You have an idea.
I build it.
For founders and operators who want agency-grade work without agency invoices.
13+ years freelance · European clients · Zero downtime.
Our previous builder went silent after launch. Nobody picks up.
We want to move forward — but every quote starts at six figures.
I want one number I can call when something breaks.
I get it. That's why I work this way.#PaulDeZwaan
Where founders usually get stuck.
You have an idea, not a tech team.
You want quality, not a quick fix.
You want a partner, not a vendor.
You don't want to know what a server is.
Servers, deployment, SSL, backups, mail — I take care of all of it. You focus on your business.
Not just for clients. For myself too.
Four products I built and run myself. Concept, code, servers — all of it.
Four products · Four servers · One person.
Who I work for — past and present.
One partner, whole stack.
From first sketch to running server. Concept, design, code, deployment, hosting, maintenance — all by one person who knows your product end-to-end. No handoffs, no noise, no "you'll have to ask someone else".
Concept & Design
From rough idea to working concept. I think in complete systems for founders who have the vision but not the technical language.
- Concept to execution
- MVP blueprints
- Process optimization
- AI strategy
- Vibe Coding course
Development
Building the software itself. Frontend, backend, AI agents, content engines — whatever the job needs, with the right tool.
- Web & app development
- AI automation & agents
- Content engine
- Social automation
- Publisher sites
- Linkbuilding & SEO
Infrastructure & Maintenance
What runs under the hood. Servers, deployment, monitoring, backups, mail. You focus on your business — I keep it running.
- Server setup & DevOps
- Deployment & CI/CD
- SSL & domains
- Backups & monitoring
- Mail servers
- Long-term maintenance
Paul helped develop several projects with great results. He is hard working, keeps his promises and is knowledgeable.

One point of contact for everything technical.
What clients asked for → what I built.
Five real briefs. A one-line ask on the left, the shipped product on the right.
I'd like a coaching platform for innovation.
A multi-tenant SaaS with cohort flows, modular learning tracks, AI feedback on every assignment, real-time progress dashboards and Stripe subscriptions — white-label-ready for each new partner.
I'd like an automated customer-support system.
An AI agent with RAG over your own knowledge base. Tickets from email, chat and WhatsApp converge, get auto-classified, draft a reply, and escalate to a human only when it really matters — 70%+ resolved on first touch.
I'd like an automated content system for Google — with quality checks built in.
ContentBeast: a YMYL-grade pipeline with E-E-A-T checks, source grounding, schema injection and an editorial review layer. Auto-publishes to Laravel, a Shopify plugin and WordPress — fills 100+ websites with content automatically in a single day, without ranking drop.
I'd like webshop software for digital products.
A headless commerce stack with instant license delivery, Stripe + Mollie + iDEAL, subscriptions, affiliate tracking and a Cloudflare CDN for downloads. Refunds, churn and LTV are built right into the operator dashboard.
I'd like a platform like Thuisbezorgd.
A fully custom-built WordPress platform with WooCommerce-like functionality: restaurant onboarding, live order flow, courier routing and payments. No off-the-shelf plugin — the entire ordering flow is custom code shaped around their process.
"I want a platform for advertisers and publishers with pay-per-click payouts."
A custom ad-tech platform with strict fraud detection (click-pattern analysis, IP and device fingerprinting, bot filtering, hold-back periods) and per-campaign stats — clean payouts to publishers, protected ad-spend for advertisers.
Built in-house. Battle-tested on our own clients.
High-quality, fact-checked, source-cited articles at scale.
Multi-channel pipelines that generate, schedule and analyze.
All-in-one: sessions, payments, content, community, email.
Niche publishers we build, rank and monetize ourselves.
AI is how I deliver team output, solo.
No marketing-AI. No ChatGPT wrapper. I use AI as a production tool — Claude, agents, automation — to ship faster at the same quality. You pay for one developer, you get the pace of a small team.
The right tool for the job, not one religion.
Hand the whole concept to one operator.
Server, code, content, ranking, launch — all under one roof.
