About

A Backend Software Engineer with 2+ years of experience in designing, developing, and optimizing scalable, high-performance applications. At Games24x7, I work as a Java Backend Developer, specializing in Spring Boot, SQL/NoSQL databases, and microservice architectures. I have hands-on expertise in building reliable APIs, refactoring legacy services for performance improvements, and integrating third-party systems. My experience includes working with Kafka, Redis, and AWS (MSK, S3, EC2, Lambda) to build event-driven and cloud-native solutions. I’ve contributed to impactful projects such as payment service enhancements, wallet service refactoring, and the launch of new games (Ludo & Ludo Lite). I focus on writing clean, maintainable code, improving resilience with retry/error handling, and ensuring high availability in production systems. 🔹 Previous Experience: At Brane, I designed and deployed a predictive test analysis tool using Golang, Node.js, and MongoDB. Leveraging Redis for efficient data operations and adopting microservices, our team enhanced debugging processes and streamlined data retrieval—demonstrating my ability to innovate and collaborate effectively.
