At TSA I designed and implemented an interactive real-time multi-threaded server for relaying large volumes of stock market and news data in multiple formats including Reuters Market Feed. This server sits on top of a template-meta-programming library I wrote for parsing, and generating the bespoke messaging format. I also maintain the previous release. At TSA I also converted many software libraries to the cmake build system. I also wrote an adapter to allow Boost ASIO to be used with an interface identical to Tibco Rendezvous and a library for expressing configuration files in lua code. Technologies used include:

• Boost (including boost ASIO).
• Tibco Rendezvous IO.
• Reuters RFA.
• C++, with template meta-programming and expression templates.
• Linux & Solaris 8, 9 and 10 (x86 and Sparc).
• Cmake 2.6-8, gnu make.
• Lua 5.1.
• Gnu AWK, nawk, perl and C.
• OpenSSL.

I moved to Singapore to work for Mavenlab, a small company who write rich and interactive "web 2.0" websites and work on various mobile platforms. Here I worked as a system administrator, designer and programmer. At Mavenlab I designed and developed software in a variety of languages including Ruby, Java, C++ and unix shell. The tasks I performed included:

• Developing several high profile interactive websites from scratch both alone and in small teams.
• Writing widgets for websites in DHTML with JSP backends.
• Installing new hardware in a data centre.
• Administered a small network of machines running Gentoo, RedHat, CentOS, Ubuntu and Mac OS X.
• TCP/IP networking and installing and maintaining iptables firewalls.
• Writing a large set of zsh scripts to allow complex system administration tasks to be performed by laymen from the command line or using a web interface.

At Yahoo! I was part of a team that provides location services, which includes determining where a user is, or whether they are searching for a location amongst other location related services. Here I have:

• Designed and implemented a high performance multi-threaded webserver in C++ using Boost and the STL that provides traditional webserver technologies such as CGI and serving static data, amongst more advanced concepts such as accessing shared resources. The webserver is built from the ground up to support Web 2.0 technologies such as AJAX and Comet.
• Implemented some web services with the webserver I designed.

Amadeus are a leading provider of software to the airline industry. I worked as a C++ developer on a large multi-tier, multi-threaded real time check in system. My tasks at Amadeus included:

• The entire re-design and implementation of the customer check-in server using advanced C++ techniques (policy-based class design, iterator adapters, template meta-programming).
• The design and coding of STL extensions for use throughout the company.
• The design and implementation of a regression system built on top of the existing Perl coded test system. This system simplified the implementation of the regression building process and vastly increased maintainability.
• The design and implementation in python, of a system allowing object code to be stored and referenced against CVS releases of the code, and then re-used via symlinks to shorten compilation time for all developers considerably.

I carried out a 6 month internship at MIK which was part of my course at Imperial. At MIK I worked in a mainly Windows based environment, which allowed me to broaden my skills and experience which had previously been heavily Unix based. Here I gained experience and worked in the following areas:

• OLAP (multi dimensional database systems).
• A JSP 2.0 website (using CSS, XHTML, XSLT) to aid human resource management.
• Visual Basic programming (maintenance and development). Visual Basic tasks included programming an add-in to the Visual Basic IDE to allow full CVS integration from the UI.
• Visual Basic for Applications. This involved programming with Microsoft VBA using mainly Excel and Access, but also included VBA programming for Powerpoint.
• C programming.
• PHP/MSSQL website development and maintenance.

Elefire core services are the administration and management of firewalls and intrusion detection systems. They specialise in providing open source solutions. Here my roles included:

• C/C++/Perl/PHP development, maintenance and debugging.
• Maintaining the installation of and creating plug-ins for an HTTP based real time service monitoring system.
• Linux daemon programming (Perl/C/bash) and the SySV runlevel system.
• Creating a version of RedHat Linux 7.3 which would run entirely from CD and ramdisks. This involved modifications to the RedHat Linux code, and insertion of my own shell scripts to detect hardware/graphics card settings etc. It also involved writing C code to run from a custom ramdisk which I also created, to allow the CD-ROM drive to be detected and for Linux to be booted from the CD-ROM in this drive.
• Installing and testing Linux programs on the internal network.

The job also offered me the chance to gain experience with high availability systems (running RedHat Linux 7.3 and 8.0).

At Astraguard I was part of a small team whose aim was to port a previously Windows based system over to Linux. My roles included:

• Setting up a custom Linux distribution to be installed on a number of machines running specialised video grabbing software and hardware.
• Graphical user interface programming (Perl/Tk).
• PHP web-pages to manipulate extensive XML configuration files (to allow remote configuration via a browser).
• Programming a console program (in C++ using NCurses) to monitor and adjust the operation of the software.
• The design of parts of the company website (XHTML).
• Shell scripting (to automate the task of installing 45 machines running specialised software).
• Installing a software RAID.
• Maintenance of a network of machines running Linux and Windows 98/2000.

Follow up support was then provided to the company over the following months after my period of work, which involved fixing bugs and adding additional features to the software which I had designed.
