About

Problem-solving and programming enthusiast currently working as a Software Development Engineer at Amazon AWS S3, the largest distributed system alive. It has been a great learning experience so far. Earlier worked as an Advanced Data Science Intern at ABB Inc. involving Time Series forecasting using R/Apache Spark on Microsoft Azure and as a Decision Scientist at Mu Sigma Inc., one of the few Indian unicorns and India's largest Big Data Analytics firm, where I got the experience of a Data-Driven approach to Business problem solving and BigData. Algorithm Design, Machine Learning on Big Data, Parallel/Distributed Computing are my major areas of interest. Statistics, extensive experience with C++, R and SQL are my key competencies besides good working experience with Hadoop ecosystem(Apache Spark/Hive), Python and Java. In free time, you'll find me either -Learning a spoken language and exploring about various accents and dialects (or) -With a backpack and my Sony Alpha
