About Me

Hey there! 👋 I'm that mechanical engineer who fell head over heels for the world of data. Why? Because I believe data isn't just numbers – it's stories waiting to be told and problems waiting to be solved. Let me share a bit about my journey! 🚀

The Tech Journey

From mechanical gears to data pipelines – quite a pivot, right? My fascination with data started when I discovered its power to simplify our lives. Now, I'm that enthusiast who turns complex data puzzles into "aha!" moments. Think of me as a data alchemist, transforming raw numbers into golden insights! ✨

Learning & Growth

"Break it till you make it" - that's my learning mantra! I dive headfirst into new technologies, embracing the challenges and occasional chaos. Those moments when everything breaks? They're just pit stops on the road to mastery. The best solutions often come from those "what if I try this?" moments! 💡

Active Mind, Active Life

Just as I juggle datasets at work, I love keeping multiple games in play - from smashing shuttlecocks in badminton to cricket matches that go down to the last ball. These sports have taught me that whether it's code or court, strategy and persistence win the game! 🏸🏏

Creative Downtime

When I'm not crunching numbers, you'll find me lost in books or binge-watching shows. It's amazing how often a random Netflix session sparks a brilliant solution to a coding problem! Because sometimes, the best debugging happens when you're not debugging at all. 📚✨

I bring together a mechanical engineer's precision, a data scientist's curiosity, and an athlete's determination. Whether it's tackling complex data challenges or serving an ace in badminton, I'm always ready for the next exciting opportunity. Let's create something amazing together! 🤝
