About

I am a Specialist Software Engineer with over 5 years of experience in architecting and scaling enterprise-level applications. Currently at AT&T, I focus on the Account & Billing Request (A&BR) ecosystem, where I design frameworks that handle complex order lifecycles and high-volume billing validations. My expertise lies in building robust back-end systems using Spring Microservices and ensuring they are secure, scalable, and data-driven. Core Technical Areas: Framework Design: Developed custom Rules Frameworks for dynamic validations and File Processing systems supporting delta/full loads. Security & Scalability: Expert in Spring Security (JWT/Basic Auth) and monitoring high-scale environments using Kibana, Grafana, and Prometheus. Engineering Excellence: Strong advocate for TDD, API design (Swagger/draw.io), and AWS infrastructure support. I hold a B.Tech in ECE from KIIT, Bhubaneswar (2020). I am passionate about solving intricate architectural challenges and mentoring the next generation of engineers to build better software.
