Enzyme needed a freelance full stack developer with PHP and JS capabilities for refactoring and some new features for a turns system to control waiting time in the drugstore line.
The new features made development from standalone to multiple totems. One totem server serves one turn number, a client wants that all totems work together in a server-server with a master-slave architecture with auto promotion and restore capabilities.
Hardware architecture also includes a Big TV working as a monitor for ADs and ticket dispenser. The product needs a redesign and solves some bugs with code refactor.
