Hello, I worked on the Telegram Mini App "Bulletin Board" with tag:7748 - a local trading platform with chat, moderation, and payment system, processing 500+ ads daily. The project is similar to your needs with a comparable scaling architecture!
I’m curious if you plan to integrate with other payment systems besides LiqPay to expand your user audience?
I suggest we get in touch; I will provide you with free technical consultation and we can create a development plan + I will tell you about my team! ✨

8589 26 0 1 Hello! I can develop a Telegram Mini App with an architecture for further scaling into a mobile application and a full-fledged web platform, with backend API, PostgreSQL, and a modern project structure. I will implement all MVP functionality: posting ads, internal chat, Telegram notifications, LiqPay, moderation, subscriptions, cloud storage for photos, and an admin panel with flexible monetization settings. The project will be fully custom, with the transfer of all source codes, GitHub repository, and access, so you can comfortably continue to develop the platform.

3459 48 2 Hello! I have experience working with all the necessary technologies, namely: developing Telegram bots with mini apps, writing live chats via webhooks, working with S3 for photo storage, PostgreSQL, and integrating payment systems (including LiqPay). On my part, I guarantee a scalable backend for further mobile development, documentation, and I will also assist with deployment on the server for 24/7 operation. You can see many projects with relevant experience in my profile.
Feel free to reach out - I would be happy to help!

1385 6 1 Hello, Serzhyo!
To gain a better understanding of the project, please clarify:
1. What infrastructure do you plan to use for deployment (cloud services or your own servers)?
2. Do you have any preferences for cloud storage for photos?
3. Are you planning to integrate with other messengers in the future?
4. What are the requirements for user data security?
My approach to implementation:
… 1. I create an architecture considering scalability, so that it will be easy to add a mobile application and web version in the future.
2. I implement an authorization system through Telegram WebApp with the ability to change the profile.
3. I set up functionality for posting ads with validation of required fields and highlighting errors.
4. I deploy an internal chat with notifications via a Telegram bot and message storage in the database.
5. I provide paid functionality through LiqPay integration with settings in the admin panel.
6. I optimize photo storage and compression for quick access and minimal storage costs.
As a result, you will receive a ready MVP project, fully prepared for further scaling. Please send your answers to the questions in private messages so that I can offer specific solutions and deadlines.

284 Ready to develop an architecturally correct Telegram Mini App that will initially address the MVP tasks and can easily scale to iOS/Android and Web in the future by offloading all business logic to a separate REST API. All development will be conducted in your GitHub repository, and the infrastructure (server, database, cloud) will be deployed strictly on your accounts. I suggest discussing the technology stack and interface details in the chat.

280 1 0 Hello. I am ready to take on the development of the MVP for your Mini App. I will lay the architecture for scalability right away (FastAPI on the backend + PostgreSQL), so that in the future it will be easy to connect a mobile application and a web version.
What I will do on the technical side:
Backend: REST API with a clear structure, using Cloud Storage for photos (with automatic compression to WebP up to 600px).
Chat and notifications: I will implement an internal chat using sockets or long polling with storage in the database and duplication of notifications through a bot.
Payment: Integration of LiqPay via webhook for paid ads and promotion services.
…
Admin panel: A convenient panel for moderation, managing banners, and pricing plans.
The code will be commented, and the entire development process will be through GitHub on your accounts. I am ready to discuss the stages of implementation and timelines.
