DevSecOps & Platform Engineering Tech Lead

I built the IaC platform hundreds of repositories run on, and I build Claude Code agents for infrastructure work.

AI & Claude Code

I use Claude Code as an everyday engineering tool, not a chat window. I built and maintain my team's plugin marketplace: skills, agents and MCP integrations that carry our standards for Ansible, Terraform, Go and CI. With them, a Terraform module takes days instead of weeks, and an Ansible role takes a day instead of a week.

How it fits my day

  1. Start of a change: clone every repository involved in one step, and agree a plan before any code changes.
  2. Writing: roles, modules and Go code start from the team templates, so review is about the change, not the layout.
  3. Before every commit: the same linters as CI run locally and fix what they can.
  4. Large rollouts: an agent that knows the estate helps design changes across many roles, which then roll out in small batches, with every pipeline run.
  5. Paperwork: tickets and commit trailers follow the team conventions without a checklist.

Plugins I use most

  • ansible

    daily

    Create, check and test Ansible roles to the team's standard.

    New roles start from the standard layout (detect, install, configure, update; prefixed variables; fully qualified modules). Existing roles are checked and auto-fixed before review, and molecule test suites are scaffolded role by role. The agent helps design changes that span many roles and hosts.

  • pre-commit

    daily

    Install and run the team's containerised linters.

    Runs ansible-lint, yamllint, terraform fmt, tflint and JSON/YAML checks in the same container image as CI and fixes what it can, so lint failures show up on my machine instead of in a shared pipeline.

  • jira

    daily

    Write tickets to the team's conventions.

    Turns a piece of work into an epic and tasks with the required structure and content, and links them to commits and merge requests through commit trailers.

    jira-tickets

  • terraform

    Scaffold config-driven Terraform modules and providers.

    New modules follow the team's YAML-driven layout with input validation, and new providers use the Terraform Plugin Framework. This is where delivering a Terraform module went from weeks to days.

  • golang

    Idiomatic, tested Go for services and CLIs.

    Scaffolds Go services and CLIs, writes table-driven tests that run under the race detector, reviews code with the standard linters, and proves performance changes with benchmarks and profiles.

  • glab

    GitLab CLI setup and batch cloning.

    Sets up the GitLab CLI on a new machine and clones whole groups or lists of repositories at once, the first step of any change that touches many repositories.

Public example: video-summary, a Claude Code plugin that turns a folder of camera footage into a summary video.
