Built for agencies

I plug into your delivery to unblock work, reduce risk, and keep WordPress releases predictable.

When agencies bring me in

  • Inherited builds and messy handovers
  • Releases feel risky (regressions creeping in)
  • You need a senior pair of hands to unblock delivery
  • You want maintainable implementation — not quick hacks
  • You need reliable ownership and ongoing support

What you get

  • Calm, senior engineering mindset and clear comms
  • Staging-first delivery with sensible checks
  • Maintainable code and documented handover
  • Pragmatic improvements (not forced rebuilds)
  • Less firefighting, more predictable delivery

Engineering support, end-to-end

Audit & Roadmap

De-risk inherited builds with a clear, prioritised plan

Code/theme/plugin review (risk + maintainability)

Performance and stability quick wins

Security posture and update process

Prioritised backlog with next steps

Bespoke Development

Themes, blocks and plugins built to be maintainable inside agency workflows.

Custom blocks / theme work (ACF/Gutenberg as appropriate)

Plugin/feature development and integrations

Defensive coding for real-world content + editors

Clean handover and documentation

Workflow & Deployment

Make delivery predictable with staging-first releases and a sensible process.

Git workflow tidy-up and conventions

Staging → QA → release checklist

Rollback readiness (backups, deploy plan)

Build pipeline tidy-up (npm/gulp/Tailwind artefacts)

Maintenance & Support

Ongoing support that keeps sites stable, secure and monitored.

Staged updates with verification steps

Monitoring: uptime, errors, security signals

Proactive fixes before they become incidents

Monthly summary + recommendations

A low-risk way to improve WordPress

I’m used to dropping into existing agency workflows — inherited builds, tight timelines, and “we need this to stop breaking” situations. My approach is designed to reduce risk, keep stakeholders calm, and make delivery predictable.

1) Consultation
We’ll talk through your setup, what’s currently painful (stability, performance, process, support), and what a sensible next step looks like. If it’s clearly scoped, we can go straight to a defined sprint.

2) Audit / diagnostic (when scope is unclear)
If there’s technical uncertainty or risk, we start with a short audit. You’ll get a prioritised roadmap: quick wins, medium-term fixes, and longer-term recommendations — with clear reasoning, not guesswork.

3) Implementation sprint(s)
Work is delivered in defined modules: maintainable code, staged changes, and a sensible release checklist. I’m happy to work in your repo and processes — or improve them if they’re currently fragile.

4) Ongoing support
For teams who want it, I provide maintenance and support that’s staging-first and monitoring-led. The goal is fewer surprises: stable updates, proactive fixes, and a site that’s easier to run month after month.

If scope is unclear, I’ll always recommend an audit first — then implementation in clearly defined modules.

Questions, answered — no drama

Most projects go smoothly when expectations are clear. Here’s how I work, what I need, and how we keep changes low-risk.

What happens on the consultation call?

We’ll talk through your current setup, what’s painful right now (stability, performance, workflow, support), and what “good” looks like for your team. If it’s clearly scoped, I’ll suggest a practical next step. If there are unknowns, I’ll recommend a short audit/diagnostic first so we can reduce risk.

Do we need to start with an audit?

Not always. If the work is already well-defined (e.g. a specific feature build), we can go straight into an implementation sprint. If the codebase is unfamiliar, inherited, or the issues are broad (“it’s slow / it keeps breaking”), an audit is usually the quickest way to get clarity and prioritise the right fixes.

Can you work inside our Git/review process?

Yes — I’m happy to work inside your existing repo, branching strategy and PR/review flow. If your process is currently a bit fragile, I can also help tighten it up (staging-first releases, checklists, rollback planning and clearer handover).

How do you handle releases safely?

I work staging-first wherever possible. Changes are tested in staging, then released with a simple checklist and a rollback plan (backups/restore readiness, or a known revert path). The goal is fewer surprises on live and less firefighting for your team.

Do you offer ongoing maintenance and support?

Yes. I can provide ongoing support that covers staged updates, monitoring (uptime/errors/security signals), and proactive fixes. The aim is to keep sites stable and predictable, not just “run updates and hope”.

Do you do custom development as well?

Yes — bespoke theme, block and plugin development is a big part of what I do. The difference is it’s built to be maintainable in a real agency environment: clean structure, sensible conventions, and documentation so your team isn’t dependent on one person.

Can you help without rebuilding the site?

Often, yes. Many improvements come from targeted fixes: cleaning up problem plugins, improving caching, tightening the release workflow, and addressing stability/performance hotspots. Rebuilds are only worth it when the underlying architecture really can’t support what you need.

What access do you need to get started?

Typically: WordPress admin, hosting access (or the ability to deploy to staging), and repo access if code changes are involved. For workflow work, access to your CI/deployment setup is helpful. We’ll confirm exactly what’s needed on the consultation call.

How quickly can you start?

If it’s urgent (site down / critical bug), I can often help stabilise quickly. For planned work, we’ll agree dates and scope after the consultation.

Do you work with direct clients too, or just agencies?

I work with various agencies, but I also work with in-house teams and business owners when the need is the same: a WordPress platform that must be reliable, secure and maintainable.

Testimonials

Most of my work is embedded in agency delivery: unblocking tricky issues, improving workflows, and shipping maintainable WordPress.
