About

I’m a Backend Software Engineer with 3+ years of experience in designing and building scalable, resilient systems that solve real-world problems at scale. My expertise spans Java, Spring Boot, Microservices, Kafka, AWS, C++, and MySQL, with a strong focus on architecting systems that are reliable, adaptable, and built to last. What drives me is the thrill of problem-solving — turning complex challenges into simple, effective solutions. Whether it’s debugging critical production issues or architecting distributed systems, I love tackling puzzles that push me to think deeper and deliver better. Beyond the technical side, I’m a team player and lifelong learner, passionate about continuous improvement, knowledge-sharing, and applying technology to create meaningful impact. Currently, I’m part of Walmart Global Tech, contributing to systems that touch millions of customers every day. Always open to connecting with fellow engineers, innovators, and problem-solvers 🚀

In my role as a Software Engineer at Chai Point, I've demonstrated expertise in designing and implementing robust solutions. Notably, I spearheaded the creation of a highly scalable, fault-tolerant event-based architecture, achieving significant improvements in real-time event processing and a 99.9% reliability rate using AWS EventBridge, SQS, Lambda, and SES for seamless order-event transmission to MoEngage. Additionally, I designed and optimized an AWS data streaming pipeline for efficient real-time data processing, integrating AWS Gateways, Kinesis, S3 bucket, and Athena. My contributions extended to integrating Zomato with Chai Point through Spring Boot-based microservices, resulting in a notable 20% increase in profitability for Zomato orders. I also played a key role in enhancing data security and maintainability by developing a Java application with Spring Boot and MySQL for API credential management. Furthermore, I optimized database space utilization by 98%, introduced batch processing for improved database availability with a 70% faster execution rate, and achieved a 95% faster data retrieval from the database through code optimization using Java 8 Stream-API and database indexing.
