Johan den Haan’s Experience

Head Research & Development

Mendix

(Privately Held; Computer Software industry)

August 2007 — Present (2 years 4 months)

Responsible for the whole Mendix technology stack, including:
- Mendix Business Modeler, a modeling studio focused on Domain-Specific Modeling with multiple integrated Domain-Specific Languages (DSL). All models (in different DSLs) are automatically checked for consistency, changes are propagated, etc.
- Mendix Runtime, a scalable service-oriented server component for interpreting the models.
- Mendix Client, web-based engine for presenting a GUI to end-users of the application.

In short: with our technology Service-Oriented Business Applications (SOBA) can be developed with use of high-level models.

In 2009 Mendix was recognized by Gartner as Cool Vendor in Application Development. Cool Vendor means: innovative, impactful, and intriguing.

My tasks involve:
- Leading and scheduling the very talented R&D team.
- Product / release management.
- Overall architecture.
- Methodology.
- Integration with other technology / products.
- Some programming to keep the feeling, i.e. design and implementation of parts of the runtime component. For example, model interpretation, service-component architecture, transaction management, etc.
