At Galaxy FinX Join Stock Company, I integrated card services with the Way4 Card System and Vault Core Banking System to support secure payment processing, real-time posting, and account updates.
I initiated a proof of concept and delivered a standardized retryable Kafka framework to handle back-office service failures and prevent cascading failures in card onboarding workflows. I also mentored three backend engineers through code reviews and technical discussions.
At Doxa Holdings International Pte Ltd., I designed and delivered the cloud-native microservices architecture for Doxa Connex, with a reported 30% improvement in overall functionality. I also delivered a H2H bank integration platform for secure, real-time data exchange with partner banks.
