RPG by chat - code improvement and implementations

Purpose and area of ​​the project Role play game by chat (RPG by chat); not commercial and not for profit, entirely financed by the owner of the site and the domain (Altervista) on which the game will be loaded. Technical request I am looking for a programmer who can work on other people's material, fix the bugs on the given structure, put it in security, implement all the required features, mount the graphics that will be provided and load the site on the domain; would be appreciated a previous knowledge of the open source package (GDRCD 5.4.1 by Breaker) provided attached to this message. Mathematical skills are required to calculate the balance of certain factors and key scores in the game mechanics All the required functions and the printouts of the graphics to be mounted are present in the attached PDF files (in Italian and in English). You will be allowed to work on your own proprietary code / development of a proprietary code from scratch if required for reasons of time / convenience, as long as this does not impact the budget or does so only relatively. In no case will be considered to pay for the analysis of the code provided before you can get a quote. Expiration date The work must be completed in three months; longer periods of time may be taken into consideration only if duly motivated by technical and developmental reasons. Functionality management at the end of the work It must be possible to manage the entire platform through panels inside it, in order to facilitate ownership of the site that has no programming skills. Linguistic preferences Given the complexity of the topics that will be treated and the need to communicate with the programmer to deal with the specific techniques that have not found space in the document on the functionalities, it would be preferable to communicate in Italian with those who will carry out the project; this preference will affect only the choices of the programmer for the same estimate provided.
