Virsion, a two-person startup, built a secure RAG-based document management platform using Vaadin 24 and Spring Boot. Their server-side-first architecture eliminates exposed API endpoints, keeping AI orchestration within the JVM boundary. The stack integrates Spring AI with Azure AI Search and Azure OpenAI for vector storage and LLM queries. Vaadin's built-in WCAG 2.1 compliance enabled accessibility-first development tested with blind users. The team estimates saving over a month of development time compared to React or Angular, reaching a functional beta in weeks.
