Sachin Kumar Singh

A computer engineer by degree and a passionate researcher, generally curious about how things work, a programmer, applying my knowledge to solve some of the difficult problems. Majorly worked in Multimedia Security.

My goal is to be part of this changing world of technology and actively contribute back to the community.



Hey, thanks for stopping by

Two things I firmly believe, first imagination and second, everything is paradoxical, especially us in a particular context. Our imagination creates our future. It ignites passion. It influences everything we do, think about, and create. We are the "paradox." We want to be happy when we think of things that make us sad. We are ambitious, but we are lazy. We sometimes don't like ourselves, but also we love who we are.

The thing that inspires me the most are scientists and their scientific stories. These stories taught me what impact imagination and curiosity could make. Maybe for most of us, science is just facts, but for scientists, it is the perspective of life. I have a strong passion for research, despite not being in a research peer community, I am actively doing it from the last one and a half year and contributing to multimedia security. I enjoy research indulgence because it challenges me, and it highly motivates me to do something out of the box. I am also a self-taught graphics designer, designing taught me "Hard work is universal, it doesn’t matter how creative you are, you need to work hard to bring that creativity out of you." 

I am incredibly passionate about learning new things. In my view, I am sarcastic and hilarious, but I also believe that most people find me obnoxious and annoying. I told you about the "paradox." ​

Hope you enjoyed small peek into my world !
