I am a software developer with over 10 years of experience. I have majorly been working with Python but recently got to use Golang. I am curious about technology and love to tinker with it to find out why it works and how it works. This also leads me to get frustrated at times when I am unable to find good helpful material on the subjects. I believe that getting into new technology or understanding the fundamental concepts should not be hard and more beginner friendly material should be accessible to everyone. And so I am trying to give talks based on what I believe might be highly valuable to beginner/intermediate developers. I have been fortunate enough to give a talk discussing goroutines at GopherCon SG and based on the feedback I got for the talk, I feel I am on the right track. This is my way of giving back to the community. Link to my GopherCon talk - https://www.youtube.com/watch?v=64XXaIC-K74
