Full Stack Engineer

About Me

I’m an engineer with 4 year experience creating and building full-stack applications, participating in all the phases of software development. I was the only developer for 3 years in my last job. I’m mainly a Meteor full-stack developer, but, I have always thought, that what I can learn is more important than what I already know. I’m looking for new opportunities, ideally working remotely in a startup.



R&D Full Stack Engineer / Lead Full Stack Engineer

I was the only full time developer for the first period of 10 months and then I became the only developer and web engineer in the company working hand to hand with the CEO to publish apps and doing the graphic design.

3D Engineer (intern)

November 2014 - December 2014

This experience allowed me to continue developing my artistic and design skills.

  • In order to strengthen my level of French to work I did an internship here and I made a 3D marketing animation and designed some 3D molds for wooden skateboards.


IoT Embedded Systems Engineer (intern)

May 2014 - September 2014

I did this internship in order to do the final project of the Master in Embedded Systems Engineering.

  • I implemented an IoT application to control and monitor industrial washing machines remotely.
  • I implemented both the device software IoT part and the desktop IoT application using Device Cloud by Digy as the web IoT platform.


Design and Development Engineer

September 2011 - March 2013

Even if my main mission was to design 3D mechanical parts, I also developed some software tools that helped all the mechanical engineering team to save time producING 2D plans. I developed this software using VBA for SolidWorks and it helped us to reduce the time from a day to about an hour each time we needed to produce plans.

  • I defined the electronic part specifications and was responsible for the relationship with the electronic part colaborator company.
  • I designed 3D mechanical parts, specifically the lock between the bike sharing base and the bike, and also produced prototypes. I found and manage the suppliers for the production of this part.
  • I tested and did some electronic maintenance of the system.
  • We were a startup that won the public contest for the bike sharing system in San Sebastian.


Control Software Support Engineer

July 2007 - Jun 2009

  • My coworker and me designed the first auto-diagnosis algorithm for the wind turbines. This new algorithm was part of the preventive and corrective maintenance.
  • I analyzed and did the analysis and error detection in control software for wind turbines.


Continuous Improvement Process Engineer

March 2004 - May 2007

  • I implemented some advanced VBA applications for Excel and Word in order to reduce the time managers spent calculating the most significant weekly statistics to analyze the performance of the mission of their departments. I helped each manager save 2 hours / week.
  • As the responsible of some improvement process projects like 5S, Lean Manufacturing and 6 Sigma projects I was able to develop my team management skills and I found that leading by the example was the better way.
