the server.
Handmade shop · in production
Online shop for handmade baby clothes, toys and accessories, with catalogue, cart, payments and order tracking, in 5 languages and with no tracking cookies.
Interface, backend, payments and operations: I do it all, so every decision fits the others.
Everything I show is live, with real payments and running every day.
No tracking cookies and no unnecessary data. Location, for example, stays on the phone.
Installable apps, fast on phones and, where it makes sense, working offline.
I also build for others. See services or get in touch.
