## About

Technical Architect with 12\+ years of experience designing and delivering scalable, high\-performance fintech and digital banking platforms\. I specialize in Java\-based microservices, cloud\-native architecture, Active\-Active high availability models, and performance\-critical systems operating at scale \(1000\+ RPS / TPS\)\. Over the years, I have led architecture and delivery for wallet platforms, charging systems, and digital banking products, modernizing legacy platforms into containerized, cloud\-ready solutions using Kubernetes and Azure AKS\. Currently, I am architecting a digital banking platform and driving Oracle\-to\-Java modernization initiatives, leveraging AI\-assisted prompt engineering to accelerate delivery while ensuring functional parity, performance stability, and regulatory compliance\. I have hands\-on experience leading engineering teams, working directly with global clients, and delivering systems from architecture design through UAT and production go\-live\. My career focus is to grow into Principal Architect and technology leadership roles in fintech and digital banking\.
