HiFi Wiki eBay is one of the most interesting projects I have worked on. Unfortunately it has never been finished.
Information on this site was downloaded from Wiki, HiFi equipment website. The plan for the site was to target German speaking internet users, roughly 100 million users. The idea was to monetize the site through German eBay platform in the first phase, which was actually realized, and later through Amazon or some other equipment supplier.
I was entirely responsible for planning and designing the site. Before the project was stopped, all that was left to do was to process and adapt the data downloaded from Wiki site or, more likely to download it again, this time under my supervision, and then do some fine tuning.
