- VPN (openVPM)
- Firewalls (ALIX, pfSense, hardware, proxy)
- Networking (Managed Switches, vlans, dhcp, DNS)
- recabled multiple racks to reduce complexity & simplify diagnostics
- Antenna design
- Overlapping networks
Previously to support clients there were a mix of different servers & different support technologies, controlled via a complex set of Shell Scripts which was only available to administrators. This was solved by streamlining all the different technologies in to one simple OpenVPN server based on common hardware with pfSense, with a simple graphically appealing interface for all staff to use from anywhere. This also opened up the ability for staff to work remotely, with the added benefit of drastically reduced technical issues & calls.
A second version was developed but never released, written from scratch in Dojo with mobile in mind. This had a few advantages:
- More efficient in regards to loading speeds, as it only loads what it needs at any one time rather than everything.
- Mobile-friendly interface, for technicians in the field to get instant feedback on the systems they are working on.
- More informative at a glance with data arranged more logical to the workflow of support staff
I was brought in to design, build and support a new Digital Media System that was to replace an ageing and extremely buggy PERL system (iDesign) that was currently in use. FlexiFi was the outcome, written in PHP to be a more solid, supported and easily extendable duplicate of the original system yet with many features implemented that had previously been impossible.
This was successfully sold and deployed to over 100 sites nationwide (200+ systems) which required a custom Intranet development and VPN to keep track of it all.
Each system was a dedicated PC with a highly customised Linux distribution, which contained its own LAMP stack with built in CMS. This allowed it to be updated both remotely by support staff & locally by clients themselves.
The systems themselves were able to display slideshows consisting of customised text, graphics and videos, along with menus that could accommodate multiple prices – all of which could be scheduled.
It was a highly successful product which was replaced a few years later by the far more advanced FlexiFi2 product.
