Originating from my combined passion for aviation and mobile computing I have developed and released several aviation related iPhone applications, which, even though targeted
at a niche market, have proven quite successful

ZFactuur is an online invoice portal for the Dutch agriculture market. It forms the hub between invoice-senders, farmers, their accountants and the Notabox on-line payment system.
I was the lead software architect, in charge of all development activities,both in India and the Netherlands. ZFactuur is currently marketed in other sectors, most notably
the automotive sector and the construction sector.

CIS was developed for Rabobank International. It is a system aimed at providing compliance officers world wide an instant overview of their compliance risk status. It provides
easy reporting facilities, facilitates variations in rules and regulations around the globe and facilitates tracking of action plans that mitigate the compliance risk. It is now in use
with all Rabobank International Branches. I was responsible for drafting the system requirements, functional design and technical design as well as the development project lead.

In 2002 I founded Proxy Systems Pvt. Ltd. This company provides software development services for my clients, primarily in the Dutch Market.
The company currently has 15 full time staff.

iPhone airport series
A generic application for tracking flights to and from any given airport. Users can search for the flight they want to track,and the system will provide them "push messages" whenever
the state of their selected flight changes. Flight information is extracted from the targeted airport website. Due to the generic nature of this track tool it is easy to add new airports.
Currently Schiphol (Amserdam), London airports, Sydney, Dubai, and Hong Kong can be found on the App Store.
(Note:The Schiphol airport application is currently ranked #3 in the travel section on the Dutch App store)
Key technologies: Apple Push Message service, Xcode, Mule 2.2, Java 5, Regular expressions, JSON.

Development of NOTAMs
NOTAM stands for "Notice to airmen". Every pilot is required to read the notams that are applicable to his intended flight.As part of the Pre-Flight application I have developed a module that retrieves these notams and where possible present them on a map along with the intended route. I have converted this module into a separate application, which has proven extremely popular with pilots world-wide, most notably in the UK (especially since the recent ash-cloud events). I was responsible for the design, implementation and release of
this application on the App Store.
Key technologies: Objective C, Cocoa touch, Xcode, iPhone mapping, Core Data, HTML screen scraping, Regular expressions.
