Eurocontrol Maastricht, NL

Contract Software Engineer May '00-Jun '09

Hired to improve the automatic processing of flight plans coming from IFPS.

This was achieved by automating a variety of methods routinely used by

Flight Data Operators such as routing replacements, coordination point

forcing and flight level forcing within the flight server and also

providing offline tools for the continued refinement of such methods in

Visual Basic. This project raised the level of automatic treatment from

less than 40% to it's current level of approximately 85%.

Technical lead in a number of Linux based projects as follows:

Recording and Logging Infrastructure project, which was a timely remote

data transfer facility utilising SAN disk systems, sockets, Python/TkInter

and bash scripting.

Development a process monitoring application in Python/Tkinter on Linux.

Implementation of Operations room break planner tool with Python, Tkinter,

Oracle on Linux.

Replacement of flight server mainframe incident investigation tools with a

Python/disk based solution.

Development of a hardware monitoring system with RFID tags, Python data

upload scripts, Oracle database repository, Apache/Tomcat/ZK/Ajax front

end.

Development of a web-based message log investigation tool based on Oracle,

Apache/Tomcat, ZK & Java.
