Java & Spring Boot Architect | AI-Powered Backend Systems | 14+ Years Experience I am a Java & Spring Boot architect with 14+ years of hands-on experience building production-grade enterprise systems — from core banking platforms to AI-integrated microservices. I hold a BSc in Computer Science & Technology and now work as a dedicated full-time freelancer on Upwork, bringing the same rigour I applied in large fintech institutions directly to client projects. My core expertise spans Spring Boot, Spring Framework, and microservices architecture, with deep practical knowledge of SSO & Keycloak, Docker, DevOps pipelines, and GitLab CI/CD. I design systems that are secure, observable, and built to scale — whether that means integrating Kafka for event-driven flows, Flowable BPMN for workflow automation, or AWS for cloud infrastructure. Over the past year I have been heavily invested in the AI/LLM frontier: building Spring AI applications, wiring up MCP (Model Context Protocol) servers, running local models via Ollama, and implementing advanced patterns like tool calling, RAG pipelines, and AI agent workflows. I see AI not as a separate layer but as a first-class citizen inside enterprise Java backends. If you need someone who understands both the old-school reliability of enterprise Java and the new possibilities of AI-augmented architecture — let's talk.
