Description: It is necessary to create a JavaScript script for the Tampermonkey extension. The script will work in an internal CRM system.Logic of operation: The script must read the unique text ID of the current active dialogue on the page (there are a total of 5–10 different IDs). Depending on the ID, the script takes the corresponding text instruction (System Prompt) from the settings. The mapping of parameters by ID should be moved to a separate convenient settings window for the script. When a new message appears in the chat window, the script sends this text along with the prompt via the OpenAI API (model gpt-4o-mini). The received response is inserted into the text input field and initiates sending with a random delay of 20–45 seconds to simulate the natural operation of the operator.Work is purely with text. Budget — 6000 UAH. I am waiting for proposals from developers with experience in working with the OpenAI API and writing browser automation scripts.

A web service needs to be developed for automating the operations of coffee shops and small food service establishments. The product should have functionality similar to Poster POS, but with its own design, architecture, and source code. Copying the code or interface of Poster is not anticipated. The plan is to create a full-fledged commercial SaaS product that various coffee shops can use in the future on a subscription basis.In the first stage, an MVP needs to be developed Main functionality: registration and authorization of the establishment owner; creation of one or several establishments; management of employees and roles; catalog of products, categories, and modifiers; adding sizes, flavors, and additional options; cash interface for processing sales; opening and closing cash shifts; various payment methods; returns and order cancellations; inventory accounting and write-offs; basic stock accounting; sales history; reports on revenue, products, shifts, and employees; loyalty program for customers; adaptive operation on tablets, laptops, and smartphones; administrative panel for the service owner; tariff plans and restrictions according to the tariff.Future plans include mobile application; integration with payment terminals; receipt printing; integration with fiscal services; delivery and online ordering; table reservations; advanced analytics; API for third-party integrations; integration with accounting and CRM systems.Important requirements the system must be designed to operate multiple independent establishments; data of each client must be isolated; scalability of the product must be anticipated; secure handling of financial and personal data is required; the code must be structured and suitable for further development; technical documentation is needed; rights to the source code are transferred to the client after payment. At this moment, the design is absent, so a separate assessment of UI/UX design is needed or a ready-made solution for the MVP should be proposed.Please include in your proposal experience in creating SaaS, POS, CRM, ERP, or accounting systems; examples of similar work; proposed technology stack; team composition; estimated cost of the MVP; development timeline; what exactly is included in the proposed cost; cost of further support; whether you are ready to work in stages with payment for each completed stage. Preference will be given to performers or teams that have already developed cash, inventory, restaurant, or multi-user SaaS systems.
