Ruby on Rails Consulting
I am an independent Ruby on Rails consultant with over twenty years of professional programming experience. Author of Zeitwerk, and member of the Rails core team since 2011.
I am honored to have been presented an Outstanding Performance Award in the Fukuoka Ruby Awards 2022 for Zeitwerk.
Also honored to have been awarded a Ruby Hero Award in 2010.
Companies I have had the pleasure to work with since I started as an independent consultant:
Priority Support Subscription
By subscribing to Priority Support, your company can contact me any time for code reviews, design advice, joining discussions, etc.
Please, contact me at email@example.com.
Full-time collaborations have a flexible monthly dedication of at most 100 hours per month. I work as an external consultant for your company. Normally, in this model of collaboration there's some kind of exploratory problem to be solved with thought and care. These often run parallel to the day to day of the company.
Please, contact me at firstname.lastname@example.org.

I have a degree in Mathematics by the University of Barcelona. Have worked in a few things ranging from a small music shop to proofreading math textbooks for six years. I have been into computers since I was a kid, programming has always been a passion, and switched to being a programmer for a living after doing one year of PhD.
I spend most of my spare time contributing to open source. Open source is all about knowledge sharing and collaboration, principles I strongly believe construct a better society.
I have been into Ruby for a long time. As highlights, I am the author of Zeitwerk, a member of the Rails core team since 2011, and the author of Rails Contributors. I am honored to have been presented an Outstanding Performance Award in the Fukuoka Ruby Awards of 2022 for Zeitwerk, a Ruby Hero Award in 2010, and to be part of the team who organised the European Ruby Conference 2009 (EuRuKo 2009), held in Barcelona.
I was also into Perl for some years. I am a CPAN author, and former leader of Barcelona.pm. Back in 2006 I published an article about the intricacies of newlines for O'Reilly's ONLamp.com. Also taught a Perl semester for seven years at the University of Barcelona as a part-time lecturer. That was vocational, I did it in my spare time.
Reading is one of my passions. I keep a listing of the books I read.
