• Ideated, architected, managed (a distributed team) and built a product based on Hyper Converged scale-out architecture for Data Virtualization with a hyper-converged exploration engine on top.
• There is huge value in building Hyper-Converged Data Infrastructure (HCDI) as an extension of Hyper-Converged Infrastructure (HCI). Beside being able to program the infrastructure, it also brings the ability to program the data of the whole enterprise. In other words, it virtualizes the data of the whole enterprise. #datainfrastructure, #hci, #virtualization, #hcdi

• Technologist & Product Architect of Cloud Managed Services platform. Responsibility was to create a highly scalable managed services platform that has significantly lower operating cost, component level independent scalability, auto resolution of critical issues, contextual guide to the support engineers to solve issues, auto-immunity, high degree of fault tolerance, rapid development cycle, significantly lower time to market, significantly lower cost of development, significantly lower cost of ownership (all open-source), and highly reduced number of human resources.
• The above mentioned niceties are possible due to very advanced development strategies-methodology and super advanced set of technologies. The technologies worth noting here are - Scala, Akka, NodeJS, ElasticSearch, AMQP, etc.

• Built a product called Phalanx within remote management systems. It involved a mix of realtime network monitoring, automation, and reporting and analytics. Designed to report device issues, solve them automatically, generate tickets if not resolved automatically, and produce reports and analytics. It monitored large, diverse networks and the devices and software in the networks; namely for fault, performance, and security. It involved realtime processing of some information and large volume processing of others.
• Lauded as a very unique framework that was flexibly distributable, application-server-less (except the visualization part), and extremely high-performing. Akka with Scala was used extensively to make this magic possible with NodeJS as the interface to the external world.
