I architect and build high-performance WordPress sites, technical SEO optimization & AI-powered automation.
Bespoke themes on an architecture that scales — headless when it makes sense.
Plugins built from scratch and wired into the systems your business already runs on.
Where WordPress stops being a website and starts doing work.
SEO engineering, not marketing SEO.
Fast under load, and hard to break.
Not just keeping the lights on.
Median PageSpeed score across the sites I've delivered.
Average speed-up after a rebuild — from 4.8s to 2.0s load time.
On WordPress — 60+ sites shipped and maintained.
Average organic traffic lift within six months of launch.
Uptime maintained across every site on a care plan, with monitoring and hardening baked in.
Every sector leaks conversions somewhere different. I find where yours leaks, then engineer the fix.

From catalogue to checkout — fewer steps, faster pages, more completed orders.

Anton migrated our ten-year-old site with zero downtime. Core Web Vitals went from 45 to 98.
Best WordPress developer I've worked with. The technical SEO depth is unusual for a developer.
Our WooCommerce store handles ten times the traffic it used to. The performance work paid for itself in a quarter.
Fixed an indexation problem we'd been chasing for a year. Our category pages finally rank.
He rebuilt our checkout and cart abandonment dropped by a third. A plan and weekly demos, no drama.
The AI pipeline drafts our product pages. Two days of work became twenty minutes.
We passed our accessibility audit on the first attempt. He treats compliance as engineering, not a checkbox.
Hacked twice in one year before he took over. Since the hardening and WAF work, eighteen months clean.

Deep dive into your WordPress setup, performance metrics, SEO health, and security posture. You get a detailed report with prioritized recommendations.

Deployment checklist, DNS migration support, and post-launch monitoring. 30-day warranty on all work plus optional ongoing care plans.
Ready to start? Most projects begin within 48 hours of agreement.
Schedule discovery callI am not a studio with a sales layer. You hire one senior engineer who scopes the work, writes the code, and carries the consequences — the same person, from the first call to the third year of maintenance.
One person, senior from day one, accountable end to end.
A pitch team, a delivery team, and a gap between them.
Flexible support for smaller projects
Best value for growing businesses
Maximum value for dedicated support
Whatever you need. WordPress development, custom themes & plugins, technical SEO, performance optimization, AI integration, migrations, troubleshooting — you set the priorities, I deliver the work. No pre-packaged features, just results.
Month-to-month contracts. Cancel anytime. Unused hours roll over within the same month.

My comprehensive approach means you're never left dealing with critical issues alone — I'm your long-term technical partner, ensuring uptime, security, and continuous improvement.

Both. Most of my work is on existing WordPress sites — audits, rebuilds, performance and SEO fixes, migrations. New builds are welcome too.
Within one business day on CET hours, usually much sooner. Active projects get same-day replies on the agreed channel.
Yes. Site down, hacked, or broken after an update — send the details and I'll prioritize it ahead of scheduled work.
Yes. I work with whatever you already run — shared, VPS, managed WordPress, or cloud — and recommend a move only when it's the actual bottleneck.
I'll say so upfront and point you to someone I trust, or coordinate with your existing team so nothing falls between the cracks.
Yes. I sign NDAs and work under a written agreement covering scope, rates, IP ownership, and confidentiality before any access is granted.

They roll over within the same month, so a quiet week isn't lost. They don't carry across months.
