About

I have always been amazed by the stories we can narrate using data. Though we are complex, mysterious beings who are often difficult to each other, I feel storytelling reminds us we’re all same in one way - curious beings with an itch to thrive Here is my story. Back in College, I was deeply curious about understanding how a blend of math and technology can help businesses solve problems at scale. I spend time reading business case studies to get intuitive answers to questions like - What is the exact problem statement and the pain point of customer? What decisions seems logical given the problem statement and the information a company has? What portion of results are driven by those decisions? How can we measure the impact of decisions? How do we build intelligent systems that automate such decisions? How can we best explain these mechanics to a non-technical stakeholders? As I progress through my career, I feel I have gotten better at answering these questions and guiding people around me to do the same. Having said that - I know that I can get better, solve bigger problems and impact even more people. I am glad to have the opportunities to do so. During my time as Senior Data Science Consultant (AI/ML) at Fractal, I leveraged by skills in Root Cause Analysis, NLP, Pattern Recognition, Insight generation and Generative AI to build services and deploy features that delivered strategic value of 20 Million $, improved NPS by 25% and prune reported customer issues by 20%. While serving as Analyst at Retail/Ecommerce giants like Flipkart and Lowes, I got the opportunity to work on exciting problems such as inventory management & supply chain optimization, retail customer segmentation, customer churn, product recommendations, marketing campaign analysis. I delivered solutions that reduced inventory storage costs by 10 million $, improved In-stock levels for high demand items by 9%, increased website conversion rate by 12% and saved 60+ work hours every week. While serving as Senior Data Analyst at Target, I lead a team of data analysts to migrate and upgrade 50+ big data pipelines by leveraging business acumen and optimization skills. I also created 10+ automated Dashboards for Supply Chain Directors & Managers which enhanced KPI visibility for the Middle Mile transportation team. Right now, I'm building a portfolio of End-to-End projects as a Data Scientist with Gen AI expertise who can build, orchestrate, evaluate and monitor AI powered systems to deliver massive value for companies in the Retail, Ecommerce, Telecom and Healthcare industries.
