Hello there, We have 8 years of experience in backend API development, microservices architecture, and cloud-based database systems. Your Spring Boot + GraphQL + Azure SQL stack on a monthly basis signals a long-term product build, and that's our sweet spot. We'd use a schema-first approach with Spring Boot's GraphQL starter and DataLoader batching to prevent N+1 queries against Azure SQL. Microservices would communicate via GraphQL federation or REST where synchronous calls make sense — not everything needs a resolver. Spring Boot over Micronaut because Spring Data JPA has mature Azure SQL support, and JUnit 5's test context is battle-tested for mocking GraphQL resolvers. We'd tune HikariCP connection pooling for Azure's connection limits, which trips up teams using defaults. Our primary stack is Python-based, but we've built and maintained Java microservices on government platforms handling 25M+ citizens — containerized services, structured query layers, and thorough test coverage with 60,000+ production records. The patterns transfer directly. Biggest risk on monthly engagements: schema drift between services. We'd enforce contract testing with JUnit alongside GraphQL schema validation to catch breaking changes before production. Week one: project structure, GraphQL schema design, and Azure SQL connectivity — then monthly iterations with weekly standups. Happy to share an architecture diagram. Naveen Brainstack Technologies
