SAP HANA Virtualization and Big Data • Successfully grew to 1000+ customers • Built native integration of virtualization engine in HANA to run analytics using HANA as the engine federating to multiple remote sources • Google BigQuery, Oracle, SQL Server, PostgreSQL, MySQL, Hadoop and other remote source supported • Advanced features include capability driven framework, cost-based query optimization minimizing data transfer • Query optimization, execution, and generation tailored for each remote source • Extend on-premise data to the cloud and tooling to support such extensions • Support relational and non-relational data like spatial, document store • Seamless integration with Hadoop for Big Data storage and processing • Data aging supported using Hadoop as a cold store for SAP Data Lifecycle Manager SAP HANA Streaming SAP HANA Smart Data Streaming is a streaming engine that enables you to collect, process, and analyze events from streaming sources in real. It has an integrated SQL like programming model • Built a lite version of the engine to be deployed on remote gateway devices for IoT use cases. It was built as a self-contained, independent server to be able to gather, filter, aggregate data on the edge • Enhanced the streaming engine incorporate machine learning algorithms to learn and make predictions based on incoming data. This included both supervised and unsupervised algorithms. • Developed a new REST based gateway for publishing and subscribing to the service. This new service had 1000 times better performance than the legacy service it replaced. • Integrated the product into SAP's cloud environment to offer Streaming as a cloud service • Developed a Python SDK for application developers to connect to the streaming engine

Development Architect • Designed and developed a Storage management system for managing the storage and retrieval of large data objects • Built a database independent system for managing the data on magnetic and optical media • Designed, developed, tested kernel mode device drivers for storage devices for diverse operating systems including Solaris, HP-UX, IBM-AIX, DEC OSF • Designed an integrated all-in-one development platform, which maintained a single source code baseline across UNIX and Windows for Networking, job control, File system, Inter process communications, Multithreading, TCP/IP, WinSock etc. • Developed an automated file system based hierarchical storage management system. It delivers a rule based, tiered solution for migrating less frequently used data from higher cost storage to lower cost disk, tape, or optical devices.
