    Ronald R.

    Consultant, PM, Solution Arch, Sys/Net Engr, Developer, Designer

    Philippines - Last active: 09/27/2014 - Tests: 22 - Portfolio: 5

    I want to help organizations and individuals realize their vision by helping them build their systems and applications. I'm a senior developer, systems/network engineer, solutions architect, and project manager with over 17 years experience in the information and communication technology industry. I've held top management & technology leadership positions in several startup ventures in the field of operating systems & virtualization, mobile technologies, systems integration, and business applications. Two have been acquired at an early stage. I've recently worked as CEO for an offshore development & design outsourcing firm from Israel focused on web & mobile technologies and as CTO for a startup social gaming firm from Canada where I work hands-on with technology while mentoring small but growing teams. I've also led larger technology groups with over a hundred people sometimes from distributed locations. I've developed custom systems directly used by customers & end users. I've also developed systems as a subcontractor and publisher. My most recent projects include an emergency app on the Nokia Store, a geo-social app & a geo/social game on the Android Market, a JavaME app for a celebrity gossip magazine, a mobile/web ordering & delivery tracking system, and a web/mobile rock paper scissors tournament game. I've started my IT inclination as a computer enthusiast way back in college where I took on computer assembly and repair jobs as well as data encoding and desktop publishing to finance my education. Eventually, I learned programming in Turbo Pascal, Turbo C, DBase III+, and Foxpro/Clipper and took on small projects building software applications and database applications such as POS, inventory, and rental systems. Over the years, I kept myself updated with the changing trends and technologies, familiarize myself with new tools, methodologies & practices, and seek opportunities to utilize what I've learned commercially. I've setup systems for small businesses, small ISPs, and more recently small call centers during my spare time. All while playing a key role in the projects or companies I worked for.
