Architecture - microservices mostly connected through GraphQL and gRPC (certificate based auth is the shit) Languages - Java for backend, pure JS for frontend Frameworks - Spring Boot on backend, pure React on frontend (I like to keep it simple) Infrastructure - Mostly k8s (with helm to make life easier), Nix for more complex stuff Databases - Postgres, Mongo, Redis, Elastic... Really depends on use-case...
