Collaboration & Projects
What kind of companies do you typically work with?
I work with a wide range of organizations, including startups, corporates, and government agencies. While I am highly adaptable to different environments, I work best with teams that are curious to see the potential of data-driven solutions and value a pragmatic, results-oriented approach. If your organization embraces innovation and encourages streamlined decision-making processes, we will highly likely be a great match!
How do you approach a new project?
I begin every project by gaining a deep understanding of my client's unique needs and goals. Using a design thinking approach, I translate business challenges into practical, data-driven solutions. Collaboration is key - I aim to keep clients engaged and informed throughout the entire process, ensuring that the final outcome aligns with their vision and delivers real impact.
Do you also provide consulting or strategy advice?
Most certainly! I help companies define and fine-tune their data-driven strategies, ensuring they align with business goals. This includes developing actionable roadmaps and concrete steps for implementation, guiding teams through the process to ensure success. Whether you're setting up a new strategy or optimizing an existing one, I can provide the expertise and direction needed to help you achieve your objectives.
How long would you typically work on a project?
My ideal timeline for a project would be 3 to 9 months. This allows me to dive deep into the work while keeping the environment fresh and dynamic, at the same time providing enough time to deliver meaningful, long-lasting results. That said, I am also definitely open to longer- or shorter-term projects if that better fits your needs.
Pricing & Contracts
What are your rates?
I offer hourly, daily, and full-project pricing based on the market rates that are typical for The Netherlands / North-West Europe. The final rate depends on the specific scope of the project.
Do you offer fixed-price projects or only time-based billing?
My preferred billing model is time-based, since this is easiest to keep track of and report on. However, fixed pricing models for projects are also possible, as long as an expected timeline and periodic installments are agreed upon.
What are the payment terms?
This depends on the project and the size and financial situation of the client company. For longer projects with larger, established, stable companies I would prefer to e.g. bill monthly with a payment term of a certain number of days (generally around 30). For smaller and / or less stable companies, we could combine an up-front installment with e.g. periodic billing. If no custom terms apply, see the General Terms of Data Ilumina.

My core tech stack is focused around Python, SQL, Databricks, Machine Learning, Azure, Amazon Web Services (AWS), Data Science, Data Analysis and Data Visualization. See the Tech Stack in my Skills section for a more comprehensive overview.

In many cases: yes! I strive to adapt to existing infrastructures and work with a variety of tools, platforms, and frameworks. If you are unsure whether your tech stack is a good fit, feel free to reach out - we can discuss the details and find the best approach for your needs.
How do you ensure data security and compliance?
I take data security and compliance seriously. I follow best practices for handling sensitive data and adhere to relevant regulations, such as GDPR or the AI Act. If your project has specific security or compliance requirements, I am happy to discuss them to ensure everything aligns with industry standards.
