About Jeff
Hey — I'm Jeff. I've spent the last decade in the trenches of DevOps and platform engineering, working with teams ranging from scrappy startups to large-scale distributed systems. I started JeffOps because I was tired of content that was either too shallow or too academic.
Everything I write, record, or present is grounded in real production experience. If I haven't run it at scale, I won't write about it as if I have. The blog, newsletter, and YouTube channel are my way of giving back to a community I learned everything from.
What I Focus On
My sweet spot is the intersection of platform engineering, DevOps culture, and cloud-native infrastructure. I care deeply about developer experience — the idea that the right internal tooling and processes unlock engineering velocity in a way that no amount of "move faster" top-down pressure ever could.
I'm currently exploring: eBPF-based observability, platform engineering maturity models, and AI-assisted operations (the real stuff, not the hype).
My Stack
Kubernetes / k3s
ArgoCD / Flux
Terraform / OpenTofu
GitHub Actions
Prometheus / Grafana
OpenTelemetry
Vault by HashiCorp

Consulting & Advisory
I help engineering teams ship faster by fixing the system around them — not just the code.
With a decade of hands-on platform and DevOps experience, and a more recent move into engineering leadership, I work with CTOs, VPs of Engineering, and tech leads who want to level up their teams — technically and organisationally.
// services
What I Offer
Fractional Engineering Manager
Embedded part-time EM for teams that need leadership continuity during a hire, a gap, or a growth phase. I run 1:1s, unblock engineers, coordinate with product, and give you honest assessments of what the team actually needs.
Engineering Team Assessment
A structured 4-week deep dive into your team's processes, tooling, culture, and delivery. Plain-language report with prioritised recommendations — no consultant jargon.
Tech Lead & New EM Coaching
1:1 coaching for engineers stepping into leadership for the first time. Bi-weekly sessions covering the IC-to-EM transition, difficult conversations, team health, and personal effectiveness as a leader.
Platform Engineering Advisory
Strategic advice on building or scaling an internal developer platform. From golden path definition to team topology decisions, I help platform teams articulate their value and build for adoption.
Workshop Facilitation
Half-day or full-day workshops for engineering teams and leadership groups. Topics: Team Topologies mapping, DORA metrics baseline, incident culture, or the IC-to-EM path.
Advisory / Sounding Board
A standing monthly call for CTOs and VPs of Engineering who want an experienced outside perspective on org design, hiring decisions, technical strategy, or team health.
// approach
How I Work
I don't arrive with a framework and leave with a report. I get involved in the work — sitting in on standups, reading your RFCs, talking to your engineers — and give you observations from the inside, not the balcony.
I work with a small number of clients at a time — usually no more than three engagements concurrently — so you get real attention, not templated advice.
