At UnionBank of the Philippines, I build and maintain Java and Spring Boot microservices for banking systems, with Oracle SQL behind a Spring Cloud API gateway. I also integrate payment gateways, digital wallets, and card tokenization.
I write Bash scripts and internal tools to automate operational and back-office work, including database replication health checks. After diagnosing API gateway connection-pool exhaustion under heavy traffic, I tuned pool and timeout settings to improve reliability.
At HC Consumer Finance Philippines (Home Credit), I built the backend of a high-volume web application with role-based access control. I implemented RabbitMQ messaging with safeguards against message loss and duplicate processing.
At White Cloak Technologies Inc., I enhanced and supported fintech applications and HR systems, improved performance and security, and resolved findings from VAPT and QA testing. My work has also included API security, database optimization, and deploying releases to test and production.
