STACK / TOOLCHAIN
Tooling is not an identity. It's a means to control execution.
All choices are evaluated for:
• performance under concurrency
• composability without abstraction hell
• zero-fat deployability
Langs: Go, C, Python
State: PostgreSQL, Redis, SQLite
Transport: gRPC, NATS, Kafka
Infra: Docker, K8s (when it matters)
Obs: Prometheus + traces
