Tutorials by Shailesh.
56 long-form lessons across three tracks. ~10 minutes each, with flowcharts and runnable code. Written like a senior engineer explaining over chai.
SQL, the way you wished you were taught
Eight lessons. We build a small Swiggy-style database from zero and end with the kind of queries seniors write at 2 AM.
Start trackJavaScript, finally explained without 47 frameworks
Eight lessons. From "what is var even" to "how the async stuff actually works under the hood." No Webpack, no Vite, no opinions on Redux. Just the language.
Start trackReact, the parts that actually matter
Eight lessons. We skip the historical drama and build the mental model that makes the rest of React feel obvious.
Start trackGo, for the backend job you actually want
Twenty lessons. Beginner path covers the language itself. Senior path goes deep on concurrency, the memory model, and the patterns interviewers love. Built for the senior backend interview.

ToolPop is built and maintained by Shailesh Kumar Singh, a software engineer based in Bengaluru. The site exists because online tools should not require an account, a credit card, or an upload to a stranger's server just to compress an image or convert a PDF. Every tool here runs entirely in your browser. Your files do not leave your device. There is no premium tier, no upsell, no plan to add one.
The tutorials section is newer. It is a slow, careful library of long-form lessons on SQL, JavaScript and React, and eventually more, written for people who want a working mental model, not just syntax to memorise. Each lesson takes about ten minutes to read and includes a flowchart, runnable code, and a quick-check at the end. All free.
The whole thing is funded by a single ad per page. That is enough. If anything feels off, write to singhshailesh2295@gmail.com.
