About

I want to share with you my knowledge, that I have gained all my life. I like to see every task in your day to day life as an interesting problem to solve, and if you can understand the requirements, solving for it can become somewhat intuitive. I try to explore certain aspects of day to day life and how I can make them easier for you. This involves daily hacks, tutorials, innovations, new discoveries, experiences and all the stuff I find amusing. As a software engineer myself, I also believe that good problem solving skills can help you overcome most of the barriers in life. Programming is one of them. If you know how to approach a problem, writing a code for it in any language could be a very typical task. With this channel I aim to focus on the way to solve a problem efficiently rather than just its implementation.
