Confidential

Java/C, C++ developer

Responsibilities:

• Was given the opportunity to work with Confidential an IT company on a part-time basis as I just started going to Osmania University for my Bachelor’s degree and so was given the task of doing a collaborative work with NIIT (National Institute of Information and Technology) on two specialty programs viz., GNIIT and Edgineer.
• The above programs demanded for people who have good programming skills in JAVA, .NET, C, C++ and C# to train new individuals in the above streams and I was given the task of tutoring them and also to work with these individuals on some end projects which occur every 3 months which included web design, code reviews and also debugging. Most of the work was done in J2SE.
• In these two years since some of the tasks which were handed to us were web design, we learned a lot on JavaScript and HTML and also employed them in our design for the final project which happens at the end of every one year. People who successfully obtain it will get a GNIIT certificate or an Edgineer certificate which is equivalent to that of obtaining a degree in a specific Major in a school.
• Most of the time we worked with Eclipse as a Development platform but we familiarized with some other platforms for future use.
• During this time I got another opportunity with Confidential, which involved some IT outsourcing, and professional J2EE Developer requirement so went ahead with that.
