Hello!
I am interested in the Telegram Mini App project — the task looks structured, clear, and has potential for development. I work with Node.js + MongoDB, have a good understanding of microservices architecture, Telegram Bot API, referral systems, accumulations, and event-driven mechanics.
Tech stack:
Node.js, MongoDB, Telegraf / node-telegram-bot-api, Axios, Redis (if there will be a queue), Docker (if needed)

Ready for a call or a test.
I can quickly get into the project and start development. Thank you for the opportunity!

Good day!

I am interested in your vacancy regarding the development of a backend service for Telegram Mini App. I have over 7 years of commercial experience in developing backend solutions, including using PHP (NodeJS, Express, Laravel, Yii2), and have also worked with integrating Telegram bots and mini-apps. I have a good understanding of the architecture of such systems, and I can implement flexible interaction logic with users, resource accounting, events, and actions.

I am ready to develop the backend part with all necessary business logic, API, and integration with Telegram Mini App, ensuring scalability.

Hello, I have carefully read the technical assignment. This is the project I enjoy working on. It has a structure, logic, and clear goals. I understand how to design internal services that are both flexible and reliable, especially when involving user actions, digital rewards, and real-time updates.

I would create a service in Node.js using Express or Fastify, depending on what best suits your deployment process. For data storage, both MySQL and MongoDB can work here. If the data needs to be structured and relational, I would lean towards MySQL. If it is more flexible and nested, MongoDB might be a better fit.

For each user, I will ensure that their Telegram ID, language, and login date are securely tracked. The system will handle accumulations, actions, events, and exchanges, with all rules being strictly followed. I will also include manual triggers for administrator actions so you can run checks or corrections without needing a separate panel.

I have already worked on similar systems where real-time behavior, token logic, and action verification were key. For example, at https://elysianai.com I developed user interactions supported by OpenAI. At https://thedesignersclass.cm I managed internal flows with user states, API-based updates, and structured access control.

If you want, I can guide you through how I will structure the database, routes, and logic for optimal performance and easy future expansion. Let me know how you want to start or if you'd like me to review a sample flow.

Hi!
I am MERN expert and have rich experience in developing of telegram BOT .
Let's discuss more about your app.
Thanks.

Привет,

Это звучит как забавная система для создания. Я уже разрабатывал бэкэнды, где пользователи взаимодействуют с объектами, зарабатывают и обменивают баллы и видят персонализированные результаты. Вот несколько примеров:

https://bedtimestory.ai
https://midjourney.com

Для этого приложения Telegram Mini я бы сосредоточился на том, чтобы все основные механики, такие как ежедневные серии, обмены и логика событий, работали чисто в фоновом режиме, не нарушая поток пользователей. Я также настроил логику вознаграждений, отслеживание рефералов и гибкие таймеры событий в прошлых проектах, поэтому эта структура кажется знакомой.

… Я могу сделать сервис легким, модульным и простым для подключения к макету ReactJS и интеграции платежей на основе обратного вызова.

Дайте мне знать, если вы хотите более подробно рассмотреть потоки объектов или логику ежедневных единиц.
