This deep dive covers Go 1.24/1.25 new features (iter.Seq, range-over-func, swiss-table maps, PGO, weak pointers, slog), web frameworks (Echo, Gin, Fiber, Chi, Kratos), the DB stack (sqlc, pgx, ent, gorm, bun, atlas), gRPC vs Connect-RPC vs Twirp, the Bubble Tea/Cobra CLI ecosystem, DI (wire, fx, do), Buf protobuf workflows, testing (testify, gomock, mockery), and real adoption stories from Toss, Naver, Mercari, and CyberAgent.
