Senior Data & ML Platform Engineer | dutchengineer.substack.com | Host of Ask A Data Mentor Podcast

Built real-time ML systems delivering millions of daily inferences. Integrated LLMs that saved over 1,000 hours per week across the company. Designed scalable MLOps platforms that took model deployment from months to days.

I have spent the last 8+ years driving AI and ML engineering efforts across startups and high-growth companies. My work spans productionizing models, leading company-wide ML initiatives, and building systems that work. 

Highlights:
Led LLM integration at Equipmentshare, embedding OpenAI into internal tooling to save 1,080+ hours weekly
Deployed Zwift’s real-time racing score model, handling 8.6 million inferences per day
Cut ML deployment times from months to 3 days with standardized CI/CD and packaging
Rolled out Databricks company-wide, reducing deployment cycles by 4x
Built ML pipelines for pricing $3B+ in fleet assets, churn risk, and invoice automation

I write often on machine learning systems and infrastructure on dutchengineer.substack.com, and I enjoy helping teams ship fast, reliable ML in production.

Ted Talk about myself:

I distinguish myself by possessing great leadership qualities. In projects, I am often the team lead and strive to create a structured, calm, and pleasant working environment for my team by implementing the right processes and a great/safe culture.

As a motivated and highly experienced professional, I often take on the role of translator, facilitating communication between technical and non-technical folks. With strong communication skills and empathy, I excel at this, which my record shows.

I have initiated and/or delivered many challenging projects and have learned that building a highly skilled and fun team is essential to success. Throughout my 15-year career, I have demonstrated my passion for building and running such teams effectively.

I am committed to developing and nurturing talent. I take pride in mentoring and guiding colleagues, believing that investing in the growth and development of others is essential for an organisation’s continued success and my own growth.

Over the years, I’ve worked for a diverse array of clients, including Rabobank, Heineken, LELY, Albert Heijn, Eneco, ING, Ymere, Oasen, Vewin, European Commission, multiple Dutch Ministries, Wageningen UR, NZO, (Z)LTO, and Oxfam Novib.

Among my proudest achievements are managing all data science solutions for a company boasting $2.4 billion in revenue, organising a Dutch trade mission to Silicon Valley, and leading a project on sustainable crop cultivation for the largest Dutch supermarket.

My technical knowledge spans a spectrum of tools and technologies, including Python, R, SQL, bash, GitLab, GitHub, Azure DevOps, CI/CD, PyCharm, Jupyter, Databricks, RStudio, RServer, Sagemaker, Azure ML, Snowflake, MS SQL Server, SSIS, SSAS and PowerBI.

Working with US cloud services as a European organisation is no longer safe. We learnt over the past years that European data under GDPR Europe is still being accessed by US intelligence agencies.

I wanted to make a big fuss about this when in May 2025 the chief prosecutor of the International Criminal Court lost access to his MICROSOFT email address as a sanction by the US.

Moreover, his bank accounts were frozen.

Why? Because, you know, applying international criminal laws didn't sit well with the current US administration. At the time I felt like a looney for sounding the alarm. I abandoned my idea of writing a blog series about moving away from big tech.

Not anymore. 

Considering the current geopolitical tensions, don't be surprised if you can't acces your email, files or worse in the near future. Digital infrastructures are strategic and operational assets which we can't loose. Especially in critical industries.

Migrating or backing up to EU alternatives while we can is a necessity. Below are a few options, but there is more out there. Please extend the list if you can. 

This small list just shows that it's possible. Yes, the alternatives are viable. Yes, you will have to get used to a new UI, but is that really an argument? Don't believe the marketing  and PR lies. The EU can do tech too.

Principal Engineer | DX, Data, MLOps | Human writing | Creating the future’s technical debt, today

Data work requires tacit knowledge. The best data engineer is not always the most skilled one, but rather the one who understands the data and organisation best. 

Getting to know datasets takes time. Building good relationships with the business takes time. If someone in the team has been around for long and has these things... Treasure them! Try to keep them on. They are worth gold.

Even if they don't know the latest and greatest tech.

The practice of data engineering is getting drowned in tools. But the most important parts of the work are about data. Information. Knowing what is what. Knowing what is where. And about human relationships.

These things require experience. Veterans bring experience.

Want to come break production together? I can write some faulty Terraform and you can accidentally approve my PR. 
(No linting? No formatting? How did this get to main?!?)

If these are the question you ask, this role might be for you.

Feeling a little lost in all the AI coding craze of the last few weeks? This short blog, a great reflection on what's going on, offers remedy.

Written by Armin Ronacher it touches on:
- AI coding addiction
- syncopate driven soloing
- OSS struggles in this new era
- excessive token burning

https://lnkd.in/eg-9nrmg

Just a good and grounded read for any developer, whether you are into AI assisted coding or not.

Found through Matteo Renoldi.

Open article: Agent Psychosis: Are We Going Insane? by lucumr.pocoo.org

It is more important than ever to protect your data. Tech companies are eating it all. Evil regimes are on the rise. I was always a bit of a skeptical about this: "yeah whatever, they already know everything about us anyways."

This is not true though.

Data use and data rights are getting worse. We need to hold the line!

So what you can do?

- Review and limit app permissions on your phone
- Delete accounts you don't actively use
- Switch to a secure phone messenger
- Don't just connect all smart devices
- Use a password manager + 2FA
- Use alternative email services
- Use alternative cloud storage
- Use OSS where possible
- Use a VPN

‼️ ➡️ most important: move away from big tech 

And if you work in DATA and TECH educate yourself and pass the knowledge on to your family and friends.

I will repeat myself: We need to hold the line. Actions matter.

Any other tips to do so?

#data #privacy

AI assisted coding reached the point of good enough. We will see WAY more indie apps. But with that, we'll also see way more viruses, trojans, hacks, ransomware, etc. 

Tread carefully out there.

The excitement around "hey, check out my cool app that does for free, what that one SaaS tool charges you for" can come at a price. These unknown developers are:

- harder to hold legally accountable
- largely unversed in security practices
- not peer reviewed/starred in an OSS community
- not audited
- maybe not even real (hello fake profiles 👋🏽)

Even if the vibe devs mean no harm, they might have built something unintentionally wrecks your system. Ouch

Anyway...

I built this really cool app that does whisper coding really well 🤗
