Fullstack Developer (Telegram Mini App / AI Integration)

Budget: 20000 UAH Deadline: 30 days

Hello! Your project for developing a sports TMA service is exactly the stack and level of tasks I specialize in. I have experience building complex systems with external API integration and neural networks.

How I will implement your project:

Architecture & Performance: I will use FastAPI (Python) for the backend. This will ensure maximum processing speed for sports feeds and asynchronous work with LLM without delays for the user.

AI-Analytics (Gemini/GPT): I have a deep understanding of Prompt Engineering. I will configure the generation of predictions in JSON mode so that the data from the neural network is correctly structured in the interface (statistics, probabilities, text).

Data Pipeline: I will implement a caching system (Redis/PostgreSQL) for sports data (fixtures, H2H) to minimize requests to providers and speed up the application's response.

TMA & UX: I will develop a lightweight and "technological" frontend on React, fully adapted for Telegram mobile clients. I will integrate a notification system and user retention mechanics.

Monetization: I will implement a reliable paywall logic and action verification through postbacks for stable business model operation.

My experience:
I have developed complex platforms with large data sets, where speed of filtering and database stability were critically important. I actively use AI tools to accelerate development, which will allow me to meet your deadline (3-4 weeks).

I am ready to discuss the architecture and sign an NDA to review the mockups. I'm in touch! Expand

Hello. I have extensive experience in developing TMA on Next.js/Nest.js. I am ready for collaboration.

Budget: 25000 UAH Deadline: 24 days

Hello.

The task is clear: I need not just a bot, but a full-fledged **Telegram Mini App** with a proper client-server architecture, integration of sports data providers, an AI layer for analytics and predictions, roles, real-time notifications, and a fast mobile UI within Telegram.

I have over 3 years of experience in fullstack/backend development. I work with **Node.js, React, API integrations, backend architecture, and AI services**, so this stack is familiar to me: **React / TMA, Node.js or FastAPI, PostgreSQL/MongoDB, Telegram Bot API, external sports APIs, GPT/Gemini**.

What I can cover for the project:
— design the architecture of TMA and backend;
— connect and normalize data from sports data providers;
— implement AI logic for generating structured forecasts and analytics;
— create roles, authorization, and user scenarios;
— set up real-time notifications via Telegram Bot API;
— build a fast and neat interface based on ready-made layouts.

I approach such tasks not as a “quick MVP on the fly,” but as a product that can be properly developed later without constant refactoring. For me, the key here is clean architecture, predictable backend, careful work with API/AI layer, and stable logic within Telegram.

I am ready to quickly get to work, go through the scope, break the project into stages, and immediately start development.

If it is important for you to receive not just code, but a working and maintainable TMA product — this is exactly my format. Expand

Hello.

The project is clear — it is a full-fledged product, not just a Telegram Mini App with an interface. I have experience in developing TMA and working with APIs, real-time data, and logic within Telegram, so I can handle the task from start to finish.

I have worked with:
- Telegram Mini Apps (WebApp inside Telegram)
- React + API integrations
- systems with dynamic data and high update frequency
- integration of external APIs (including caching and optimizing requests)
- LLM (GPT/Gemini) — text generation and working with structured responses

I understand the specifics of your project:
- working with streaming sports data (fixtures, live, statistics)
- the need for caching and normalizing data
- generating forecasts through LLM with structure control
- access separation (paywall)
- retention through Telegram notifications

What I can implement:
- TMA architecture (frontend + backend)
- integration of sports APIs with caching
- generating forecasts through LLM (with prompt optimization)
- a system of roles and access levels
- integration with Telegram Bot API (notifications, events)
- a fast and adaptive interface for mobile Telegram

How I approach such projects:
- first, I think through the architecture to withstand load growth
- I minimize unnecessary requests through caching and aggregation
- I lay the groundwork for scalability (new leagues, metrics, scenarios)
- I control the cost of LLM (important when scaling)

I am ready to get involved and discuss the details, including data structure, provider selection, and architecture according to your deadline. Expand
