Experience

1. Associate Software Engineer

   Amdocs

   Aug 2023 — Present · Gurugram, IN

   At Amdocs, I worked as a Software Engineer on large-scale telecom projects for BT and A1 Austria, where I focused on backend development, microservices, and database optimization.I designed and built REST APIs in Java and Spring Boot, migrated parts of the system from monolithic to microservices, and optimized Oracle SQL queries to cut down response times. I was also involved in system design discussions, writing clean, testable code, and ensuring smooth deployments in an Agile Scrum environment.For EEBT, I contributed to a service management platform that handled over 100K+ daily requests, building microservices for real-time monitoring and fault management. For A1 Austria, I worked on customer-facing features like onboarding and billing, where I reduced API response time from 2 seconds to under 500ms through caching and query tuning.Across both projects, I helped improve system scalability, reduced production issues, and ensured zero-downtime deployments, directly enhancing customer experience and reliability.This role gave me hands-on expertise in Java, Spring Boot, Microservices, REST APIs, SQL, and System Design, along with practical experience working with global teams to deliver enterprise-grade solutions.
