About

I am an optimistic focused on big goals with innovative solutions. Scientific research encouraged me to explore new territories and push existing limits by following up new leads.
I have passion to learn things beyond my conventional training in my spare time. I gained practical expertise on blogging, computer troubleshooting, software testing, cyber security, web development, personal finance etc. by self-learning. I also love to travel, capture photographs, listen to songs, watching cricket, reading books.
