What I'm looking for

I want to build scalable enterprise microservices and agentic Generative AI/RAG services using Java and Spring—working in Agile teams focused on quality, reliable APIs, and measurable business impact.

I’m a Senior Java Developer with 4+ years of overall IT experience across enterprise Java development, AI-powered application development, and QA. I build scalable applications with Java (8/11/17), Spring Boot, Hibernate, and REST APIs, with a strong focus on maintainable code, debugging, and unit testing using JUnit.

I’m especially passionate about building Generative AI and Retrieval-Augmented Generation (RAG) solutions for enterprise applications. I’ve delivered agentic AI-based services integrated with ENOVIA/3DEXPERIENCE, implemented LLM-powered assistants using Spring AI and OpenAI GPT-4, and designed RAG-ready architectures using pgvector semantic similarity search. I’ve also built an AI helpdesk service platform using Ollama with streaming and conversation memory, plus AI-powered analytics agents integrated into security dashboards, alongside automation and migration utilities using Java and shell scripting.
