Philippines
I am a Senior Java / Backend Developer with 9+ years of professional experience building scalable, secure, and high-performance enterprise systems for finance, insurance, logistics, and government platforms. I specialize in Java 8–21, Spring Boot, RESTful & GraphQL APIs, microservices architecture, and cloud-native solutions. I’ve worked on mission-critical systems used by large organizations, including insurance portals, loan platforms, customs clearance systems, and government applications. I don’t just write code — I solve business problems, improve system reliability, and deliver maintainable solutions that scale.
