During my tenure at SAP, I majorly focused on development of SAP Vora, a low latency In-memory distributed compute engine designed for realtime analytics of data on Hadoop. Following are some of my contributions to the product.

• Engineered a high-performance concurrent hash map in C++ utilizing the hopscotch algorithm, surpassing the performance of open-source implementations.

• Optimized the SAP Vora in-memory engine by replacing mutex-based locks with a concurrent hash map, resulting in a 20% increase in system throughput. Achieved a similar throughput improvement within the network stack.

• Developed a low-overhead, high-performance metric reporting client for SAP Vora, employing macros to minimize client footprint and invocation overhead.

• Contributed to the development and rigorous testing of an in-house monitoring and alerting system, ensuring system reliability and stability.

As an intern at Altice NYC, I contributed to the company's shift towards stream-based set-top boxes by creating a proof-of-concept Android TV application that successfully demonstrated the streaming of DRM-protected content.

• Developed a standalone Android TV application enabling cloud-based streaming of protected content, incorporating comprehensive video playback controls and a robust catalog search functionality.

• Contributed to development of Network management suite for managing hardware.

• Developed APIs for network commissioning, management and performance monitoring.

• Developed tools for data collection from network equipment and analyzing.

• Worked with many telecom giants across globe. Helped network engineers in using the product and troubleshooting their network.

• Wrote network drivers for Hughes Point to Multipoint hardware.

• Added support for Quality Of Service (QoS) for prioritizing network data in Point to Multipoint networks.

• Automated the process of testing hardware failures.

• Added several enhancements and resolved bugs in the embedded software. This equipment is used by many telecom giants in the world.
