• Qubole is a cloud-native data management platform for analytics and machine learning that allows enterprises to quickly harness the power of data to gain valuable business insights.
• I have contributed to 2 major projects at Qubole - Package Management and Zeppelin Notebooks.
• Package Management helps the data-scientists to add, remove, and update Python and R libraries to multi-node clusters.
• I have worked as one of the core contributors to this project and played a critical role in developing it.
• I have end-to-end built the Activity History feature that defines a timeline of the packages modified in a particular environment. It also provides the option to restore the environment to any previous state if the current state gets corrupted.
• I have also added the support for viewing the live package installation logs which are streamed from the cluster for transparency and debugging purposes.
• I revamped the complete UI of Package Management to make it more user friendly and accommodate new features.
• Furthermore, I dockerized this application to make it work along with a Jupyter Notebooks container using sidecar pattern in a Kubernetes pod.
• Zeppelin notebooks enable data-driven, interactive data analytics and collaborative documents using Python, R, Scala, SQL, and other languages which communicate with interpreters like Apache Spark using Apache Thrift.
• I implemented a long-requested functionality of executing an external notebook, residing on another cluster, in the context of the caller notebook, this helped customers to define common utilities and libraries in a single notebook and include it in the caller notebooks. The introduced functions supported recursive calls while handling cycle detection.
• I have added various features and fixed numerous bugs to make Zeppelin notebooks robust.
• Technologies Used: Java, Shell Scripting, Ruby on Rails, ReactJS, Redux, MySQL, AWS, GCP, Kubernetes, Docker

• Events High is an events-marketplace startup that provides a platform for the users to discover events around them and a self-serve solution for the event organizers for end-to-end event setup and management.
• Key Responsibilities:
• I have built and owned the "Organizer Dashboard" which was one stop solution for the event organizers to manage event listings, set up ticketing, collect payments and see the real-time report on how event sales are going on. This was developed on AngularJs framework with firebase DB as backend. I was the developer of this project and have written the code single- handedly. This system has 20000+ signed in users and was managing the sales and payments records in few crores per month for these organizers.
• I was also handling the checkout experience on the Events High website where the users can book tickets for the upcoming events. The ticketing solution was customized to support custom registration form -- e.g. running event would ask for the blood group before registration and would need details per participant while a theatre event can be booked in a group without additional details. This system has served 1 order per second at peak times. Apart from user-facing checkout flow, this system was also managing the payments to organizer and reporting for organizers.
• I have integrated this system to various payment gateways like RazorPay, AmazonPay, PayTM and PayuMoney and have integrated with the cashfeee system for organizer payouts.
• I have also built the internal support system for the support team to see the pending transactions, issue tickets or see organizer records.
• I have worked closely with the co-founders of the company in planning and execution of the monthly goals.
• Technologies Used:
• Google Cloud Platform (App Engine, Compute Engine, Datastore, and Cloud Endpoints), Java, Firebase, AngularJs, Maven, Gulp, and Nodejs.
