ayco. Let’s talk

Curiosity,
put to work.

I’m Ayco. I bring technology, data and human behavior together.
Then I turn those connections into things that work.

20+ years of building at the intersections.

The approach.
Beyond one discipline.

Not quite a tech person. Not just a data person. Always a people person.

My best work happens where those worlds meet.

Think in possibilities.

AI, RAG, LLMs, ZK tech. I connect emerging technology to practical problems, and move from “what if” to something we can actually use.

Change your mind.

Strong opinions. Stronger curiosity. I'll argue hard for an idea, then drop it the moment the evidence says otherwise.

Start with the person.

I design from the user backwards. Clarity, behaviour and a little delight. Because the cleverest solution means nothing if nobody wants to use it.

Selected work.
Ideas with impact.

Menzis

Move more.
Live healthier.

Leading a multidisciplinary team to turn a health app into a platform that helped people build healthier lives. Start-up energy. Corporate complexity. Tangible impact.

App of the Year nominee

From complex challenge to meaningful change

Build the foundation.

Migrated a white-label app to a fully owned native iOS and Android stack on Microsoft Azure. Integrated Databricks to make data-driven experimentation part of the platform.

Bring the disciplines together.

Connected data science, health science and marketing. Combined gamification with evidence-based design, reaching people in lower socio-economic groups while balancing governance, audits and compliance.

Measure what matters.

*The healthcare cost result comes from a difference-in-difference analysis (University of Groningen, 2024), as reported in my professional experience. The app was sunset in 2024 after Menzis shifted its focus back to core insurance services.

Good things.
Better together.
Make this clearer.

Give the headline more breathing room.

See the friction.
Ship the fix.

“That bit needs work” is a feeling. A coding agent needs a brief. I built Rochel to connect the two.

Click an element, explain what should change, and export a structured Markdown brief with the relevant page context. Your notes stay in your browser.

The experience.
Same curiosity.

From scrappy beginnings to regulated environments. I’m comfortable with complexity, and happiest when we’re moving forward.

Deep in the work

Going deep on AI, RAG, LLMs, MCP and rapid prototyping within InsurTech.

Interim

Fast impact across growth, data, UX and innovation. Finding the signal, building momentum and making things happen in high-paced environments.

Start-up

Adapt, experiment, fail, iterate. The best way to learn is to build. Still building at MyAlbum.com.

Agency

Different industries, different audiences. A sharp sense of what works, when it works and who it works for.

Corporate

Innovation within the real world of governance and compliance. Comfortable navigating complex InsurTech environments without losing the drive to make progress.

Education

An MSc, and a statistical model that made it out of the thesis. Two algorithms: predicted visitor value, and conversion probability for every visitor. A way to take on the attribution problem and allocate budget on something better than gut feel.

The human.
Not always serious.

Deep in one thing, curious about ten more. A problem looks different depending on where you stand, so I try to stand somewhere else now and then.

Say something confidently enough and the room nods along. I'm the one asking why. Conviction isn't an argument. Mine included.

Probably not your person if you want a yes-person.
Definitely your person if you want to make it better.
