I'm a Senior Java and Spring Boot engineer with 3+ years in production roles and 5+ years delivering for international clients. I build secure REST APIs, event-driven microservices (Kafka, RabbitMQ), and multi-tenant SaaS backends that scale, plus AI capabilities (RAG, LangChain, OpenAI) when a product needs intelligence, not just CRUD. Recent work: migrating a monolith to multi-tenant microservices SaaS, and automating workflows with Camunda BPMN. 5.0 rated on Fiverr. Message me with your project details and I'll reply with an honest scope and timeline.
