I learned by
building my own projects.

I started in a small town in Uttar Pradesh, with questions about how websites found their readers.

That curiosity led me to SEO, publishing, and eventually OnlyLoudest. Working on my own sites gave me a reason to care about the content, the audience, and what happened after someone clicked. I bring those questions to the businesses I work with today.
