I've built the backend for Vitruvian Shield's multi-functional web platform from scratch, delivering services for user profiles, news, ticketing, and payments.
I implemented Google-based registration and authentication flows, along with Azure Communication Services integration and cache-based access-token management.
I designed signed server-to-server authentication between the website and dashboard backends using shared secrets, nonces, timestamps, and request content to validate integrity.
I've extended dashboard APIs, resolved backend issues, automated publishing to YouTube and LinkedIn, and developed new FastAPI and gRPC services for inter-service communication.
