I turn complex problems into scalable software. At Free Amigos I work with clients on tech strategy and architecture, often combined with hands-on technical execution.
With Coach Amigo I help 50,000+ coaches manage matches, line-ups and stats. I also build custom WordPress plugins, such as Manage Notification E-mails: used on 100K+ sites, with toggle control over core WordPress notifications, multisite support and import/export.
AI is part of how I build: in the products themselves, with AI agents and retrieval-augmented generation, and in how I design, write and ship software every day.
AI Activated
Senior engineering
Adding a chatbot is easy. Making AI reliable, affordable and safe inside a real product takes architecture. I bring years of senior engineering to work: clear data flows, guardrails and systems that keep working after the demo.
AI
AI agents
Agents that take real actions in your product and processes, with well-defined tools, clear boundaries and human oversight where it matters.
AI
RAG & your own knowledge
Retrieval-augmented generation that answers from your own data and documents. That means grounded answers instead of guesses, built on a solid data architecture.
AI
AI architecture & strategy
Choosing models, structuring data, controlling cost and protecting privacy. I advise on where AI adds value and design how it fits into your existing systems.
AI
AI in production
From prototype to production: testing and evaluating AI output, handling edge cases and failures, and monitoring the result so quality stays high.
AI
AI-accelerated delivery
I use AI coding tools daily to design, build and review software faster, with the senior judgement to know what to keep and what to reject.

Projects
A selection of recent work, from multilingual brand platforms to AI-powered apps and open-source software.
A WordPress plugin that applies rules to every outgoing email: redirect, add recipients, rewrite, hold or block, based on conditions such as which plugin sent it. The Pro version adds AI email routing: the AI reads each email, assigns an email type and routes it, for example spam to quarantine and sales questions to the sales team.
AI skills — teach the AI the terms, product codes, suppliers and customers of your own business.
Learning period — the plugin observes the site’s email and suggests rules with AI.
Privacy by design — only subject and body go to the AI, never recipients or sender; addresses, phone numbers, links and codes are masked first.
Built on WordPress Connectors — works with the AI provider you connect in WordPress 7.0+.
Ongoing development of online projects and sites, plus technical advice. A central WordPress solution feeds the various De Kuyper sites in multiple languages with products, shop information and descriptions.
A digital ‘walking survey’ for researching the qualities of residential neighbourhoods. Web and mobile environment with a full WordPress back-end for setting up and maintaining surveys.
Development for Qidos on the initiative by CNV, the Dutch Ministry of Health (VWS) and the Hersenstichting promoting an inclusive workplace with equal opportunities for everyone.
