My goal was different: create a reusable runtime that developers can embed directly into Java applications with memory, planning, reasoning, and hybrid retrieval.</p> <h2> Why I built it </h2> <p>While building Spring Boot applications, I found that adding AI often meant stitching together multiple services. I wanted a deterministic runtime that provides:</p> <ul> <li>Hybrid RAG with PostgreSQL pgvector</li> <li>Episodic and semantic memory</li> <li>Planning and reasoning modules</li> <li>Multi-agent orchestration</li> <li>Privacy-first architecture</li> <li>Java 21 native SDK</li> </ul> <h2> Architecture </h2> <p>The platform follows a layered architecture:</p> <ol> <li>Application Layer</li> <li>SDK Layer</li> <li>Runtime Orchestration</li> <li>Kernel Services</li> <li>LLM Provider Layer</li> </ol> <p>Every request flows through an explainable cognitive pipeline instead of directly calling an LLM.</p> <h2> Developer Portal </h2> <p>I also built an official documentation website using <strong>Next.js 16</strong>, <strong>React 19</strong>, <strong>Tailwind CSS 4</strong>, and <strong>Framer Motion</strong>.</p> <p>It includes:</p> <ul> <li>Architecture documentation</li> <li>SDK reference</li> <li>Quickstart guide</li> <li>Security model</li> <li>Interactive playground UI</li> </ul> <h2> Tech Stack </h2> <ul> <li>Java 21</li> <li>Spring Boot</li> <li>PostgreSQL + pgvector</li> <li>Next.js 16</li> <li>React 19</li> <li>Tailwind CSS 4</li> </ul> <h2> Feedback Welcome </h2> <p>This is still a <strong>Developer Preview</strong>, and I'd love feedback from Java and backend developers.</p> <p>GitHub: github.com/darshanrathod04/shree-ai-os</p> <p>Website: shree-ai-os.netlify.app</p> <p>Thanks for reading!</p> java springboot opensource ai
