## Technical Content Writer @ IncludeHelp

I'm **Indrajeet Das**, currently pursuing **B.Tech in Computer Science from Delhi Technological University (formerly DCE)**.

I have good programming skills for C, C++ and Java and also an android developer.

Apart from that, I love to solve problems and puzzles and can spend hours on them. I enjoy reading books and play table tennis.

I believe that **"Success is no accident. It is hard work, perseverance, learning, studying, sacrifice and most of all, love of what you are doing or learning to do."**
