What we do
From GPU clusters to zero-trust pipelines
Each of our consultants combines deep hands-on expertise in Linux, security and automation with modern AI platform operations, so you can deploy, govern and optimise complex workloads with confidence.
AI & ML infrastructure
GPU-optimised clusters, MLOps pipelines on OpenShift AI and SUSE AI, model serving, vector databases and LLM training and inference environments.
DevOps & DevSecOps
Secure CI/CD, GitOps and infrastructure as code with Terraform, Ansible, Argo CD, GitLab, Jenkins and GitHub Actions, with security built into every stage.
Cloud-native & hybrid platforms
AWS, Azure and Google Cloud alongside Red Hat OpenShift, SUSE Rancher/RKE2 and on-premise Kubernetes, governed and cost-optimised.
Cybersecurity & compliance
Vault PKI, zero-trust service mesh, supply-chain security, vulnerability management, SIEM and compliance automation (ISO 27001, PCI, SOX, CIS).
Observability & automation
Prometheus, Grafana, OpenTelemetry, Splunk and Elastic: telemetry across large AI, HPC and cloud estates, with alerting that people trust.
Training
Hands-on courses in Linux, UNIX, Kubernetes, OpenShift, security and automation, onsite or virtual, tailored to your team.

Latest insights
Notes from the lab
We test what vendors promise before we recommend it. Recent write-ups:
Agentic SecOps on one workstation
Rebuilding the SUSE AI Factory and NVIDIA stack with open source (SLES 16, RKE2, GPU Operator, OpenShell), then verifying seven security claims, from deny-by-default egress to filesystem protection and audit logging.
Observability for RAG pipelines
Wiring Langfuse into a retrieval-augmented generation pipeline to trace, measure and debug LLM behaviour in production.
Building a 5-node AI agent
What LangGraph actually teaches you about agent design, with reproducible code and container images.

How we work
Senior engineers who deliver, document and hand over
We lead strategy and governance for AI and platform modernisation, then roll up our sleeves to build it:
- Architecture, roadmaps and stakeholder engagement for secure AI operations
- Everything as code: Terraform, Ansible, Helm, Packer and GitOps
- Security and compliance built in, not bolted on
- AI-assisted engineering with strict guardrails and evidence-based review
- Knowledge transfer and training so your team owns the result
