What I'm looking for

I seek roles building scalable, autonomous AI systems that combine enterprise Java architecture with LLM integrations, offering technical ownership, collaboration, and opportunities to drive production-grade agentic solutions.

I am a seasoned Java backend engineer with over nine years of experience building enterprise-grade systems and distributed microservices. I combine strong Java 17, Spring Boot, Hibernate, and database expertise with modern AI integration using LangChain, CrewAI, and RAG pipelines.

Currently I am developing an Agentic AI Proof of Concept that demonstrates the Reflex Paradigm for reflection-driven reasoning loops, multi-agent coordination, tool-calling, and adaptive task planning. I design pipelines for context memory, real-time decision feedback, and continuous agent improvement.

My professional background includes building high-throughput flight operations and order management microservices, batch and message-driven workflows, and API integrations for airline systems. I emphasize reliable code through unit testing (JUnit, Mockito), scalable caching and NoSQL integration, and production support for mission-critical systems.

I seek to apply my combined expertise in enterprise Java architecture and agentic AI to deliver scalable, autonomous, and high-performance applications that integrate LLM pipelines with Java and Python backends to solve complex operational problems.
