Senior Cloud, DevOps & SRE Consultant
I've spent 15 years in cloud and DevOps, most of it building platforms, leading cloud migrations and running the teams that keep production up.

I've built and led a DevOps team, and I've mentored engineers through an online cloud-engineering program. Teaching the craft matters to me as much as writing the code.
Today I work remotely as an independent consultant. I help teams deploy new applications, modernize older setups and speed up delivery, and I stay your single point of contact from the first call to the last deploy.
What I work with
The tools I use day to day, in client work and in the tutorials.
- AWS
- GCP
- Kubernetes
- Terraform
- Docker
- GitHub Actions
- GitLab CI
- Argo CD
- Prometheus
- Grafana
- PostgreSQL
- Vault
How I Think About Infrastructure
Revisit old decisions.
Most cloud waste comes from a sizing choice that made sense once and was never looked at again after traffic changed.
Test the recovery path.
I only trust backups and rollbacks that someone has run outside of an incident. A drill on a quiet Tuesday is the cheapest place to find a gap.
Make the safe path the easy one.
Good infrastructure gives engineers guardrails and self-service, so doing things properly is also the fastest option.
How I Work With Teams
I work in your repos, with your engineers.
Changes go through your own pull requests and CI/CD, reviewed by your team as we go.
Every change comes with an explanation.
I document what I change and pair with your team on it, so they can maintain and extend it after I leave.
You can reach me during the engagement.
Questions get answered in your Slack or standup the same week.
Outside of client work, I'm still the person who notices when something's off and wants it fixed. If we end up working together, that's the same attention you're getting.
