About the Author

My name is Harcharan Singh. I'm a Software Developer from Punjab with 12+ years of experience, specializing in providing online/offline solutions by creating web, desktop, mobile, and IoT solutions for businesses and industry.

I love coding. Most of my time is spent creating solutions for challenges I face during my programming work. On weekends I maintain and enhance ongoing open-source projects and libraries. I spend my free time contributing to the coding community — either with open-source solutions or through Bit&Bytes.

I avoid social platforms to make the most of every free moment. You can follow me on bitnbytesio @ GitHub.

Tech Stack

I primarily work with Node.js, PHP, Go, JavaScript, Angular, React, and C. From backend APIs and system-level programming to full-stack web applications and IoT firmware.

Notable Projects

• node-input-validator — A validation library for Node.js with support for custom rules, localization, and nested objects. Widely used across Node.js projects on npm.
