We should collaborate! I've also been building a job board but for the north american market mostly. I have an engine that scrapes and organizes job listings automatically. I haven't worked on it in months but it's still going strong scraping and archiving. It also has a backend to subscribe, apply, save, sort listings & companies etc, has a few minor things to finish up otherwise it fully works. Let me know how to contact you if you wanna chat. I haven't quite had the motivation to launch/do anything with it.
