* Worked with Data Platform team in prototyping the team’s next generation architecture by designing and implementing IoT Thing registration using AWS services such as SNS, SQS, Lambda and IoT Core saving the cost by 10% which incurred with the Just In-Time Provisioning Solution.* Authenticated vehicle with X509 certificates and used MQTT protocol to enable bidirectional communication between the vehicle and the cloud which improved the average response time from 300ms to 50ms.* Created API GW, DynamoDB, Redis Cache and Integrated it with the Lambda to send down remote commands from the cloud to the vehicle. Ex: UNLOCK_ALL_CLOSURES

Us

* Designed and Implemented Search Services using Java+Springboot which used Azure Cognitive Search and Azure Cosmos Database as a data source with a response time of under 150ms.* Developed persistence layers for 14 OptumRx domains using Java+Springboot consuming data from Kafka that pushed data to Azure CosmosDB in real-time and moved more than 4B records from on-prem to the cloud in production.* Devised a validation framework that processes validation of 3.5K documents/sec using Apache Spark in Databricks to validate the data at the Azure Cosmos database against the data in Kafka.* Improved the time-to-build by 15 % by setting up CI/CD pipelines using Jenkins which build Docker Images and pushes to Azure Container Registry which is then launched by Azure Kubernetes Service(AKS).* Mentored junior engineers to onboard them to the team. Helped them understand the project's architecture and resolved any technical issues along the way.

Worked under the guidance of Prof. Virendra Singh as an intern :* Build a model trained on CIFAR-10 dataset having 60,000 images using CNN to find similar images corresponding to queried image. * Extracted feature by employing 7 convolution layers followed by max-pooling and then applying Rectified Linear Unit(ReLu) as an activation function.* Harnessed CrossEntropyLoss as the criterion for the backward propagation with Adam as the optimizer which resulted in 88% accuracy on the test data.
