ERP-style facility-management system Radoslav Stankov started as a weekend side project while CTO at Product Hunt. Stack: Ruby on Rails, Tailwind CSS, ViewComponent, minimal JavaScript (Stimulus-ready), with extensive end-to-end tests because it's business software. Multi-language. Used throughout his wroclove.rb 2024 talk as the source of real component code (stats, filter form, page header, table). Stankov joked the goal was to 'rename the building to happy building'.
