Ian Compton is the founder of Revenant Systems Ltd and a software engineer with 20 years of professional experience. He works hands-on across the full stack — back-end services in Go, Node.js, and Python, web and mobile front ends, AI integration, data engineering, and the cloud infrastructure underneath: Terraform on AWS and Azure, Kubernetes, and ArgoCD-driven GitOps.
His deepest experience is in high-volume, real-time analytics and eCommerce personalisation: telemetry pipelines ingesting billions of events a month, and ClickHouse warehouses that have worked through hundreds of billions of high-cardinality rows. He has architected and scaled these systems as an early engineer and later an engineering leader — including a cloud-spend redesign that cut a platform's infrastructure costs by around 60% while its traffic doubled.
Directly. Revenant Systems is a small, senior firm, so you deal with the engineer doing the work — no account layer, no hand-offs. Every engagement starts with evidence: an audit of what actually exists, then a precisely agreed scope before anything is built. Progress is reported plainly, in writing, and the work is handed over clean enough that you aren't dependent on me afterwards.
