• Platformized payment gateway code to streamline integration with external payment processors. (C++)• Worked on friction/frictionless authentication support for 3DS transactions. (C++, Hack, Python)• Designed and implemented db logging support for the external platformization. (C++)• Enhanced sparse ads ranking models which increased ads clicks by 1% on Messenger surface. (Python)• Improved Feed/Search ranking models driving 0.27% growth in valuable business threads forMessenger. (Python)

Feed and Stories Machine Learning Infra• Redesigned logging framework to filter data from newsfeed and reduce write traffic by 75%. (PHP, Hack)• Created a storage tier for feed data relevant for recommendation, and improved retention to months (C++, Python)• Implemented asynchronous node based clients to access feed data, and support to handle 25% more read traffic.• Devised data recovery using Chronos job, creates periodic snapshots through Spark Pipeline. (HIVE, Dataswarm)

• Implemented a backup/restore utility to capture the workload configurations from WCP and Kubernetes, and package them into Helm charts. Streamlines installation, migration and versioning of workloads across vSphere clusters. (Kubernetes, Helm, Python).• Explored different Helm configurations and Helm integration with WCP. Configured Audit Logging for WCP and tracked Tiller performance for complex applications with Kubernetes API metrics.• Enhanced vAPI bindings to accept login banner while enabling WCP(Kubernetes) on cluster. Upgraded corresponding Postgres models and implemented a REST path for getting login banner from an authentication service on Kubernetes.

• Designed and created a multi-tier model for pooling of Oracle Connections for multi-threaded scenarios based on session and database settings. (C++, Oracle 12C)• Implemented Multilevel Tagging of database connections based on session settings and user defined tags. Wrote PL/SQL to provide callback support for scenarios when requested tagged connections are busy. (C++)• Synchronized session state between server processes residing on Database Resident Connection pools and connections maintained on client side pools of Data Provider. (C++, SQL)• Analyzed the Two Task Common protocol and upgraded it for efficient communication for synchronizing session state between the Database and Data Provider. Migrated the code to Oracle Cloud. (C, Oracle Call Interface)• Programmed to reduce latency involved with fulfilling connection requests by switching pooled connections across Pluggable Databases (PDB) and their services in Oracle Multitenant Architecture. (C++, OCI, Oracle12C)• Synchronized session states and NLS settings post migration across PDBs in a Container Database. (C++, XML)• Handled data requests initiated for a connection after a planned or unplanned Failover happens from a failing instance to a working instance of a database. (C++, OCI, PL/SQL)
