About

I'm Ronan O'Brien — technical bridge between engineering and the C-suite. I help 50-100 person firms leverage infrastructure, security, and delivery patterns that large enterprises use, without the overhead of big-firm consulting.

With a BA (Mod) Business & Economics from Trinity College Dublin and 8+ years in DevOps and SRE, I translate technical risk, opportunity, and trade-offs into boardroom-ready language. My value is teaching SMBs to make confident infrastructure decisions that align with business outcomes.

I'm Ronan. I translate enterprise-grade cloud infrastructure into tools small teams can actually use. If you're a startup or SMB already paying for Azure or AWS and not getting the value—or you're growing fast and need platforms that won't break—I can help.

My edge is making the complex practical: taking the IaC, monitoring, and security patterns that work at scale and adapting them for 10–100 person teams. You get enterprise reliability without enterprise overhead.

I work across Azure and AWS with a bias for Terraform, GitOps, and pragmatic observability (Grafana, Datadog, Splunk). I also coach teams—training juniors, lifting delivery maturity, and keeping stakeholders aligned when things get technical.

I'm most useful when you need someone who can speak both "boardroom" and "engineering": translating risk, cost, and delivery trade-offs into decisions your organisation can act on.
