Sampada Wagde
I am a software professional with more than 13 years of industry experience in the financial services sector. Driven by the quest to learn, I am a researcher at heart who believes in leading by example. When not glued to my laptop coding or reading/writing articles, I can be found glued to my laptop watching a movie. Outside of a computer, I immerse myself in fiction and music. But most of the time, I relish playing parent to a toddler and two dogs.
Here's what I've written (so far):
