About

Backend engineer passionate about building high-performance systems, scalable data platforms, and clean service architectures. At Walmart, I architected real-time marketing pipelines with Kafka, modernized core services, and introduced AI-powered tools that accelerated development across teams. At ADP, I designed backend platforms that powered 90%+ of tax/payroll workflows—building reliable services for metadata caching, auth, and orchestration. At TCS, I automated Ericsson’s global license delivery, reducing turnaround from days to seconds, and optimized telecom asset management. I bring deep experience with distributed systems, microservices, Kafka, Spring Boot, PySpark, and cloud platforms like GCP. I thrive in fast-paced environments where backend engineering drives product impact at scale.

Worked on ADP’s Tax/Payroll Compliance products to enable validations and add new compliance mechanisms as per respective tax agencies and US tax laws(for ex : Covid Relief act), to provide seamless client experience.
Worked on Client On boarding orchestration platform for creating/updating/fetching client tax profiles and syncing said changes across required products. Almost 90% of the tax/payroll subscription was routed by this platform.
Worked on centralized metadata caching microservice (used in memory cache: springboot + EhCache) that minimized frequent DB calls and improved metadata call performance for caller apps by 60 to 80% (it’s been adopted by 10+ apps internally).
Worked on API Auth Gateway (using spring cloud gateway as base) for authorizing caller apps (using Oauth 2.0) and provided scope for corresponding product access.
Worked on Standalone microservice for invoking parallel bulk REST calls, which gave users the flexibility to delegate parallel call invocation to this component by passing multiple REST calls in a single payload and receive combined response (adopted by 3 apps internally).
