    Microsoft MVP | C# Desktop | ASP.Net MVC | JQuery | EF | WCF | SQL

    Philippines - Tests: 1 - Portfolio: 6

    In my 10+ years on the IT Industry, I have participated on different kinds of projects that demands specific roles. There are instances in which I was the one to design the architecture of the application and manage its implementation. While there are some that requires me to follow an existing architecture and work with other developers on the implementation. This shows that I can either work alone and manage my own resources or be a part of a development team. I have already helped companies develop different types of applications ranging from simple dynamic websites up to a full-blown Desktop/Web application using the .Net Framework. I primarily use C# as my main programming language. One of the most important thing on a virtual work environment is to establish a good communication with the client. I do this by having a daily/weekly meetings to keep the client up to date with the things that I’m working on. It’s already been 4 years since I started doing Telecommuting (Home-Based) Jobs. And during that time, I have learned how to manage my time efficiently and deliver products as expected by the client.
