I work as a white-label WordPress developer for agencies that need senior delivery without another full-time hire. WordPress, WooCommerce, custom plugins and AI integrations ship under your brand, inside your repo and process, with capacity that flexes with your pipeline.
Every agency hits the same wall: the projects are sold, the deadlines are set, and the people who can build it are already at capacity. Bringing in a dependable external WordPress + AI engineer is often faster, cheaper and lower-risk than a permanent hire you can't yet justify.
A new project lands while the developers you have are committed for weeks. You need senior capacity now, not after a two-month hiring process.
The build has moved past themes and page builders into custom functionality, and it needs someone who has lived in WordPress and WooCommerce internals for years.
Someone left a half-finished build and no documentation. You need a steady pair of hands to pick it up, understand it, and get it to the finish line.
Checkout is fragile, plugins conflict, and every change breaks something else. The store needs stabilising before it costs your client sales.
Your designers produced something excellent in Figma. It deserves a build that respects the spacing, typography and interactions rather than an approximation.
Core Web Vitals are failing, the client has noticed, and launch is slipping. You need the numbers fixed without breaking what already works.
Six ways agencies use me as an extension of their team — with a hard focus on AI agents, automation and WordPress delivery your clients are already asking for.
Senior WordPress and AI capacity delivered under your brand. I stay invisible to your client, so you scale delivery without scaling headcount or diluting the relationship you’ve built.
What clients are asking for now: agents that do real work inside their WordPress stack — not chat widgets that answer FAQs.
Pixel-accurate implementation of your designers’ work. Spacing, type and responsive behaviour built the way they intended, so what ships matches what you sold.
Stable stores that hold up in production. Custom functionality, checkout and integrations built to survive the next plugin update instead of breaking on it.
Core Web Vitals fixed without a rebuild, or a calm takeover when a build has stalled. Root-cause work, not patches that break next week.
Reserved monthly time for updates, small features, AI agents and the steady stream of client requests — so nothing sits in your backlog.
Clients are asking for agents and automation, not another chatbot demo. These are scoped packages you can put on your proposal under your brand.
A practical map of where AI saves time or money on a client’s WordPress stack — with priorities, risks and a build estimate.
A working agent or automation wired into WordPress — lead qualification, editorial drafts, support triage or ops handoffs.
Reserved hours to improve agents, add automations and handle the AI tickets your clients keep opening.
Anonymised under NDA. Sector, scale and outcome only — names stay off the site unless the agency asks otherwise.
An 8-person agency had sold three WordPress projects into the same quarter. I took Figma-to-WP delivery under their brand, weekly demos to their PM, zero client contact.
Inherited a fragile WooCommerce store from a vanished freelancer. Root-cause fixes, caching and CWV work so the agency could hand a stable site back to their client.

“We stopped treating overflow as a hiring problem. Anton slots into our board, ships under our brand, and our clients never know there was an external engineer.”

The point of an external developer is to reduce your risk, not add to it. Everything below is built around protecting your deadlines, your standards and your client relationship.
Ten-plus years focused on WordPress: performance, technical SEO, custom plugins and WooCommerce. You get judgement, not just hours.
Clear updates at the cadence your project manager wants, and a straight answer when something needs a decision. No chasing, no surprises.
Estimates based on the work actually required, and a heads-up before anything moves the number — not an invoice that explains it afterwards.
Work delivered so your team can own it: readable code, a walkthrough where it helps, and notes that mean you're never dependent on me to keep going.
I've worked as the external engineer inside agency and product teams for years — your board, your repo conventions, your review process, your tools.
White-label by default. I protect the relationship you've built and never route around you — the credit, and the account, stay with your agency.
White-label by default. Most agency work never shows my name. Your client relationship stays yours — NDA and subcontractor agreement on request.
Work white-labelAgencies don’t lose clients on a missing plugin. They lose them on missed deadlines, silent freelancers and handovers nobody can maintain.
Fine for a one-off banner. Risky as delivery capacity.
Senior capacity designed for agency risk.
Four straightforward ways to engage, from a single fix to a full build. Every one starts with a clear scope, so you always know what you're getting and what it costs.
A single, contained problem
A specific bug, a broken component, or a small change your team doesn't have time to pick up.
A defined chunk, to a deadline
A scoped piece of work — a set of Figma pages, a feature, a WooCommerce build — delivered in a focused block.
Reserved, ongoing time
A block of development time held for your team each month, prioritised by you across whatever's live.
End to end, under your brand
An entire WordPress or WooCommerce site taken from design to launch, built, tested and handed over.
These are starting points. Final pricing depends on scope, complexity, timeline and technical requirements — you'll get a specific number before any work begins, not an open-ended rate.
Send me the project or the technical issue — a brief, a Figma link, a repo, or just a description of what's stuck.
I come back with a clear scope, an estimate and my availability, plus any questions that affect the number before it's fixed.
Work happens on staging with progress updates at the cadence your project manager wants. No black boxes, no radio silence.
Tested, documented and handed to your team — ready to present to your client as your agency's work.
Yes. Most of the agency work I do is white-label. I stay behind your brand, and I'm happy to be introduced as part of your team or to work entirely without client contact. Your relationship with your client stays yours.
Yes. I've worked as the external engineer alongside in-house teams for years. I fit into your process — a shared board, your repository conventions, your review flow, a standup if you want me there — and I communicate at the level of detail your project manager needs.
Yes. Taking over stalled or inherited builds is a common request. I start with a short review of the current state and the risks, then give you an honest assessment of what it takes to stabilise it before you commit to anything larger.
Yes. I build WordPress and WooCommerce sites from Figma with close attention to spacing, typography and responsive behaviour, so the result matches what your designers intended rather than an approximation of it.
Yes. Monthly development capacity reserves a block of time each month that your team prioritises, which suits agencies with steady overflow or clients on retainer. It runs month to month, with no long lock-in.
Yes. I build and stabilise WooCommerce stores — custom functionality, checkout and integrations — and handle performance on catalogues large enough that speed starts to affect sales.
You share the project or issue, I ask a few clarifying questions, then I come back with a scope, an estimate and my availability. Estimates are based on the work actually required, and I flag anything that could change the number before it does.
Yes to both. I'm based in Barcelona on CET and work with agencies remotely across time zones. An NDA or your standard subcontractor agreement is no problem, on request.
Yes. I work inside your tools and cadence — Slack/Teams, Linear, Asana, Jira, Notion, GitHub/GitLab. You set the channel and the update rhythm; I adapt to it.
I flag it as soon as it appears, with the impact on timeline and budget, before the work continues. No silent overruns and no surprise invoice at the end.
Yes. I operate as an autónomo in Spain and can invoice EU agencies with the correct VAT treatment. Say if you need a specific format or PO reference on the invoice.
Both. WordPress is the platform many of your clients already run; AI agents, RAG and n8n/Make workflows are how we make that platform do real work. Packages above are designed so you can resell them under your brand.
Send a short note, a Figma link or a repo. I’ll reply with whether I can take it on, a rough scope and estimate, and when I could start — usually within one business day.
