About The Developer

I'm Karan Rajput KK — blogger, SEO expert, affiliate marketer, and self-taught developer. While most know me from KaranKK.com for blogging and SEO content, I have been quietly building free online tools since 2021 that solve real everyday problems.

Each tool is built from scratch using HTML, CSS, and JavaScript — no heavy frameworks, no paid APIs, no bloat. Fast, clean, and mobile-friendly. Every project is deployed on multiple high-authority platforms to maximize reach and reliability.

These tools also serve as a reference for my work — each deployment on GitHub, Firebase, Cloudflare, Vercel, and Netlify acts as a live proof of what I build.
