Jacqueline de Gruyter - Consultant

For the past 10 years Jacqueline de Gruyter has been immersed in the world of mobile apps. As the founder and programmer of the Appril festival she built connections between the crème de la crème of the Dutch app scene. She invited inspiring speakers to talk about all aspects of realizing an app: from idea, design and coding, to the final launch. With her work, she inspires technical and non-technical experts and stimulates innovation.

Starting from 2019, she and her festival partner have been working on both the App festival Appril and Appdevcon. Appdevcon is an event for app developers where software development is the central focus.

Jacqueline’s work is about inspiring, connecting and growing as an professional. From developing a training course, a soft skill training, app festival programming or resumé improvement. Good craftsmanship and new, innovative ideas motivate her. Whether it's the design of a wooden chair, a painting or a technical solution.

The last few years Jacqueline has focused on supporting app professionals with finding new jobs or projects. She organised a ‘soft skills’ program for app developers, focused on developing additional skills important in furthering any career. She has also been active in creating podcasts with the app community and committing her time to Appsterdam finding new partnerships.

Maike Warner - Recruiter

After years being in the art field, Maike has used technology to design and create projects. The ease in which she adapted new tools and methods came in handy when she decided to learn iOS development to build an app she saw missing in the marketplace. 

This led to learning many distinctions around programming, version control, frontend, UI and UX Design. Maike spent many Saturdays in the Appsterdam MeetUp as a newbie, to leading it, which she continues to this day. It was in Appsterdam that Maike connected with and developed mad respect for developers.  She loves to be with them, whether it be to talk tech or life.  

It is her great joy to be able to support passionate developers in getting great projects and jobs. Hit me up over at and let's connect!
