Pragmatic DevOps engineering — from platform reliability to CI/CD at scale. Available for freelance consulting and senior engineering roles.
How I work
A deliberate, repeatable approach — no matter the stack or scale.
Diagnose the real constraint
I start by identifying what is actually limiting you — latency, reliability, deploy risk, or toil — not the symptom.
Design small, testable changes
Architecture proposals and rollout plans shaped to be incremental — minimise blast radius, maximise learning speed.
Automate & document the path
CI/CD pipelines, IaC modules, and runbooks that let your team move safely without relying on tribal knowledge.
Measure impact & iterate
SLOs, error budgets, and cost signals to validate the change worked — and a feedback loop built in from day one.
What I can help with
Focused areas where I bring hands-on experience and proven results.
Platform Hardening
Incident readiness, backup strategies, least-privilege IAM, security baselines, and runbook culture that reduces downtime.
CI/CD
Safer releases, faster pipelines, reproducible builds — GitHub Actions, ArgoCD, GitOps workflows designed for team scale.
Observability
Logs, metrics, and traces that actually answer production questions — not just dashboards for the dashboard's sake.
Cloud Infrastructure
Terraform, containerisation, networking, AWS multi-account patterns, and IAM designs that scale teams, not just workloads.
Python Services
Pragmatic microservices, async workloads, and API reliability — FastAPI first, well-tested, production-ready from day one.
Training & Mentoring
DevOps bootcamp instruction, internal workshops, and 1-on-1 mentoring for engineers moving into platform and infrastructure roles.
Recent projects
A handful of engagements that illustrate how I think and deliver.
K8s Observability Platform
Designed and deployed a full-stack observability platform on Kubernetes using Prometheus, Grafana, Jaeger, and OpenTelemetry — reducing MTTR by 40%.
GitOps CI/CD Pipeline
Rebuilt a fragile Jenkins monolith into a GitOps workflow with ArgoCD and GitHub Actions, cutting release lead-time from 5 days to 2 hours.
Terraform Cloud Foundation
Architected and delivered an AWS multi-account landing zone with Terraform modules, SSO, and security baselines across 12 accounts from scratch.

Technical thinking, written out - so the ideas are reusable.
Why your CI pipeline is lying to you
Green builds that hide flaky tests, coverage gaps, and configuration drift. Here is how to make your pipeline an honest signal again.
The SLO conversation your team isn't having
Error budgets only work when the whole team — product, engineering, and operations — shares ownership of reliability as a feature, not an afterthought.
Terraform at scale: why module boundaries matter
The difference between a Terraform codebase that scales and one that becomes a bottleneck often comes down to one decision made on day one.
Have a platform problem
worth solving?
Whether you need a fractional DevOps engineer, a one-off infrastructure audit, or someone to lead a team through a reliability transformation — let's talk.
