About Me
I’m a results-driven software engineer with 7+ years of experience in building scalable, reliable backend systems and middleware. I specialize in RESTful microservices using Java, Spring Boot, and Apache Camel, and have deep expertise with messaging systems like Apache Pulsar and Kafka.
At Narvar, I architected systems that processed over 10 million daily transactions and drastically cut integration timelines. I thrive in solving complex business problems with elegant technical solutions, leveraging solid OOP principles, design patterns, and modern DevOps practices.
Now on a freelance journey, I help clients deliver robust backend systems, custom integrations, and scalable APIs tailored to their product and platform needs.
