I am a Java Full Stack Developer with hands-on experience designing, developing, and supporting enterprise-scale web applications in regulated financial environments. My backend focus centers on Java, Spring Boot, and microservices, and I strive to create scalable, maintainable workflows while delivering reliable API integrations and well-structured services. I enjoy building RESTful APIs, implementing service-layer business logic, and ensuring robust validation, error handling, and documentation. I work with database-backed applications using JPA/Hibernate, JDBC, and SQL, and I connect backend services with responsive frontends using modern JavaScript frameworks. I value clean code, CI/CD practices, containerization, and environment-specific configuration, along with secure development and compliance-minded practices. My cybersecurity training helps me contribute to secure coding and risk-aware development in fast-paced enterprise settings.
