About

Ever since I was a little kid software development has been my passion. I still remember sitting in front of a really old computer running on windows 98 and using paint to draw stuff and wondering how the hell is this thing even working. I went through the basic tutorials of C and learned how to print the legendary "Hello World" on console and then without any help figured out to print "Hello, Danish" for the first time and feeling like the king of console 😂 then creating my very first own calculator and refusing to use the inbuilt one and every time running my own console program to calculate stuff (it was godlike feeling😎). Fortunately, my elder brother had the same spark for coding (even more than me) and taught me many things. In High School, most of the time I used spent in computer labs on that blue screen turbo C++ perfecting my calculator and thinking one day it will be used by everyone in the entire school. This passion carried me through my education at Jamia Hamdard. Here there were more resources available to me than I ever could have imagined. I studied new languages like Java, Python learned how web pages worked and get served on networks, why HTTP always comes in browsers, and why the hell some random numbers (I.P) and a website name (of the same IP) gives me the same web page. The more I learned about the web the more I started liking it and wanting to learn everything. Till now this passion remains with me. I haven't even explored all the surface and there is yet a vast ocean to discover. And for this, I am very grateful.
