What I'm looking for

I'm looking for opportunities to build scalable Java backend and AI-powered applications, contribute to reliable REST APIs, and grow through hands-on work with modern backend, RAG, and LLM technologies.

I've built AI Notes Generator, a Java and Spring Boot document-learning platform that turns uploaded PDFs into summaries, flashcards, quizzes, explanations, and context-aware responses. I designed its RAG pipeline with Spring AI, Redis Vector Store, Ollama, MongoDB, semantic search, and persistent conversational memory.

I've also developed a secure Spring Boot journal application with MongoDB and AI-generated summaries and sentiment analysis, an IBM Watson chatbot with recommendations across 20+ genres, and a Java AWT hotel management system backed by MySQL and JDBC. I focus on clean architecture, reliable REST APIs, and continuously learning modern backend and AI technologies.
