I was tasked with developing solutions for specific customer situations/request. Additionally, I wrote or modified software used, for instance, in customer billing or in the collection of billable data.
The most interesting project was the network design for a rich media platform for a Dutch TV organisation. The solution was meant to scale from a single 2 Gbps uplink up to a redundant 20 Gbps uplink without major architectural changes. The proposal was based on Cisco switches/routers and F5 load balancers; a partial implementation was started about two months before I left Versatel.

This was done with two collegues.
Later on my responsibilities included proposing, designing and developing new applications based on business requirements.
Most development was done using Perl or Java with a PostgreSQL, MySQL or Oracle database. For good measure, a lot of shell scripting and some PHP work was thrown in.
