Infrastructure as Code and Automation
Terraform-based infrastructure and deployment automation that removes manual steps and stays maintainable after handover.
Cloud Cost Optimization and FinOps
Structured cost reviews and FinOps practices that reduce cloud spend without degrading reliability or slowing delivery.
DevSecOps and Delivery Pipelines
CI/CD pipelines with security controls built in: fewer manual steps, auditable releases, and scanning that engineers actually keep.
AI infrastructure
AI infrastructure readiness.
Before introducing AI workloads, assess the compute, storage and networking requirements alongside access controls, observability and cost.
A readiness review identifies infrastructure constraints and produces a prioritized assessment before implementation. My NVIDIA NCA-AIIO certification supports this extension of my cloud and platform work.

Immutable Infrastructure Meets NIS2: The Case for Minimal, Hardened Container Hosts
Azure Linux 4.0-style minimal hosts — no GUI, SELinux enforcing by default, atomic rollbacks — are becoming the compliance-friendly default for container fleets. The operational and regulatory case, the migration friction nobody advertises, and an opinion on timing.
Backups, Replication, and Recovery: Three Budgets, Not One
Why 'we have backups' is not an answer to a continuity question, and how engineering leaders should structure — and test — recovery before an incident or an audit forces the issue.
When to Move to Managed Cloud Services — and When to Wait
Decision criteria for CTOs weighing managed databases, Kubernetes, and serverless against self-operated infrastructure: the real cost comparison, the migration signals, and the lock-in question answered honestly.
