An ordinary Monday morning, no stage and no audience, I found out I鈥檇 reached 10th place among the contributors to quarkus-langchain4j in the world. The story of how I got there in 5 months, and what changed along the way.
Build an AI agent that calls real REST APIs as tools, without writing any orchestration logic. REST Client + @Tool = automatic tool. The LLM decides when to call, which to call, and with what arguments. Everything runs locally with Ollama via Dev Services, zero API key.
I built the same AI app with LangChain4j, Spring AI, and Quarkus LangChain4j. One of them took 92 lines. The others took 192 and 180.
