A long time ago in a Galaxy far far away… just kidding!

Hi! My name is Oscar, I started coding at 12 while attending middle school, at 18 founded my own software consulting firm and with it advised several domestic and international customers on for their IT needs. In college I studied Computer Science.

A little bit down the road, I became interested in Java and founded JUGsv, El Salvador's first Java User Group, then several Google technologies caught my attention so co-founded El Salvador's first Google Technologies User Group (formerly known as GTUGs, now GDGs) where served as Speaker/Blogger.

I've developed, designed and/or architected software for companies and organizations of all sizes such as DataSoft, Avianca/TACA Airlines, EQUIFAX, ACF Technologies, the Inter-American Development Bank, co-founded and led mobile development at Geopon, a mobile commerce/advertising startup, after some time, had the opportunity to work as Director of Technology and Full-Stack Senior Developer at Genome, an award-winning experiential digital agency and startup accelerator where I helped to create several iOS and Android MVPs for incubating startups and collaborated in the creation of web experiences for clients such as United Airlines, EXXON & Mobile and Verizon, later as Senior Software Engineer at The Lifetime Value Compnany, I've been in charge of developing and maintaining all Android apps for their BeenVerified, PeopleLooker, NumberGuru and Ownerly brands. I've had the chance to work with multi-cultural teams, on-site and remote in several cities such as Sao Paulo, Brazil, San Salvador, El Salvador and Washington DC, Miami, FL and New York, NY in the United States.

Today as the Founder and CxO at Real Action Software I am dedicated to help established and startup companies around the World with their technology R&D, software and hardware prototyping, development and app maintenance needs. I volunteer as the organizer of GDG San Salvador (the official Google Developers Group chapter in San Salvador, El Salvador) and travel the World speaking about various Technology topics.

I love to code, be involved with the tech and dev community, attending conferences and meetups, participating in hackathons, learning new things and share the little knowledge I have with everyone so it multiplies and benefits the largest amount of people possible.

When I'm not coding or traveling, researching tech topics for creating new talks to speak at tech events, I enjoy reading, taking long walks in the outdoors with my awesome dog Duke (yes!, named after the cute Java programming language mascot), playing video games, practicing biohacking trough nutrition and a healthy lifestyle, cooking, pouring capuccinos (not so good with latte art yet, but I'm getting there), binging on Netflix, trying new restaurants, building robots, etc.
