// about me

About

I am a Senior Principal Software Engineer and Core Banking Domain Expert specializing in Islamic Banking systems. Over my career, I have engineered high-performance enterprise architectures, robust backend systems, and complex database ecosystems for critical financial infrastructure.

My technical expertise centers on building resilient microservices using Java and Spring Boot, paired with deep data layer engineering as a PL/SQL expert. Bridging the gap between development and mission-critical operations, I specialize in cloud-native DevOps practices, specifically orchestrating containerized production deployments using Docker Swarm and VMware Tanzu VCF Kubernetes clusters.

A definitive milestone of my career includes leading high-complexity core banking migrations, notably transitioning legacy architectures from Temenos T24 to AbabilNG, and successfully deploying AbabilNG into enterprise-grade Tanzu K8s environments. I bring a unique perspective to fintech innovation, combining rigorous database design, advanced API development, and secure infrastructure automation to deliver banking excellence.
