About

I am a Backend Software Engineer 2 at Walmart Global Tech, building high-traffic, concurrent backend systems within the Transactions and Payments platform. As an IIT (ISM) Dhanbad Computer Science alumnus and an active competitive programmer, I thrive at the intersection of algorithmic rigor and production-grade software architecture. In my day-to-day, I tackle complex distributed systems challenges—from architecting custom thread-pool utilities that eliminate deadlocks under massive TPM stress, to driving state-specific payment eligibility architectures. I specialize in designing fault-tolerant, low-latency microservices using Java, Spring Boot, and Kafka, ensuring absolute reliability for critical payment flows. Outside of production deployments, I am deeply passionate about competitive programming and algorithmic problem-solving. 🛠️ Core Tech Stack & Competencies: Backend & Architecture: Java, Spring Boot, Microservices, REST APIs, Concurrency, Multithreading, Distributed Systems Data & Messaging: Kafka, Redis, MongoDB, MariaDB, SQL DevOps & Observability: Docker, Kubernetes, CI/CD, Splunk, Grafana, JMeter 🎯 Competitive Programming Achievements: LeetCode Knight (Max Rating 2076) CodeForces Expert (Max Rating 1664) CodeChef 5-Star (Max Rating 2021) Meta Hacker Cup: All India Rank (AIR) 310 I am always open to connecting with folks discussing backend engineering, system design, and competitive programming.
