Hi, your VDocs project sounds exciting—I can help take the MVP from prototype to production-ready. I’ve built backend systems with PostgreSQL, secure APIs, and real-time features used by thousands of users, so I’m comfortable with your scope: appointment booking, patient report management, and ABDM integration. I have experience with Java (Spring Boot) + Postgres, but if you’re open to alternatives for scalability, I’d also suggest Go (Golang) for the backend. In my past projects, moving from Node/Python to Go reduced processing times by up to 90% while keeping APIs lightweight and reliable—important for healthcare-grade apps. I can ensure secure API design, optimized schemas, and smooth integration with your Flutter frontend. Happy to share previous work and discuss the best approach.
