Sofon

Self-hosted uptime monitoring you deploy on your own infrastructure — no SaaS fees, no data leaving your network.

Features:

• Engineered a zero-dependency, self-hosted uptime monitoring engine by embedding a Next.js SPA into a highly concurrent Golang backend
• Architected a scalable HTTP executor using Go worker pools and Redis to process custom health assertions (status codes, latency SLAs) across thousands of concurrent checks
• Developed a robust Result Processor that categorizes network errors, manages retry queues via Redis, and triggers real-time alerts without false positives
