About Siddhesh Yadav
As a Software Development Engineer 1 at Amazon, I work on AWS EMR, a cloud-based big data platform that enables customers to run analytics and machine learning applications. I use AWS Services, Java, Scala to develop, test, and deploy features and enhancements for the EMR console and API, ensuring high quality and performance. I also collaborate with other engineers, product managers, and customers to understand their needs and deliver solutions that meet or exceed their expectations.I have a strong background in computer science, with a Master of Science degree from Stony Brook University and a Bachelor of Engineering degree from University of Mumbai. During my studies, I developed a fully functional 3D educational game for students to learn history of India in a fun way, which was published in an international journal. I also gained valuable industry experience as a software engineer and senior analyst at Capgemini, where I handled dot Net applications, automated manual tasks using Python and UI Path, and improved the payment system for a client project. I am passionate about creating innovative and impactful software products that solve real-world problems and benefit users and organizations.
