- Drove extreme performance and security optimization by architecting a high-performance Java-based on-heap cache for DynamoDB authorization policies, which processes over 250 million requests per second, achieving a 99.4% cache hit ratio, and enabling a 7-microsecond P50 latency for the critical Consistent Authentication feature. - Owned and executed critical infrastructure projects including the complete migration of the DAX SDK for Go (v1 to v2) and the expansion of the DAX service to new AWS regions, validating resilience through rigorous gameday testing. - Drove the implementation of a zero-SSH access security policy for DAX server nodes, significantly improving system security posture and reducing Mean Time To Mitigation (MTTM). - Designed and developed scalable observability infrastructure by creating HealthMetrics for aurora, a centralized, multi-region health data platform supporting SLA reporting, customer issue analysis, and revenue-impact decisions across the entire AWS database services suite. - Reduced data staleness in core operational tools from 5-20 minutes down to 2-60 seconds (over 95% reduction), enabling near real-time metadata access and config-driven deployments.

Worked on developing a cloud library, for the transfer of any type of data to and from cloud providers such as AWS S3, Azure, GCP. The library is equipped to ensure transfer of TBs of data and hundreds of simultaneous requests. The library takes one tenth of the time usually taken with the use of threadpool model. The library is currently being used by various cross-functional teams under the Dell umbrella. Technologies used: S3 Rest APIs, Azure Blob APIs, BOOST library, Curl library Languages used: C++ Also, handled various high level customer RFEs and highly severe customer escalations.

Developed enterprise level backup protection software for Office365 Exchange data application from scratch. The solution consists of two decoupled layers with the REST server coded in NodeJS and the agent written in C++. Used the tree serialization format to store application agnostic data. Redirected restore of SQL database including UI changes using C#. Technologies used: Azure Graph APIs, curl library, socket programming, microservices Languages used: C++, NodeJS Concepts used: OOP, multithreading, JSON
