Panagiotis (Panos) Xynos — SRE / Production Engineer, and the person behind OnlyASCII Ltd.
I consider myself, primarily, a software engineer — one who acted on the frustration of continuously breaking systems and decided to find and fix the root causes. Early in my career I started automating anything that felt like a boring or repetitive task, and found I had a knack for it.
I was acting as a DevOps or Site Reliability Engineer before those roles had names. From the mainframes of yesteryear to the cloud-native architectures of today — Puppet, Chef, Jenkins, Vagrant; I was there. Infrastructure as Code, continuous integration and containerisation came as a natural evolution. I can’t go back to anything else. I want to go beyond.
The best SREs are not firefighters. Be proactive, observe and learn. Anyone can react to incidents with the proper, continuous training.
My natural curiosity has pulled me through many IT roles, which makes me a good R&D person — the glue between backend, frontend, mobile and (cloud) platform teams. That confuses people, but it’s my strength: I understand the different layers of a system and how they interact, which helps me spot bottlenecks and failure points before they bite. From COBOL to Go, from CloudFormation to Terraform.
These days I experiment with agentic systems, AI-assisted development, and “dark factories,” and with Rust and WASM — which feel like a natural fit for portable tooling. WASM might be the next containerisation, after all. I want to build portable tools that automate fault detection and recovery — maybe even a self-healing system that fixes itself without human intervention, with a sprinkle of platform immutability in the mix.
We primarily work with people. Sometimes process — not technology — is the root cause. I see every system I work with, software and hardware alike, as a live organism: things interact and depend on each other deeply, which is why cascade effects are so common in this line of work. I prefer environments that embrace automation, proactive monitoring, and a blameless post-mortem culture.
