Development of a custom Telegram web client

Budget: 12345 UAH Deadline: 1 day

Hello, I worked on a custom Telegram web client for a company with 150+ users. I created hidden data and integrated the API as you need.

How do you plan to manage access to contacts in the support team for maximum privacy protection?

I suggest we get in touch, I will consult you for free on the technical side and we will create a development plan + I will tell you about my team!

Good evening, Ruslan
I am interested in your project, ready to take it on and have the necessary experience
I have worked quite a lot with the Telegram API, specifically with MTProto both using libraries and directly, so I understand the technical side of implementation well. However, I developed not clients, but rather automated systems, but I have experience in full-stack development with React.js + TypeScript with a backend in Go or Next.js
I looked at the code base for the client that you mentioned. Good choice, it could be forked and slightly modified to suit your needs, but there is a small catch that could be crucial in your situation. This client works directly with the Telegram API from the browser, and hiding some data in it can only be done formally by removing it from the interface. But the session allows obtaining this data with some effort; it cannot be reliably hidden without almost completely reworking the main logic of this client. You need all API interactions to be done on the server, and the client should only receive data from it. Or at least in WASM in a compiled language, but it's better to move everything to the server. I just want to draw attention to this important point
It would be better to find or write only the chat UI, rather than a full implementation of Telegram with calls to their API
I can take care of this and implement it in a way that would reliably protect client data; please write to me, and after discussing all the details, I will be able to assess the scope of work. I would be happy to collaborate

Hello.
I am an experienced Full Stack developer (React, Node.js, TypeScript, JavaScript) with a proven track record of setting up and extending Telegram web clients for commercial use. Your project focuses on privacy constraints, session management, and controlled functionality, which aligns well with my experience in developing secure communication tools where confidential data must be hidden or access to it restricted. I have worked on projects requiring custom modifications of the Telegram client, API integration, and advanced permission systems that ensure user interactions are only within clearly defined business rules. For your needs, I can implement contact data masking, whitelisted link processing, limited group/channel actions, and support for multiple accounts based on sessions, while maintaining a stable and user-friendly interface. My backend skills in Node.js and REST/GraphQL API will ensure seamless integration for extracting client data into the main window and handling authentication via login and password in API-based sessions. With my experience in both frontend (React/TypeScript) and backend (Node.js) development, I can provide a secure, efficient, and fully customizable Telegram client that meets your commercial requirements.
