You will get Probezilla::System to monitor your indie websites without complexity
Project details
ProbeZilla is a simple, hosted status page service for self-hosters. It monitors URLs and provides a clean, shareable page showing service health status. The system is designed as a decomposable monolith following DDD principles for future microservices scaling. Incident reporting, alerts, performance stats for urls.
Monitoring Architecture
**Smart Distribution Strategy:**
• Redis-backed job queue using sorted sets (ZRANGEBYSCORE)
• Atomic Lua script (`atomic_claim.lua`) for lock-free job claiming
• Token bucket for global probe rate limiting (configurable via `GLOBAL_PROBE_RATE_PER_SEC`)
• Backoff mechanism for failing endpoints to reduce load
• Worker concurrency control (configurable via `WORKER_CONCURRENCY`)
**Job Queue:** Redis sorted set with atomic Lua claiming prevents race conditions and enables horizontal scaling.
**Rate Limiting:** Token bucket pattern ensures global probe rate stays within limits, protecting monitored services.
**Backoff Strategy:** Endpoints with consecutive failures get exponentially increasing check intervals (`backoff_enabled` flag).
Built with Quarkus, Postgres, Redis, React 18, Tailwind 4

Supabase Auth and Row Level Security Setup
Subhrajyoti built the entire secure backend for my platform and the quality was outstanding. Role-based access control, proper data isolation, auditor and agent modules — all production-grade and on time. He caught and fixed his own regressions before they ever reached production, gave me verifiable proof at every stage, and even hardened the app pre-launch at no extra cost. Sharp, honest, and fully invested in getting it right. Would hire again without hesitation.
