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 designed and developed software for prestigious companies and organizations 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, later I had the opportunity to work at Genome, an award-winning experiential digital agency and startup accelerator where I created iOS and Android MVPs for incubating startups and created web experiences for United Airlines, EXXON & Mobile and Verizon. I've had the chance to work in several countries and cities such as San Salvador, Sao Paulo, Washington DC, Miami and New York.

Today, as Senior Software Engineer at BeenVerified.com I'm in charge of developing, maintaining and improving all BeenVerified's Android apps, including apps from it's sister brands PeopleLooker, NumberGuru and Ownerly. I volunteer organizing GDG San Salvador's meetups (the official Google Developers Group chapter in San Salvador, El Salvador).

As you can see I love to code, love meeting and chatting with people, attending conferences and meetups, participating in hackathons to learn new things and share the little knowledge I have with everyone so it multiplies and benefits the largest amount of people.

When I'm not coding, I enjoy reading, creating new talks to speak at tech events, taking long walks in the outdoors with my awesome dog Duke (yes!, named after the cute Java programming language mascot), playing the occasional video game, practicing biohacking trough nutrition and having a healthy lifestyle, cooking new dishes (#ChefOscar), binging on Netflix, trying new restaurants, building robots, traveling, etc.
