Dutch AI language expertise, AI training work and senior interim talent

Jazzer operates from Rotterdam, the Netherlands, across three distinct areas: native Dutch language evaluation for AI teams, a route into paid AI training work for language and domain experts, and senior interim or fractional professionals for companies with a defined need in Europe.

For Dutch AI work, Jamie de Graaf reviews model responses, prompts, translations, localisation and spoken Dutch for meaning, fluency, tone, register and cultural fit. Candidates and companies follow separate routes, so each page can focus on the requirements and next step that matter to them.

What do you need from Jazzer?

The three routes are deliberately separate. AI teams can work directly with Jamie on Dutch-language quality, candidates can explore paid AI training work, and companies can define a specific interim or fractional mandate in Europe.

1. For AI teams and data labs

Dutch language quality for AI

Need Dutch model output checked before release, during evaluation or after localisation? Jamie reviews responses, prompts, translations and spoken Dutch for accuracy, fluency, tone, register, cultural fit and consistency, with clear written feedback for the team.

3. For companies

Bring in senior interim expertise

Need a CFO, COO, CTO, transformation lead or another senior professional for a defined period or business problem? Start with the situation, decision rights, market and required start date. Jazzer uses that mandate to identify professionals with relevant European experience.

Based in Rotterdam

Independent, hands-on and built around specialist work

Jazzer is run by Jamie de Graaf from Rotterdam, the Netherlands. Since 2013, the business has worked across SEO, content, WordPress and online operations. That background now feeds directly into Dutch-language AI evaluation, where the difference between a correct answer and a genuinely good Dutch answer often comes down to meaning, register, tone, context and consistency.

The work is deliberately practical. For AI teams, that means reviewing actual output and explaining what is wrong and how it can be improved. For candidates, it means comparing a profile and CV with current published project requirements without promising selection, workload or pay. For companies, it means defining the business situation and senior responsibility before looking for the right experience.

Jazzer works internationally from Rotterdam. That context matters in practice: Dutch AI quality is often judged against English source material, translation workflows or localisation choices, while senior European mandates often sit between a local market and an international headquarters.

Tell Jazzer what needs to be reviewed or led

For Dutch AI language work, share the output, workflow or quality problem you need help with. For senior interim work, share the country, business situation, responsibility and timing. Candidates should use the AI training jobs route rather than the business contact form.
