About

In school, I am good at solving maths problems by looking at answers. Although it's not a good education practice. But that helped me in my professional career to solve different problems and gain knowledge. I am an Information Technology graduate and passionate about learning new technologies and helping teams to grow. Along with professional work I enjoy gaming, meditation, and exploring places. I want to share my knowledge and apply the best practices acquired through the years. Upgrading the application to a newer version has challenged me to solve issues differently and get to know about it more in-depth. I do not like pushy people. If you are nice, I will go out of my way to help you. I enjoy helping people and I love to learn about new technologies... I am good at: Networking, Programing, Administration, Firewall, Integration, Web Development, Front-End Development, Back-End Development, Quick Learning.
