Software development

I have a Bachelor of Engineering in Computer Science/Embedded systems. Since 2009 I've been specializing myself into Apple's iOS platform.

In 2010 I founded Logic Design. Ever since that point I'm doing contract work for business clients, mostly iOS related projects. For a selection of my work see the portfolio on the main page.

My recent expertise includes:

• Native iOS development: Xcode, Swift, Objective C
• Advice & involvement trough the whole process from idea to concept up until finished iOS app distributed to the App Store
• Consultancy on feasibility of iOS apps, Apple App Store requirements and App Store distribution as well as Enterprise/In House distribution
• Communicating with Apple on time critical App Store related matters
• External device/hardware interfaces and using the all available sensors on iOS devices
• Low level GNSS (GPS/Galileo) systems including Real Time Kinematics
• GPS tracking technologies in aviation

Flying

When I did my first flight on a glider in 2005, I instantly knew I wanted to do this myself. Ever since, I've enjoyed every step, from the thrill of flying solo for the first time, up to long cross-country flights and participating in gliding contests. With gliding, I have a strong affection with the possibility of always having a new challenge, have a new goal, continuously learn new things and raise the bar.

I really like to link this to my work profession. Trying to see things from a different angle. Don't fear to think out of the box and face new challenges.

What's gliding all about? Gliding is probably the most accessible way of learning how to fly. In my opinion it's also the purest form of flying. For example, lot's of experienced airline pilots still like to go gliding in their spare time. Heck, even astronaut Neil Armstrong concluded at the end of his life, that of all the forms of flying he enjoyed gliding the most!

When you want to fly a glider for longer time, you basically use rising air. These thermals are there, because the sun heats the earth which in result heats the air above it. When you go circle in this air you can stay aloft for hours. You can fly from thermal to thermal, covering huge distances. Basically, you're flying on solar energy!

"Once you have tasted flight, you will forever walk the earth with your eyes turned skyward, for there you have been, and there you will always long to return."
- Leonardo da Vinci

Sailing

Over the last few years I picked up sailing again, something I've learned in my childhood. I immediately got hooked. There are so many similarities with glider flying, but for me, sailing is also more relaxing and something I can do on my own at any moment.

I also enjoy learning all technical aspects of working on boats. After having renovated my first, am now working on my second small sailing yacht, while sailing on it during the summer of course!

I like sailing either solo, together, or with friends on my boat on the beautiful waters of Friesland.

iGlide & iPilot

iGlide and iPilot are moving map apps for Apple® iOS® devices. The apps offer many functions for beginners, for pilots starting their first steps flying cross country, and for pro pilots in competitions. It is clear, easy to use, and simple. iGlide & iPilot give overview, even in highly complicated situations, takes the load off the pilot and gives more time to monitor airspace.

Space Leap

Space Leap is a new startup that I'm building together with a great and passionate team. We're focussing on drone delivery, delivering urgent goods between logistics hubs, hospitals, disaster areas, remote locations.

Tizin Mobile

Since 2010 I've been working in a partnership with Tizin Mobile. Together we have been working on a wide range of projects. It included projects that are running live for customers right now, as well as building challenging proof of concepts, where I could fully use my expertise on the iOS platform.

Notable projects include:

• Guard Mandown | Employee security with alerting service
• MyOrder | Mobile payments, including parking and fuel payments
• MyOrder Sidekick | Customer loyalty reward system
• Socie | Mobile app for clubs and communities
• Athlon Brandstofprijs | Check the lowest fuel prices
• Bizztravel Sneeuwhoogte | Check the snow thickness in the most popular ski destinations
• DocBase | Document management system
• DUO Student | (Dienst Uitvoering Onderwijs) Checking student grant dates and information
• Slim betalen | Payment method including mobile app

Proof of concepts include:

• Research and technical implementation of secured methods for user identification in mobile payment systems
• Secured communication with external webservices
• Building a APNS Push-notification system that can be used in later apps
• Utilizing iOS multitasking on apps that control critical processes, including personal safety alarming apps
• Research on code distribution and integration methods for 3rd party apps
• Research on iOS GUI building for white label apps

GripTools.io

Working together with Friesland AV on GripTools.io resulted in great products!

Projects include:

• Development of a native iPhone app and a Mac OSX application to communicate with the mobile app in 2009
• Co-development on a native iPhone app for real-time motion capturing. Utilizing the gyro, accelerometer and compass sensors on modern iOS devices as a full inertial measurement unit
• Development of various motion capture systems for Windows & Mac. Related aspects like 3D simulation of various motion platforms (airplane, helicopter) and hardware interfacing
• Active in development of 3D-chromakey principle
• Work on efficient and effective real-time filtering methods
• Development of automated payment methods using Paypal IPN (Instant Payment Notification system)
• Development of a system for automatically generating PDF invoices

GliderTracking

Forming a team with two friends in 2009, we started GliderTracking with one goal: make our sport more visible.

Gliding is a wonderful sport, but very difficult to explain to family and friends. You can see gliders in competitions only during take off and after 5 hours the pilots return to the same airport as where they departed. Where are all the competition pilots? Do they have enough altitude to make it home? What are the average speeds? How far do they have to fly?

With the latest technology it is possible to track/follow all gliders (equipped with a Mode-S transponder) during a competition, which is exactly what GliderTracking does. Other tracking technologies like SPOT satellite trackers and cellular trackers are also supported (and combined) on GliderTracking.

The existing wish lasts to visualize the sport of gliding to the general public. Live tracking is very suitable to pursuit this goal. Public at home and on the competition site can follow the pilot, like you are in the middle of it. GliderTracking was launched as a beta tracking system in 2011 during the Dutch National Gliding Championships, held at airport Terlet.

Go to glidertracking.com learn everything about it!

Stay tuned, more info on this exciting project will be published soon!

GliderGame

Starting as an OpenGL 3D arcade-style gliding simulator on Windows in 2009:

GliderGame development has evolved to a 2D game the iOS platform in 2012. In 2014 it evolved to a 3D game using technologies released in iOS 8.0. Screenshot of the iPad version:

More news expected soon!
