About

I’m a backend engineer with 4+ years of experience building scalable, high-performance systems and AI-native platforms. At Verizon, I designed and optimized RAG pipelines and real-time conversational bots using Golang, WebSockets, and AWS services (Lambda, API Gateway, Cognito, S3, DynamoDB, Bedrock). These systems reduced AI inference latency, improved throughput, and enhanced deployment agility. Previously, as a Member of Technical Staff at VMware (Broadcom), I worked on Tanzu Service Mesh, contributing to core platform capabilities including secure service discovery, intelligent routing, and performance optimization using Golang and cloud-native tools. Earlier in my career at ZopSmart, I developed and maintained multiple microservices for the retail platform—integrating third-party logistics APIs, streamlining delivery operations, and building RESTful APIs in Golang. Beyond industry roles, I’m passionate about mentoring and giving back. At PrepBytes, I helped students strengthen their understanding of Data Structures and Algorithms, guiding them through complex DSA problems. I hold a Master’s in Computer Applications from NIT Jamshedpur and a Bachelor’s in Computer Science from Patna Science College. I'm driven by curiosity, continuous learning, and a mission to solve real-world problems through clean architecture and smart automation.
