Vivek Pandey's Homepage

Hi, my name is Vivek Pandey. I look approximately like this:

I am a Computer Engineer, with amateur interests in Mathematics and Chess.

For past few years I have developed an interest in running and cycling.

I am married with two noisy kids.

Professoinally I was the CTO at Simpl till Sep 2025. When Simpl closed down I decided to take a break and decided to study LLMs in detail.

I periodically write - mostly on technical topics but sometimes on other topics.
