Cloud systems,
built to hold up.
b6n is an independent cloud and DevOps consultancy run by Luke Buchanan, a Senior DevOps Engineer based in Belfast. I help teams untangle Kubernetes, improve delivery, make production easier to understand and remove operational toil. I also build focused software, from portfolio sites and APIs to internal tools. You work directly with me from diagnosis to handover.
Where I can help
Focused help for platform and software work that is blocking you.
Cloud foundations
GCP architecture, Terraform, IAM and networking, with permissions, state and running cost considered from the start. New environments, migrations and difficult clean-up work.
Kubernetes and delivery
GKE platforms, Helm, Argo CD and CI/CD pipelines that give teams a clear, repeatable path from commit to production.
Reliability and observability
OpenTelemetry, Datadog, Cloud Monitoring and Prometheus, with useful SLOs and alerts tied to action rather than noise.
Software and automation
Portfolio sites, internal tools and APIs in TypeScript and Node.js, plus Bash and Python automation for repetitive operational work. Practical AI where it earns its place.
How I work
A clear process, with your team in control.
Diagnose first
I start with the current system, the failure mode and the constraint. You get a clear view of the problem before I propose a build.
Keep changes reviewable
Work is split into small, testable steps, with production impact and rollback considered before each change.
Leave you in control
Infrastructure, code and documentation stay understandable to your team. The goal is ownership, not dependency.
Be candid
If the right answer is to fix less, use what you have or bring in someone else, I will say so early.
