• Contributed as an architect to a cross-functional and geographically distributed team that implemented performance enhancements to scale the existing application, driving $1M+ in additional revenue. • Enhanced the network test result anaylsis product by implementing massive-scale (scaling from 64K streams to 10M flows) autonomous flow tracking feature along with real-time event correlation. • Feature evolution of a high-throughput historical time-series data engine along with production support. • Engineered a cross-platform log aggregation tool that ingests unstructured logs from distributed services across Windows, Linux, and Chassis nodes, transforming and streaming them as structured data to a centralized location. • Extracted business domain logic from monolithic system (C#, C++) and architected corresponding micro-services applications (Golang, Docker) for improved scalability and maintainability. • Pioneered Golang adoption in the India dev center as the first engineer to contribute to a US-led modernization initiative, paving the way for the broader team's successful transition to the modernized platform. • Worked on legacy full stack composing of C# UI, C++ middle-ware & Python hardware layer of the existing application to deliver a feature to obsolete legacy hardware within a few months of joining the organization. • Mentored junior engineer to get up to speed with the existing application architecture and code structure. Helped them to get going on bug fixing & feature development.
