Hi, I'm Pritam.

I'm a .NET developer and team lead with 12 years of experience, currently preparing for interviews in system design, AWS, Python and AI.

Why I built this

I'm a visual learner. Reading notes didn't help me picture how things work, so I started turning each topic into a small page I could click through and play with.

It helped me learn faster, so I decided to share it. If you're preparing for interviews too, I hope this is an easy place to start: understand a topic in a few minutes, interactively, then go deeper.

How to use a page

1. Read the short bullets at the top.
2. Step through the walkthrough.
3. Play with the examples, then try the quiz.
