Pain-led pages • Single CTA • One paid technical assessment

Real business problems I fix.
Diagnosed honestly. Solved by an engineer.

If you can name the symptom, I can name the cause. Each fix is scoped to one named problem, with a defined end and a clean handover. Not another plugin. Not another retainer.

Find your problem

Pick the one that sounds like your week.

Each route opens to a deeper page that names the failure modes and the engagement that fixes them. Pain-first, named the way you would search for it.

Vibe coding got you to a demo. Now you need a system.

Your AI-built prototype demos beautifully. The moment it has to handle real customer load, the security, structure, scaling, maintenance, and support gaps the AI never wrote become your problem.

Shopify works. The workflow does not.

POS sync failures. B2B store credit you cannot apply on draft orders. Service bookings that do not fit checkout. FBA orders that break inventory. Apps and spreadsheets only half-solve these.

WooCommerce keeps breaking in ways nobody can explain.

Intermittent database errors that survive every host call. Login friction that five plugins cannot fix. Plugin conflicts you cannot pin down. Codeable Certified Expert. 150+ WooCommerce projects since 2011.

The business has outgrown its spreadsheets.

Inventory counts wrong by the time anyone reads them. Purchase orders managed across three tabs. Product data taking a third of the week. Time to replace the spreadsheet with a real system.

Pages that rank in Google and get cited in ChatGPT.

Search visibility is now two surfaces, not one. Pages built to rank in Google search results and to be cited in ChatGPT, Claude, Perplexity, and Gemini answers. One system, two ranking surfaces.

Why generic fixes fail

The five reasons most fixes do not stick.

More plugins create new failure points.

Every plugin is a dependency on someone else's update schedule, security record, and willingness to keep the plugin alive. Plugin chains tend to fail in the order you cannot debug.

More AI prompts produce code nobody can maintain.

Asking an LLM to fix the code it just wrote works for the first three iterations and then drifts. The codebase ends up with seams nobody understands.

More spreadsheets push the failure later, not away.

When the spreadsheet is the system of record, every new staff member is a new way for the data to drift.

More retainers reward hours, not outcomes.

A retainer pays the agency to be busy. A scoped fix pays for the fix.

Free audits give the consulting away.

The audit is the engagement. A free audit trains the wrong expectation before the engagement starts.

Timeline

Typical Engagements

Not a monthly retainer. A scoped fix, named at the start, finished at the end, with a clean handover.

  • Assessment: paid, two to four hours of focused work, written diagnosis returned within a week.
  • Diagnosis: a written document naming the cause, the failure class, and the recommended path.
  • Fix path: options, with effort and cost shape for each.
  • Sprint: the fix itself, scoped to the named outcome.
  • Handover: documentation, runbook, and the path to support if needed.
Direct Access

One engineer. The whole engagement.

No account managers. No handoffs. You work directly with Anton from first conversation to final handover.

Amazon FBA Shopify Inventory Sync: Why Marketplace Connect Is Not Enough, And How I Would Reconcile

FAQ

Frequently Asked Questions

Is this a retainer?

No. Each fix is scoped to one named problem with a defined end and a clean handover.

Will I be passed to a junior or an offshore agency?

No. You work with Anton directly. If scope expands beyond direct work, the engagement is named and routed, not handed over.

Is the assessment free?

No. Free audits give consulting away before the engagement starts. The assessment is paid and produces a written diagnosis you can act on regardless of whether you proceed with the fix.

How long does the assessment take?

Two to four hours of focused work, plus a written diagnosis returned within a week.

Do you fix problems on platforms not listed here?

Often, yes. The clusters listed are the highest-volume ones. The assessment confirms whether your problem fits.

What does the assessment produce?

A written diagnosis, a fix path with options, and a scoped engagement quote. You keep the diagnosis whether or not you book the fix.

How this works

Three routes, one diagnosis.

Anton, direct, for specialist rescue, custom builds, and integrations. Villiers Vision Works for broader systems and platform work. Private AI-app consultation where a governed AI pipeline is the right fix. The assessment names the route. You decide.

Name the symptom. I will name the cause.

One form field. One or two sentences describing what is broken. Phone and email visible if you would rather call.
