Oh, hey there! 👋
I'm Julio (with a hard j, please), thanks for visiting this "personal" site!
I'm a Senior+ Software Engineer with 15+ years of Ruby on Rails. Until May 2026 I was Principal Engineer at RubiconMD, where I spent 9+ years guiding a healthcare platform from its startup days to its integration into CVS Health, and co-founded our Platform Engineering initiative.
I'm now open to new opportunities: full-time or contract, senior and above, in platform engineering, technical leadership or hands-on development. Fully remote, and happy to travel. Read my resumé or drop me a line.
What I do
Since 2011 I've been working in web development, with a strong specialization in Ruby on Rails, both as a full time employee and a contractor, and fully remotely since January 2014, for both UK and US companies.
What motivates me
When it comes to work, I'm strongly motivated by projects with real positive social impact, technology at the service of the people, learning and applying new skills and concepts, patterns and techniques when coding, architecture and systems design, clean code, taming legacy codebases, teaching and mentoring others.
Outside work
I was born in Sanlúcar de Barrameda but have been living in Seville (Spain) since 2002.
I share my life with Julia, and together we take care of our cats Perla and Pancho. In my spare time I love playing video games and playing bass for the progressive metal band CARVING COLOURS (since 2010!), with which I've independently released a couple of albums, which are available for listening and purchase (wink, wink) on Bandcamp as well as on Tidal or Apple Music.
