Your Portfolio Website Doesn't Need to Cost Money — It Needs to Exist

Three months ago, I realized something embarrassing: I was a data analyst at Morningstar who couldn't show people what I actually did. Sure, I had a LinkedIn profile. But when someone asked, "Can I see your work?" I had nothing. No projects. No case studies. No proof that I could turn messy datasets into readable stories. Just a resume that lo…

Two Years at Morningstar Changed How I Pick Data Tools — Here's What Actually Stuck

When I first moved to Mumbai from Kalyan, I was convinced that expensive enterprise software separated the "real" data analysts from the amateurs. My first week at Morningstar, I watched senior analysts throw around tool names I'd never heard of—Tableau, Power BI, Alteryx—and I assumed that's what I needed to master to be taken seriously. Th…

Machine Learning Isn't Magic — Stop Waiting for It to Change Your Career

Forty-five minutes of data entry work. Forty-five minutes I didn't have. I was supposed to be home by 11 PM. I had a personal finance article due the next morning. My mom had calle…

Two Years of Watching Developers, One Tool Changed Everything

The Kalyan-to-Mumbai local train at 8:47 AM is a specific kind of crowded. You're wedged between someone's backpack, a vendor selling chai, and usually at least three people checking their phones. Last Tuesday, I was standing near the door when a guy next to me opened his laptop — risky move on a moving train — and started scrolling through something ca…
