About me

Natural born software developer, side by side with a computer since I was ten. I love discovering how things work and learning the more the better. I enjoy facing challenges and solving problems. I am especially careful with details and the end result of my work. I am focused on backend technologies, performance and scalability.

Proud father of two kids, one dog and a cat. Music junkie and compulsive vinyl collector, I put some tunes at the Wurlitzer Ballroom some nights. I am sure I couldn't stand this world without music. Love sports, especially boxing, snowboarding and riding a bike. Sometimes I take decent pictures with my phone.

Recent Experience
November 2022 - Present
Head of Technology OMS/Core - Scalefast
Recently I was promoted to Head of Technology in Scalefast. I am responsible for the development the OMS (Order Management System) and the framework/core of the platform. Our main development language is PHP in its 8.1 version, for some things, a few, we use the Openswoole extension. We would like to be language and framework agnostic but now, we are using Slim 4 as glue for our APIs. We are strong advocates of PSR standards and very strict with code cleanliness and good development practices, SOLID, DDD and the clever use of design patterns are pillars of our development.
