I’ve been building for the web for more than 25 years. First with PHP, and since 2013 with Ruby on Rails.
I care about software architecture, clean code and scalable solutions that deliver real business value. Remote since 2014: distributed teams, asynchronous collaboration. I’ve taught 2,000+ developers on LinkedIn Learning and write about software design on DevelClan.
*nowHEAD → mainWriting on DevelClan and going deeper into software architecture and infrastructure.

*2000Merged into my first job in October, thanks to a recommendation from someone I met on #php: a train-management web app for a Catalan railway, in ASP. On day one a stack of notes landed on my desk: I was teaching a JavaScript course the following week.
