Why and how I migrated my personal projects to a self-hosted Coolify instance, setting up multi-stage Docker builds, automated SSL via Traefik, and Git push-to-deploy.
Hello, world!
I'm Ozgur GurcanIzmir, TR
- I'm a Software Engineer focusing on Backend & Distributed Systems.
- I build high-throughput, resilient microservices.
- Primary tools: Java, Spring Boot, Go, and Kafka.
- Exploring AI agents, MCP tooling, and TypeScript.
- Based in Izmir, Turkiye.
- A builder, continuous learner, and freedom seeker.

I specialize in backend engineering, high-throughput microservices, and distributed systems. Having worked on production systems handling millions of requests per minute, I created this space to document practical architectural lessons, zero-downtime database migrations, and performance tuning.
Beyond backend infrastructure, I enjoy building side projects, experimenting with AI workflows (MCP servers, agents, and modern tooling), and self-hosting. This blog is my digital workbench for sharing engineering notes that solve hard, real-world problems.
