Saurav Kumar


Hello fellow explorer! I'm Saurav kumar (a.k.a Rival) a software developer, but I'm not like other software developers. I'm not a genius with a pocket protector and a calculator. I'm just a regular guy who loves to code.

I'm not sure what it is about coding that I love so much. Maybe it's the challenge of solving problems. Maybe it's the satisfaction of seeing my code work. Or maybe it's just the fact that I can create something from nothing.

Whatever the reason, I'm glad that I have the opportunity to share my love of coding with you.

And since the lack of creative mind sometime makes me not productive enough, so it would be great if you have some interesting idea to share or need some help in your upcoming projects.

Always up to discuss high-level system design, improving the system and thinking the unthinkable
