About Jayant Kumar
I am a Software Engineer with nearly 3 years of experience specializing in building scalable microservices and high-performance cloud applications. My expertise lies in Java, Spring Boot, and AWS, with a deep focus on architecting distributed systems that handle complex enterprise workflows. I thrive on solving intricate backend challenges, from designing RESTful APIs and event-driven architectures using AWS EventBridge and Kinesis, to optimizing database performance across SQL and NoSQL environments like MongoDB and DynamoDB. Beyond my professional role, I am a dedicated Competitive Programmer. I have solved over Data Structures and Algorithms (DSA) problems in Java and hold a 3-star rating on CodeChef. I am a frequent innovator in the hackathon circuit, recently recognized as a Regional Winner at the 2025 Amex GBT Hackathon, alongside four inter-college level wins.
