Leading Video infrastructure and Product engineering at hotstar. Team is focussed on building an awesome customer experience for the largest video consumption channel in India. With hot properties like IPL, Game of Thrones and now hotstar specials we are on a mission to redefine the content consumption story.

Working on a mission to make Facebook Live more interactive with features like bringing a guest into your live session.

Delivered a messenger platform to target the social network of businesses and their loyal customers. - Mobile backend on AWS. - Mobile app on iOS and Android.- M-commerce marketplace for businesses to enable shopping inside the messenger.- Content feeds inside the messenger to enable content rich conversations.- Led a multidisciplinary team of server engineers, iOS, android and UX designers spread across the world.

Led a team of server engineers and devops to deliver a real time internet acceleration service handling traffic up to 200Gbps - The service reduced video size by 50% and image by 70% with no quality difference.- Designed an out of path client side load balancing solution which became the key piece for horizontal scaling and deployment in hybrid cloud environment.- Vertically scale the system to handle up to 32 parallel real-time video transcoding sessions (480p and 360p) on cc2.8xlarge aws instance.- Built a highly scalable and stateless HMAC based authentication service.

· Worked extensively on static timing analysis tool (encounter timing engine), wherein the engine attempts to statically (without simulation) verify the synchronization of clock and data signals for every flop in the design. This is important for the correct functioning of sequential logic designs. Major challenge in this product was increased complexity of chips and multi million gate SOC’s. These complexities demanded that the existing algorithms were enhanced to take care of new features required as well as improve on the execution efficiency.· Developed and maintained algorithm for clock path timing calculation with various design constraints from sdc files.· Worked on clock latency calculation performance improvements. The execution time was improved over 50% in 2 monthsDesigned and maintained timing model extraction module. Extended timing model extraction module to produce accurate timing models for path based timing analysis.

Worked on a Fingerprint Identification system for chipcard and security business unit, wherein a smart card could be authenticated using fingerprint identification. The smart card had to be made capable of capturing a fingerprint image and matching with the stored fingerprint on the smart card, thus avoiding any central storage of fingerprint data. Contributed towards optimization of fingerprint encoding with respect to program size and efficiency. The whole fingerprint identification system was restructured / ported from C++ to C and then ported onto a dual core embedded test chip (Unispeech) consisting of 8051 Micro controller and Oak DSP.Developed a C library which was used to replace the STL containers like linked list, doubly linked list, queue , stack and map.Designed a novel algorithm to perform fingerprint encoding on overlapping strips of fingerprint image. This was initially done so as to optimize on internal memory. Later the same algorithm was used for stripe fingerprint sensors.
