FirstLook™ as an Online Software Platform is developed on the web application framework known on Ruby on Rails, which was developed by David Heinemeier Hansson.
David made a presentation at Startup School in 2008 and although this is a full 11-years ago, there are many extremely valuable idea he shared.
The presentation is a full 30 minutes long, where the simplicity of though has always inspired me.
Do take time to have a listen. :)
