Dave Rix
Senior AWS Cloud Architect, Platform Engineer and MySQL/Aurora DBA. 30+ years building infrastructure that has to stay up.
I architect multi-region AWS platforms, automate them end to end with Terraform, Ansible and Jenkins, and run MySQL and Aurora at scale – including large global Aurora fleets and significant cloud-cost reductions. Lately I weave AI-assisted and agentic coding through the daily workflow, and run a multi-agent organisation on my own hardware.
Selected work
Case studies and technical write-ups – the problem, the architecture, the decisions, and what happened.
Case study: Modernising an AWS estate with Claude Code
Modernising a production AWS estate with Claude Code – migrating Terraform state v3 to v4, the AWS provider to 6.0, and Amazon Linux, PHP and WordPress to current versions – with an honest account of where the AI tool helped and where it did not.

Deriving unique server IDs from IP addresses
AWK scripts for converting between IP addresses and decimal numbers – and why this makes a reliable source of unique server IDs for MySQL replication clusters and other distributed systems.
Building with AI
AI is part of how I work, not a separate hat. Daily Claude Code, GitHub Copilot and ChatGPT across Terraform, Bash and Python – including a substantial Claude Code-driven modernisation of an existing Terraform and AWS estate (component upgrades, WordPress 6 to 7, Amazon Linux 2 to 2023, PHP 7 to 8.3). I also run a multi-agent organisation of 30+ CrewAI agents in Multipass, applying the same production discipline to AI that I bring to infrastructure. OpenClaw is an experimental track I intend to build out further.
