- Working on experimentation platform to improve experiment velocity and experiment bandwith for ads within app store

Cupertino, California, United States

- Architected app blacklisting flow by optimizing scanning logic with caching, thus expanding system’s coverage for over 50 countries, significantly reducing the processing time by 97% (from a week to 4 hours)- Redesigned the entire microservices backend, using change capture and streaming, resulting in a 10x reduction in messages and resolving synchronization issues for advertisers- Engineered a high-performance index-building pipeline by integrating advertiser campaigns with algorithmic scores, and enabled up to 50 index-based experiments- Designed an inference engine to enable prediction improvements by supporting tree models within Ad Serving stack

Cupertino

Built a stats framework to provide visibility and monitor index building pipelines, which was adopted by SRE for ongoing use.Developed and managed backend services for the ad server, processing millions of daily requests and integrating machine learning models

Urbana-Champaign, Illinois Area

- Built a database-exploration based test framework to generate over 25,000 cases to extensively verify the security model of java beans.- Developed and deployed ‘sparse field-sets’ end-to-end feature in Java and JavaScript for web service platforms, thereby reducing the query response times by over 20 percent. - Created a data schema and updated the database and web service to integrate 4 new partners into the mobile data analytics platform.

Greater Boston Area

- Developed a demodulation back-end profiling script using Python and identified a 5 percent sub-frame loading time between the busy and idle slots. - Implemented a non-linear interference cancellation algorithm C++ and Vector Processor DSP for low cost wireless modems using 6 percent of the cycle time to boost the output signal strength by up to 6 dBm.

Bangalore

- Designed and implemented a record and playback prototype using Java and Selenium, reducing the defect filing time by 20 percent.- Developed an automation tool using Java with on the fly object recognition and a simple tokenized language, leading to a 2x increase in the automation productivity.- Led the code coverage and quality initiatives across Cisco Services by working across cods-functional teams with presentations and demos, and thereby increasing the coverage rates by 30 percent.

- Developed an algorithm in Java and discovered the routers and the links between them using the SNMP entries of OSPF routing protocol for real-time network monitoring and failure analysis.
