    "displayName": "High-Performance API Server Stack (Go, Chi, PostgreSQL, Redis, Prometheus)",
    "description": "A low-latency, high-throughput REST API server built on Go and the\nChi router for its lightweight middleware chain and stdlib-compatible\nhandler signatures. PostgreSQL with the pgx driver provides connection\npooling and prepared-statement caching for sub-millisecond query\nlatency. Redis handles response caching, rate limiting, and distributed\nlocks. Prometheus and Grafana deliver real-time observability with\np99 latency histograms and error-rate alerts. Docker enables consistent\nbuilds and deployment to Kubernetes or bare-metal. This stack excels\nwhen throughput matters — Go's goroutine scheduler handles tens of\nthousands of concurrent connections with minimal memory overhead. The\ntradeoff is a smaller ecosystem of ready-made libraries compared to\nNode.js or Python, so teams must build more plumbing themselves.\n",
