I deliver a fixed-scope, 5-day sprint to build a production-ready Go backend: a REST or gRPC service with 3 - 5 endpoints, JWT auth, pagination/validation, PostgreSQL schema + migrations (optional Redis), Dockerfile/docker-compose + Makefile, Prometheus metrics, a starter Grafana dashboard, 10 - 15 unit tests, and a clear README/runbook. What makes me unique is an observability-first, DevOps-minded approach, code that’s measurable, maintainable, and easy to run, backed by a predictable process (Day 1 discovery, Days 2–6 build/tests, Day 7 handover) and a 14-day bug-fix warranty
