What I'm looking for

Seeking a challenging role in software development with opportunities for growth and innovation

I am a seasoned Java software engineer with a strong background in designing and developing scalable software applications. With a Bachelor in Computer Science from NED University of Engineering, I have honed my skills in Java, Spring Boot, Microservices and AWS cloud.

Throughout my career, I have worked on various projects, including the development of e-Invoice modules, migration of monolithic applications to microservices, and implementation of secure authentication and authorization mechanisms. My expertise in Java 17, Kafka and Docker has enabled me to optimize system performance, reduce potential vulnerabilities, and improve code quality.

I am passionate about staying up-to-date with the latest technologies and trends, and I have participated in various conferences and workshops, including DevOps Day Kuala Lumpur. I am committed to delivering high-quality software solutions and contributing to the growth and success of my organization.
