Living and working in Ireland since 2014
I’m passionate about new technologies since the first contact with my ZX Spectrum+ and its BASIC tutorial and now I work as an architect, technical lead, etc.
Since 1998, I have worked on more than 50 large scale projects, mainly all in Java, Scala and related technologies.
During the course of my career, I have been in a lot of different technical positions, from senior software engineer to technical leader and architect shared with team manager and project manager responsibilities.
I bring to every project experience, agile methodologies and desire to be with a great team. No one is more Java / Scala evangelist and advocate than me, but my experience taught me that not everything is nails.
Good software is only possible with happy developers in a great work environment
I'm always looking for challenges, no matter the size of he company. Currently, I work from the comfort of home (100% or almost) to not waste my energy in commutes and investing more time in my projects and my family.
From 2015 to 2016, I was part of a team (two developers at the beginning) with the challenge of being part
of the design and implementation of the Dun and Bradstreet’s Search Engine. Others teams tried it
before with only part of the data set, but they did not achieve enough performance to be able to sell the service.
In no more than five months, we released an API (including the ETL, indexing pipeline, etc) serving 350millions of
records with more than 20 different filters.
My most worthy project has been my own startup project: www.simplexportal.com,
a CMS / ecommerce SAAS platform developed from the scratch, where I demonstrated that usability and
simplicity are compatible with flexibility, power, performance and the use of standard technologies.
In 2001 I was working in the first enterprise project base in Java/J2EE in the Santander Bank. My share
in this project was recompensed with a 2 year contract in this company as a Java technical leader in one
of the more important departments (The Treasury Department).
Computer Systems Technical Engineer Bachelor Degree (3 years / 1998) in Universidad de Extremadura (Spain)
I need to present the capstone project, but before, I have many more important things to do.
