Free Tools Won't Make You a Better Data Analyst (But Knowing Which Ones Matter Will)
I spent my first six months at Morningstar buying every paid tool I could justify. Tableau Public (free, but limited). Looker Studio (free).

I used to think GitHub was some exclusive club for Silicon Valley engineers and people who had "developer" in their LinkedIn headline. You know, the kind of place where people pushed code at 2 AM while drinking cold coffee and arguing about semicolons in Slack channels. Six months ago, I didn't have a GitHub account.

5 Data Skills That Actually Matter in 2025 (And How I Use Them Every Day at Morningstar)
I used to think being a data analyst meant being good at Excel and knowing SQL. That was 2019. I was wrong. Three years into working at Morningstar, commuting from Kalyan to Mumbai five days a week, I've learned that the job has shifted. Completely. The analysts getting hired now—the ones with offers from ICICI Bank, Goldman Sachs, and startups paying ₹…
