Hi folks,
Meet StaticPages, a great new platform to operate Jekyll-powered blogs, publications, company pages, marketing landing pages and whatnot. This landing page for the platform itself has been made using Jekyll (3.5.0) and a free Coming Soon theme (slightly customized) by Revolthemes.
Converting HTML-only theme pages into Markdown were nothing but pure fun - it took me some includes, data files to keep repeated blocks (features and credits) under control. The rest was quite straightforward, split into pages and sections - easy and quick.
In addition to that I rolled out a customized flavor of Puma web server + Google Firebase to deliver lightning-fast R.S.V.P (or Subscribe) end-user experience that allows keep customers data private, sounds & safe while serving pages over free SSL certificate by LetsEncrypt.
To make it sound even cooler, the landing page actually runs inside a Docker container 
and yields quite impressive performance metrics.
To make it run I used quite a few of open-source projects and hand-written backend code. 
Hope you will like it and your feedback as always is much appreciated!
Cheers! 
Pavel
