Software Developer
Pampanga, Angeles, Philippines
I am a software engineer with over 18 years of experience in designing, developing, and maintaining backend systems across a variety of industries. My primary expertise is in Java-based backend development, with strong experience using frameworks such as Spring and Spring Boot to build reliable and scalable applications. Throughout my career, I have worked extensively with relational databases including PostgreSQL, MySQL, and SQLite, focusing on transactional integrity, performance optimization, and maintainable data architectures. My experience spans enterprise environments, outsourced development teams, and remote collaborations with international clients. I have contributed to the design and implementation of production-grade systems, RESTful APIs, and backend services that support real-world business operations. I place strong emphasis on clean architecture, well-structured code, and long-term maintainability of systems. In addition to backend development, I have experience with Linux-based environments and cloud infrastructure such as AWS and Azure, including server setup, deployment, and system configuration. I am comfortable working with version control systems like Git and collaborating with cross-functional teams to deliver reliable software solutions. Earlier in my career, I also served in technical leadership roles where I guided development teams, performed code reviews, and contributed to architectural and technical decision-making. These experiences strengthened my ability to balance technical depth with practical delivery in real-world projects. I enjoy solving complex technical problems, improving system performance, and building software that is stable, scalable, and reliable. My focus remains on backend engineering, particularly in environments that value structured development practices, system reliability, and thoughtful software design.
