Bio

In 2004, I developed my first large program, a Platform-based Video-game in Pascal for the school’s scientific fair where it was awarded “Most popular project”, and in 2005, in collaboration with the Electrical Engineering school, a Basic domotics system in C++. I graduated from High School with a Computer Programming degree in 2006. In 2007, immediately after High School graduation and while pursuing a Bachelor’s Degree in Engineering in Information Systems, I started a full-time job, first as a Support Engineer at Intel Corporation, and later at Hewlett-Packard in the HP Software department. Between 2007 and 2009, I developed a Store Management system for a Costa Rican mid-size store using Visual Basic and MySQL. In 2010, the global head of HP Software Services and Solutions awarded me for my “Dedication and Professionalism”. For my graduation project, between 2011 and 2012, I developed an Inventory & Order Management system for a major hospital using ASP.net and MS-SQL. I completed my Bachelor’s Degree in Systems Engineering in 2013 from National University of Costa Rica. In 2013, I developed a cloud-based Client Visits Management & Logging system for a healthcare product distributor. Between 2010 and 2014, I developed a series of smaller projects in Perl, Python, Javascript, and PHP, besides my regular work for HP Software. In 2014, I took a series of classes as part of a Masters Program in Project Management from Costa Rica Institute of Technology, and in 2015 a Licentiate’s Degree in Computer Systems from Fidélitas University. In 2015, I started working for Aruba Networks as an Embedded Software Engineer. In 2016 I was awarded by the VP of Switch Software for my “Dedication to making our products a success”. Between 2016 and 2021, I made major contributions to the ArubaOS-CX Network Operating System and the Continuous Integration platform, including containerization research, software optimization, plugabble mechanisms to facilitate root-cause analysis, high-availability and virtualization. In 2021 I started at Microsoft, this was a significant shift. I had to move from a mostly Linux-embedded, C-based development, to a mostly Windows-cloud oriented, C# development. During this time, I’ve made contributions in Service Availability, Resource Fungibility, Stack Modernization and Virtualization space.
