About
I'm a Senior Full Stack Engineer with 14 years of experience across Java-J2EE, full-stack development, data engineering, and cloud technologies. I currently work at Aplikasi Coda Sdn. Bhd. (Codapayments), and previously spent time at Insynchro Sdn. Bhd. in Malaysia and IBM India.
I specialize in designing and building scalable, high-performance systems — from real-time messaging and observability platforms on AWS, to microservices architectures, enterprise system integrations, and cloud-native infrastructure using Terraform and AWS CDK.
I'm also an active user of AI-assisted coding tools like Cursor, Kiro, and Claude to accelerate development and improve code quality.
