·About / Profile

Builds the full stack. Ships the AI.

I started as a frontend developer in 2017 and moved into backend a few years later. The stack runs wide: React, Next.js, Laravel, Node, Python, plus the infrastructure to actually run it in production. The AI work came after that. Multi-agent systems, RAG platforms, on-premise LLMs. It's the latest chapter, built on top of the foundation, not stacked next to it.

At Vloto B.V., I build the AI systems and the backend they run on. The customer-facing WhatsApp agent resolves over 55% of conversations autonomously. There's voice AI for inbound calls, fraud-prevention models, on-premise LLM workflows running quietly inside the company, plus the booking algorithms, internal dashboards, and APIs underneath. With Virelio, I bring the same full-stack-to-AI approach to other companies.

Best taught by doing.

I'm the lead AI engineer at Vloto. The work is half engineering, half teaching: showing the team how to automate their workflows with the techniques and internal tools I build to compress dev time.

Outside the company I run AI lessons and webinars. Same principle: the only way to teach AI is to build it in front of you. No slide decks.

Frontend & Backend Development
Software Developer · Amstelland College
Three years going deep on the fundamentals. The first half was frontend craft: HTML, CSS, and JavaScript until the browser felt like a familiar room. The second half flipped to backend: PHP, MySQL, and C#. Database schemas, CRUD operations, the unglamorous plumbing every real system runs on. The foundation everything else got stacked on top of.
