• Worked on the media service to streamline the uploading and manipulation of media files across various cloud platforms, such as AWS, Azure, and GCP, by integrating these cloud services. • Engineered a robust microservice for managing catalog data, streamlining product addition, tagging, and categorization; expedited bulk uploads via CSV files, reducing catalog management time by 40% for product teams. • Designed a Dockerfile for the cron functionality, ensuring smooth containerization of the task. Integrated this Dockerfile into the CI/CD pipeline to automate the deployment process, enhancing efficiency and reliability in managing cron jobs. • Work on the logistics service to make the delivery process smooth, cost-efficient, and easy to use, like integrating with SHIPROCKET and DUNZO API.

• Implemented a seamless migration of a critical microservice, transitioning it from its original framework to a more optimized framework. This migration specifically focused on enhancing the functionality and performance of the service responsible for uploading media files to both Google Cloud Platform (GCP) and Azure environments. • Developed a robust feature enabling the generation of signed URLs for images uploaded to Google Cloud Platform (GCP) and Azure. These signed URLs have a limited validity period, enhancing security measures and ensuring controlled access to the uploaded images.

• As a QA intern, I wrote test scenarios for a feature and manually tested them in Postman, adding assertions for validation. I then automated the tests in Postman. • Furthermore, I contributed to the automation process by writing scripts using our organization’s framework. These scripts automated the testing procedures, enhancing efficiency and reliability across the testing pipeline.
