• Worked on developing a system of monitoring for Cisco’s next gen Connected Supply Chain. Using Python with Flask to build backend and AngularJS for frontend web-based UI. This monitoring system includes alerting mechanisms for system and application stats, graphing system for system and application stats and log search functionality using Elastic-search as backend.
• Worked on developing a continuous integration and deployment system used for development, testing and shipping the software of Connected Supply Chain. Used Python on Flask for backend and AngularJS for frontend web-based UI. Many open source technologies are glued together in this project to create the entire CI/CD system. These open source technologies include Jenkins, Pulp, Celery, Ansible and Gerrit. A major chunk of work in this project was on gathering and distilling the requirements since customers were themselves not sure of what kind of CI/CD system they wanted. This lack of clarity required building and scrapping a lot of prototypes to elicit the requirements from customers.
• Developed REST APIs for business requirements of Supply Chain. This helped me in understanding the various business processes involved in Supply Chain.
