A Telegram bot is required to serve as a client interface for our system. The bot should be as lightweight as possible. All main business logic and database interactions are handled on the backend side. The bot's task is to interact with the user, collect data from them, and exchange it with the backend using the gRPC protocol. The project should be implemented on the .NET 8 / .NET 9 platform using the Telegram.Bot library (or an actively supported alternative framework in C#).Functional Requirements1. User Interface (User Flow) Authorization / Registration: Upon first launch (/start), the bot requests the user's phone number via the standard Telegram contact sending button. This data is sent to the backend for verification or registration. Main Menu: A persistent Inline or Reply menu with the following sections: My Profile: Display the current user status, balance, and active subscriptions (data is requested from the backend). Create Application: A step-by-step scenario for filling out a text application. The bot sequentially collects: title, description, and attached file (if any), after which it sends the data package to the backend. Application History: A list of the last 5 user applications with their current statuses. Notifications (Push): The bot must be able to receive asynchronous messages from the backend and instantly forward them to specific users (e.g., about changes in application status).2. Technical Architecture and Integration gRPC Client: A gRPC client must be implemented within the bot. We will provide ready .proto files describing contracts for: User authentication (AuthenticateUser) Getting profile (GetUserProfile) Submitting an application (CreateApplication) Getting the list of applications (GetApplicationList) Message Streaming: To send notifications from the backend to the bot, it is necessary to implement gRPC Server Streaming or support duplex streaming (to be discussed at the start stage). Local Storage: The bot should not have its own heavy database. To store temporary user states (FSM / Finite State Machine) while filling out forms, a distributed cache (e.g., Redis) or built-in RAM with the ability to quickly switch to external storage should be used.

A Telegram bot needs to be created with a program that will monitor listings on three apartment rental websites (olx, lun, rieltor.ua) and send them structured in Telegram.

it is necessary to organize a way to collect newly created individual entrepreneurs and, if possible, limited liability companies. whether it's parsing or something else - you tell me what this method should be

Good morning,I will commission the creation of a stable and reliable solution for automatically monitoring prices and availability of products from a specific large Polish online store in the RTV/AGD sector.Project goal: The system must regularly check selected product links and, in case of a price change or availability status, send a notification (preferably via Telegram, Discord, or email – to be determined).Challenge: The store's website has very aggressive anti-bot systems (Akamai/Cloudflare). Ordinary scripts that fetch the page code are immediately detected and blocked. The solution must effectively bypass these protections, mask bot traffic, and operate stably over the long term, without constantly throwing "Access Denied" errors.What I expect from the contractor: Proposing a complete architecture and technology (I do not impose a programming language or specific tools). Delivering a ready-made solution that I can easily launch and manage. Suggestions regarding infrastructure (e.g., what proxies will be necessary for the system to operate smoothly).In response to the announcement, please briefly describe: What approach/technology do you propose to effectively and sustainably bypass the store's protections? How do you see the issue of sending notifications? What is the estimated cost of execution and time of completion?I invite you to submit your offers.

About the Company Trading company. We work with a product group of more than 2000 items across different categories.Current Situation Currently, the nomenclature is maintained in Google Sheets — data is consolidated by tabs (categories). Tab Structure: Product name Price groups: cost price, wholesale, retail Characteristics: weight, quantity per package, etc. Important: the number of columns varies for different product categories, as they have different characteristics.Why the Current Solution is Inadequate Google Sheets does not allow setting access rights at the level of individual columns. We need to: Grant users rights to view certain columns (for example, only cost prices) Grant rights to edit certain columns (for example, retail prices) While restricting access to other columns in the same tabWhat Needs to Be DoneMain Requirements Flexible Rights Management System Access at the level of individual columns (read/write) Assignment of rights by roles or users Management of rights without the involvement of programmers Support for Different Data Structures Different product categories have different sets of characteristics Adding new columns/characteristics without programming Independence from Developers Administration by internal staff Adding categories, columns, users — through the interface Integration with ERP Exporting current prices to our ERP system Export or automatic integration via API Data Analysis Using AI (preferably) Ability to analyze the entire nomenclature list Enrichment, verification, recommendations — if you have ideas, please describeExpected Result A working solution in which: The nomenclature is structured by categories with different sets of characteristics Column rights are flexibly configured (view/edit) Data is exported to ERP The team can manage the system independentlyWhat We Need from You When Responding Describe in general terms how you envision the solution: What tool/platform do you propose
