Looking for a developer with experience in game development

I am looking for a developer with proven experience in video game development specifically in browser based strategy or MMO style systems. The project requires full privacy and complete control over every module and all operational data. The interface must be modular and screen based inspired by static MMO strategy games from the 2000s with no animations and no dynamic transitions. The system must include battle logic resource management market mechanics and a UTC based PvP timer accurate to the second synchronized and reliable. The entire experience must run directly in the browser with compatibility for both Web2 and Web3 and no installation required. Additional information is available upon request. Images shown are for example only and the style names and story are different. Only developers who can provide real testable work will be considered. A playable demo is required before any collaboration. The demo can be an existing project a past work or a small technical sample and it does not need to be related to my game. This requirement exists to verify technical ability not to request free work. If you cannot provide a clean functional browser ready demo please do not apply.
