Does a Free Portfolio Website Actually Help Your Career in India?

I spent ₹8,000 on a portfolio website in 2019. Wasted money. Not because portfolio websites are useless — they're not. But because I built it wrong, uploaded it to a domain I couldn't remember, filled it with projects nobody cared about, and then abandoned it for two years. When I finally needed it for a job switch, the website was broken, outdated,…

The Free Tools Trap That Wastes Every Junior Analyst's First Year

When I started as a data analyst three years ago, I thought I had to master everything. Excel, Python, Tableau, SQL, Power BI — I signed up for paid courses, bought subscriptions I barely used, and convinced myself that spending money on tools would make me better. Spoiler: it didn't.

Usually it's someone's kid, or a cousin who just finished their degree, or someone I ran into at the local chai shop who heard I work with data . "Bhaiya, sh…

Are You Actually Using AI or Just Playing With It?

Last month, I sat across from a junior analyst at work — sharp guy, good with Excel — and asked him how he was using ChatGPT for his reports. He said, "I tried it once but it wasn't that good." When I dug deeper, it turned out he'd asked it to "write me a financial analysis" and copy-pasted whatever came out. That's not using …

GitHub Is Not Just for Developers—It's How Modern Work Gets Done

I didn't understand GitHub until I stopped thinking of it as a tool for programmers. Six months ago, a colleague at Morningstar sent me a GitHub link to review some analysis code. I opened it expecting to see some intimidating terminal nonsense. Instead, I found myself looking at a neatly organized folder structure, comments explaining what each piece d…
