Lead Data Scientist

Only move forward with creating a product that will be “above the bar.” – Brian Lawley

This quote resonates and sums up the significant pivot I’ve made in my career from an IT professional with more than 2 years of work experience to a product manager at one of India’s leading private sector bank with over a year of experience and constantly contributing to building scalable solutions for a beautiful future.

It has been a thrilling and satisfying experience!

I had the opportunity to work with TCS in supporting corporate decision-makers and have proven success in improving processes and complying with procedures to exceed company and client objectives. 

During my MBA, I had the stellar opportunity to intern with the chief regulatory body of India, Reserve Bank of India (RBI), and contribute to the nation's Fintech space.

MBA at IIM Kashipur had given me the right propellant to nurture my mindset for strategic thinking and product strategy, and hence my team and I made it to the semi-finals of TATA Steel-a-Thon Season 10 (organised by Tata Steel). 

My very first stint at a product management case competition held by IIM Bengaluru turned out to be a moment of pride when I was announced the Winner for providing innovative enhancements and features that go beyond conventional tutoring experience for a peer-to-peer learning platform.

I’m constantly spearheading enhancements in the personal loan journey at Axis Bank by surging funnel conversion by 3x to reduce complexity in the landing landscape.

Apart from this, I’m also a professional illustrator with several national and international publications. My hobbies include travel, music, and illustration. I’m also a trained Classical singer.

When not working, you’ll find me making products and merchandise for my own stationery shop, painting, journaling, playing the synthesizer, or doing abs training.
