01. About Me

I'm a Senior Software Engineer at OpenText (R&D) with a passion for crafting high-performance, scalable backend systems. With over 6 years of experience, I specialize in Java, Spring Boot, Kafka, Microservices, and Distributed Systems across diverse domains including FinTech, Cloud Infrastructure, and Automotive Safety.

I have proven expertise in building scalable RESTful APIs, implementing event-driven architectures, and optimizing performance via caching strategies, code refactoring, and concurrency control. Proficient in cloud platforms like AWS (EC2, S3, Lambda, SQS) and Azure.

I graduated with a B.Tech in Electrical Engineering (Minor in CSE) from NIST University (National Institute of Science and Technology), Berhampur (2015–2019), where I was awarded Best B.Tech Project among 500 projects and served as President of the Robotic Club.
