01What I bring

Six ways I help engineering teams ship calmer.

Not a job description. The kinds of problems where I tend to do my best work.

01

Stabilise

Understand the platform, find the real failure modes, and reduce operational noise.

02

Automate

Replace fragile manual steps with code, pipelines, checks and repeatable workflows.

03

Modernise

Move systems forward without losing reliability, recovery, or the people operating them.

04

Mentor

Raise the bar across the engineering function - escalation point, reviewer, teacher.

05

Tool

Small Go and Python CLIs that fit shells, CI, cron and systemd. Built for operators.

06

AI-assist

Use AI where it improves clarity - summarisation, reporting and human-in-the-loop ops.
