Supplementary courses to consider to boost ones profile

[aceacharya]

I am an Electrical Engineer, currently working in India with a work experience of 4 years in the manufacturing sector and will be applying for next years term. What kind of supplementary courses should I consider to boost my profile, considering my high school science and engineering graduation background. Also, please state if any such recognised course would be available online so that i may take them at my convenience.

Thanks in advance
