Profile bio

About Joran Kapteijns

Mobile and full stack web developer with over fifteen years of experience in developing user-friendly software for touch and internet. My focus is on the end user, not the means. That can mean I develop mobile apps, but also responsive web applications that work well no matter the size of your screen. And there is a lot of space between those two: for instance, a mobile app and website that share its core or an API but each have their own specific expansions.Some of the techniques I worked with last year, and enjoy working with: Java, Objective-C/Swift, Ruby on Rails, Unity (Augmented Reality), React, React Native, NodeJS, Bluetooth (Connected Devices / IoT).A few things that attract me to a project: the ability to work with new techniques or interesting products, connecting software to the real world, the ability to work together in an international team with fresh perspectives. Do you have something interesting for me, or are you interested in my profile? I'm looking forward to hearing from you.

Listed skills include Web Development, Mobile Applications, Software Engineering, Iphone Application Development, and 12 others.

When I started out in the world of mobile development, I also started my own company where I developed apps for many small and medium enterprises and charities. I often used different companies or freelancers for additional tasks, but I loved being the central point for each product and negotiating directly with customers about functionality. After five years, I switched my focus to more project-oriented work, but I still love some of the products developed back then.

Due to a company restructuring the frontend development was going to move to a department in Portugal near the end of 2018.I joined the team to take over, expand and document the existing project. Then I advised on the requirements for moving the projects to the Portuguese department. I helped set up the department, select and prepare my new teammates. After a short onsite onboarding, we continued to collaborate remotely for almost a year to expand and grow the department in Portugal until all work was handed over.The development has now moved successfully to Portugal. I am still occasionally advising on an ad-hoc basis as a consultant. Show less

Consultant Developer

Arnhem

The first version of Allego's mobile charging app, Smoov, had a lot of issues and not fully working parts. This resulted in a lot of costumer dissatisfaction, which was reflected by an average rating of 1.8 in the Google Play and Apple App Stores.We rebuilt Smoov from the ground up. By integrating the new version more directly into the IT landscape and working with a dedicated team, we were able to release a new version that averages 4.0 on both app stores.

Development and support of several mobile applications, web interfaces and connected device bridges for Philips Research, in fields ranging from rapid prototyping via small-scale consumer-oriented to certified medical products.
