- Leading the efforts on the editors-architecture (cloud IDE), collaboration solutions for data-science and scaling our cloud assessments platform. - Reduced cloud infrastructure cost by ~55% for Developer Skills Platform through cluster changes - Document and plan tasks and action-items with stake-holders (product and engineering team) - Monitoring and dashboard setup for usage and analytics for Skills platform and Cloud assessments - Improved the scale for cloud engineering role by 500%

- Document, design and implement the ingestion pipeline for data generated from the various data sources of HackerRank for Enterprise and HackerRank for community. - Wrote spark jobs for data processing pipelines to support use-cases like Skill Rating, Benchmarking and Developer Skill Profile. - The system currently ingests data from more than 60 million submissions every year and provides insights in near real-time being the underlying module for all skills based information presented across the products. - Logging, alerts and dashboard for monitoring of the data getting ingested and processed. - Optimised spark jobs to generate computational results from 24 hours to ~2 minutes for candidate packet data. - Unit test and travis setup for the computational spark jobs using pytest and travis - Eclipse Theia CDN integration and extensions to customise it. Reduced the load time for the IDE by ~50%.

- Integration of cloud IDE for frontend, backend, frontend, data-science assessment in HackerRank for work platform - Unit-testing and best practices setup for the backend - Wrote extensible backend service used for workspaces lifecycle - Build new features and fix bugs
