    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.

    Sr. Systems Architect, Mathematician-Astrophysicist and Bio-Geneticist

    Canada - Last active: 12/10/2014 - Tests: 2 - Portfolio: 5

    My purpose is to lead, strategize, guide, direct and architect problem resolutions for individuals and organizations using self-sustainable philosophy and decision-making, in order to establish complete systems and processes of solutions that work. My vision is to ensure in every household, institution or establishment, intuitive and organic integration of real-time problem-solving becomes second-nature to the operating environment. I intend to achieve this using my unparalleled knowledge and application of the Synergy between Business Intelligence, Technical Excellence and Organic Sustainability. In other words, I solve problems, using fundamental building blocks that most people and organizations overlook, yielding solutions that can adapt to their environment in real-time. Problem-solving processing can lead multiple resolutions to several problems whereas "a solution" to a problem itself only, usually yields a new problem that need be solved with other solution(s) which may or may not be found within the given scope. This cycle can be vicious and critical but is easily overcome by what we call the "Process" or "Spiral" at Don Sigma Corp. This so-called "Spiral" allows us to solve problems that solve other problems by drawing Synergy between resolutions and fundamental building blocks. With this know-how and several other particulates of Don Sigma Corp.'s unique knowledge and technology at my disposal, you're just a contact away from experiencing your dreams come true.
