Following Land Securities Group's (one of the FTSE100 corporations and the world’s third largest real estate investment trust) acquisition of SMIF in February 2007, and after the successful integration with the new company's ICT infrastructure, my main responsibility is to maintain and further develop the specialized PPP/PFI management information system I single-handedly created for SMIF (main focus: business intelligence). Apart from the virtualisation platform (VMware) I used as a foundation for the load-balancing cluster with fail-over capabilities to host the system, all technologies employed by me to build the system are Open Source. For example:
- Debian GNU/Linux operating system
- Python programming language
- ZODB (Zope Object Database) and ZEO (Zope Enterprise Objects) ZODB storage implementation
- Zope (Z Object Publishing Environment) application server
- Apache web server
