As a seasoned Back-End Developer with a passion for data and scalable systems, I excel in creating robust, efficient solutions that drive significant impact. At Medable, I automated clinical trial workflows, reducing study launch time from 6 months to a week and boosting profit margins from -90% to +40%. At HackerRank, I led the design of a next-gen IDE, slashing workspace costs by 60% and enhancing concurrency by 10x. My expertise spans Golang, Python, PySpark, AWS, and more, consistently delivering high-performance, cost-effective systems. Leading teams and collaborating globally, I thrive on turning complex challenges into streamlined, scalable solutions.
