About

I am passionate towards solving challenging problems. I like working on distributed systems and writing a lot of code. I believe that versatility is one of the most important skills an engineer can have. I’ve got exposure to consumer centric teams working on data mining and machine learning at Microsoft Bing, as well as low level data path in data centre applications with the Rubrik converged data management appliance and control+orchestration flows on the cloud in a multitenant environment with Rubrik Security Cloud. Tech: C, C++, Python, Java, C#, GoLang, Scala, gRPC, Protobuf, GraphQL, Kubernetes, Service Fabric.
