About / AI engineer, Amsterdam
about me
I'm Andres, an AI engineer in Amsterdam. Getting an AI demo working is easy now; making it hold up in production is the hard part, and that's where I focus: evaluation and regression testing, cost control, observability, and security, from guardrails to prompt-injection defense. Right now that means Cabyn.ai at Boundless Digital, an AI-native SEO platform I took from a single-server MVP to multi-tenant AWS infrastructure as code.
With this blog I want to teach people how to build AI systems that are safe and reliable. These days a million influencers teach the same things: how to automate tasks, how to use Claude or ChatGPT, how to generate animations. Almost no one teaches the kind of engineering it takes to make a product work at production level, so that is what I write about. It is also a way to hold myself accountable to keep learning in my free time.
