Building reliable software in the real world
Hi, I’m László Simon — a Senior Software Engineer based in Switzerland with experience in large-scale enterprise systems, software architecture, DevOps, and IT security.
On this site, I share practical insights about:
- Common programming mistakes that cause real production issues
- Software architecture and domain-driven design in enterprise environments
- Distributed systems and microservices (what works and what doesn’t)
- Rust, Java, and modern backend development
- IT security topics, from application security to infrastructure
Everything here is based on hands-on experience from real projects — not theory.
