Freelance Enterprise Backend Programmer: Modernizing Java Spring/Hibernate & SQL Systems to Cloud

My 15+ year software engineering career began in mission-critical enterprise systems—building double-entry accounting applications with Java, Spring, Hibernate, and Oracle SQL before expanding into Python (Django/FastAPI), Go microservices, and AI application engineering. That deep foundation in strict relational ACID transactions, unit testing with Mockito, and enterprise domain modeling informs every system I architect today.
