The Challenge

A growing SaaS platform needed a scalable, monitored, and secure infrastructure that could be deployed across multiple VPS servers with zero-downtime updates and comprehensive observability.

The Solution

Designed and implemented a complete microservices infrastructure deployed across multiple VPS servers. Set up containerized services with Docker Compose (11 services with health checks and resource limits), internal service mesh with Nginx reverse proxy, and secure inter-server networking via WireGuard VPN.

Built comprehensive monitoring with Prometheus (metrics collection), Grafana (dashboards and alerting), and Loki (log aggregation). Automated deployments via GitHub Actions CI/CD pipeline with SSH-based deployment, maintenance mode, and health check verification.

Data layer includes MongoDB + MySQL databases, Redis caching, RabbitMQ message queues, and MinIO object storage — all containerized with proper volume management.
