Platform engineering, done in the console.

OnlyASCII Ltd is the consultancy of Panagiotis (Panos) Xynos — a software engineer who has spent his career making fragile systems reliable. Deep Cloud Foundry and BOSH expertise, real open-source contributions, and a build toward self-healing, AI-assisted infrastructure.

What we do

Cloud Foundry & BOSH

Deep, rare expertise running Cloud Foundry platforms — from greenfield deploys to day-2 operations and decommissioning.

SRE & Production Engineering

Reliability built in, not bolted on. Proactive operations, observability and a blameless culture.

Automation & IaC

If it's boring and repetitive, it gets automated. Infrastructure as Code from the ground up.

AI-Assisted Engineering

Bringing agentic systems and AI-assisted development into the operational loop — pragmatically.

Open source

Credibility you can verify. Selected contributions to the Cloud Foundry & BOSH ecosystem:

Loggregator — mTLS — Implemented mutual-TLS (mTLS) support for the Loggregator component, the Cloud Foundry logging and metrics system.
Concourse-Up — Led the rewrite in Go of the platform automation tool, enabling one-command Concourse deployments to AWS and GCP.
BOSH releases & packages — Authored and maintained open-source BOSH releases and packages — Redis, Kafka, a modern python3 package, and HA Postgres / HA Redis.

Where we're heading

Autonomous, self-healing platforms

The best SREs aren't firefighters. The next step is platforms that observe, learn and recover on their own — agentic systems and AI-assisted engineering folded into the operational loop, with a sprinkle of immutability. Rust and WASM as portable, self-contained tooling for fault detection and recovery.

OnlyASCII Games

The other half of the name. We're building ASCII / text-driven games that trigger the mind the way multi-user dungeons did in the 90s — depth over spectacle, imagination over pixels. Nothing published yet. Watch this space →
