Tax Testing Platform TeamPlatform team that enables targeted regression and load testing for clients with millions of test case generated from production traffic.• Designed and implemented the core replay functionality to replay production traffic against gamma stacks. Built a generic dispatcher to call a service endpoint and custom interceptors to extract replaycontext used to stub non-deterministic behavior in code. Platform generates and executes 250M+ tests each month.• Worked on the high-level and low-level design for comparator service during re-architecture and migration to on-demand compute to solve noisy neighbor problem.• Implemented a solution to compare actual vs expected for list structures with non-deterministic ordering with infinite nesting.

CoBranded Credit Cards (CBCC) TeamCBCC team worked on launch of co-branded cards in new marketplaces in EU region and provide a smooth customer experience as part of application process and credit card servicing.• Worked on the design of card application workflows and implementation and testing of credit card upgrades in UK marketplace. More than 30,000 customers upgraded following this workflow• Built a notification system to send emails to customers on changing preferences for credit cards through Amazon• Built a new 'Existing Card Members' page on an Amazon proprietary platform called Horizonte. This was a one stop page for serving customer needs like checking reward points and changing customer preference related to the card• Built an event-based workflow to call a bank API for each credit card transaction on Amazon to pass transaction metadata like offers applied, bypassing issuer networks like Visa and Mastercard.

TEAM- DECISION SCIENCE PLATFORM DSP team is responsible for creating and maintaining a forecasting platform that can run statistical and machine learning algorithms written in 'R' and 'Python' to run at scale while providing certain guarantees like data completeness, consistence etc. 1) Worked on the HLD with guidance and did LLD for workflow orchestrator. 2) Implemented a generic Metric Compute workflow to execute statistical models with an execution engine interfacing between Java and R. 3) Working on building a deviation/rca platform on top of DSP to find the root cause of the deviation between plan and actuals to provide actionable items to improve forecast accuracy for future. TEAM- INTEGRATED PLANNING PLATFORM IPP team is responsible for creating planning platform, a single destination to meet the needs of all business teams doing Demand planning, Supply planning and Inventory Planning. 1) Built a platform to power input driven planning across all of Flipkart. 2) Built the capability to generate plans in near real time by updating inputs and be able to view and analyze the plan/data across different granularities. 3) Capability to measure the same fact across different hierarchy trees and changing granularities. Also built the capability to provide audit trail for facts with changing planned numbers during the planning cycle. 4) System capability to view and compare Demand Plan vs Actuals data along any product hierarchy.

TEAM- DEMAND FORECASTING PLATFORM 1) Built a configurable platform to onboard statistical forecasting models written in 'R' to generate demand forecast used in downstream system. 2) Various data pipelines to gather the historical data required for the forecasting models.

Team: Multicast SnoopingI was responsible was creating a test suite of smoke tests to check the multicast snooping functionality and make sure that multicast features provided by Juniper to client did not fail.- Learned the concepts of router and bridge configuration.- Implemented tests in Juniper Code Markup Language for all possible router configurations.

Worked with the Reactor Physics department at Tarapur Atomic Power Station 3 and 4.- Developed a program in C for processing the 'Delayed Neutron Count' data produced by the nuclear reactor and checking for any abnormalities.- The output was written in an excel sheet to be viewed in graphical format later on for better clarity.- Conducted a small training program to teach the use of the tool to employees in the reactor physics department.
