Can someone recommend which is the right option for 2 years experienced .Net developers to enhance their technical skills whether .Net Certifications or work experience in Open Source Projects apart from their day time job.
Say currently I am working in a company and devoting my free time during weekends to open source projects. Now if I specify this open source experience in my resume for my future jobs, will the open source experience in resume have any negative impact as I am also working in a company during the same period?
Since i am working in a company i can do only one among them due to time constraints. So really like to have your suggestions before i proceed.
