I have run now since about 2 years 4 different Developer Job Boards, which are:
All of them run on the same server and instance using my own job board software, developers in Go (Golang), Vue with ArangoDB and Redis for Data, and Nsq as Message Queue.
With the recent growth of Rust Language and related Jobs, I decided on a weekend to start a
Job Board for Rust Developer Job ( rustjob.xyz )
Thanks to my mentioned Job Software the time needed from registering the Domain related to Rust Language to configure a new instance on the same environment was about 1.5 hours only.
