Fullstack Developer (Telegram Mini App / AI Integration)

Budget: 25000 UAH Deadline: 21 days

Hello! Your project is a perfect match for my stack. I have experience building complex systems (like integraljobs.cz), so I understand how to work with large data sets and architecture under load.

Briefly about what I offer for your TMA:

Backend: I will use FastAPI for the fastest processing of sports feeds and asynchronous work with LLM.

AI logic: I will set up prompts in JSON mode for stable generation of predictions that do not "break" the frontend.

Data: I will implement proper caching (PostgreSQL/Redis) so that the statistics pipeline works without delays.

TMA & UX: I will create a technological interface in React that works perfectly within Telegram.

Deadline: We will meet in 3-4 weeks. I use AI tools to speed up development without losing quality.

I am ready to discuss the details of integrating sports APIs and the paywall logic in the chat. Stay in touch!

I have indicated the price for developing the basic MVP (the application framework and integration of the main sports feeds). We will discuss the full estimate after a detailed review of the layouts. Expand

Budget: 26000 UAH Deadline: 15 days

Hello.
I have familiarized myself with the project. I see this as an MVP Telegram Mini App for sports analytics with a focus on a stable backend, integration of external sports data APIs, caching, AI-generated predictions, and access logic within the Telegram ecosystem.
On my side, I can cover:
backend in Python / FastAPI
integration of sports data providers
caching and data normalization
integration of LLM API for generating predictions based on structured data
paywall / access levels
trigger messages via Telegram Bot API
database design for further scalability
For such tasks, it is important not just to connect the API, but to build a fast and stable framework: data retrieval, processing, caching, analytics generation, and correct delivery of results to the user in the Telegram Mini App.
Deadline: 15 days
Cost: 26,000 UAH
If you already have ready-made layouts and clear logic for scenarios in TMA, a strong MVP can be assembled quite quickly and then scaled in functionality. Expand

I am developing bots for Telegram using NodeJS. I am ready to take on the project. Write to me, and we will discuss.

Budget: 25000 UAH Deadline: 21 days

Hello!

I have experience in developing Telegram Mini Apps and full-stack solutions (React + Node.js / FastAPI). I have worked on projects with API integration, data caching, and connecting LLM (including generating structured responses).

I am ready to design the architecture, implement analytics, and build a stable TMA by your deadline (2–3 weeks).

We can discuss the details and get started right away.

Budget: 25000 UAH Deadline: 14 days

Good day👋
Roman, I see here not just TMA, but a product with data, paywall, and AI logic - these are exactly the tasks I can handle.
I will create the architecture from scratch: a fast front end for Telegram, a backend with caching of sports feeds, integration of LLM for structured predictions, and triggers through Bot API.
I am also considering the verification of actions and database scaling separately.
I have experience in Telegram bots and Mini Apps, so I can quickly assemble a working MVP in 2-3 weeks and bring it to a quality release.
Shall we discuss the details?

Budget: 24999 UAH Deadline: 3 days

Hello!

Hello!

I looked at the responses — many offer a standard stack, but in your project, the main difficulty is not in the technologies, but in the combination of real-time data + LLM + Telegram UX within tight deadlines.

If we go "head-on," there are risks:
— overload of API providers (limits + delays)
— unstable responses from LLM (break JSON / UI)
— lags in the Telegram Mini App with live data

How I would implement the MVP in 2–3 weeks:

Data and caching
Separate the streams:
— prematch (cache for hours)
— live (update every 10–15 seconds via Redis)
This will significantly reduce the load and speed up TMA.
AI analytics
Do not query LLM "on the fly" for each user.
Generate forecasts in advance (cron/queue) + store as structured JSON.
This will provide stability and instant feedback.
Telegram Mini App
Focus on speed:
— minimal payload
— aggressive caching on the front end
— preloading key data
Paywall
I will immediately incorporate server-side validation + postback logic to prevent access from being bypassed.

Regarding timelines:
👉 It is realistically possible to meet the 3-week deadline if we clearly define the MVP (without overloading with functionality)

A little about me:
— experience with Telegram Mini Apps and bot API
— worked with FastAPI / Node.js + LLM (JSON mode, prompt engineering)
— completed projects with real-time data and caching

I can offer:
— a quick start (breaking it down into phases over 3 weeks)
— a clear architecture without "over-engineering"
— a focus on making it work reliably, rather than just "getting it done"

Let's discuss: I can quickly draft an MVP plan and specify what will definitely fit within the timeline and what is better to postpone. Expand

Budget: 27000 UAH Deadline: 20 days

Hello!

The project is very ambitious, and the 3-week deadline is strict but absolutely realistic if we do not "reinvent the wheel" and use the right microservice architecture and ready-made patterns for Telegram Mini Apps.

I have relevant experience: I have developed TMA applications using React + FastAPI and am deeply involved in working with LLM (OpenAI/Gemini) for generating analytics based on structured "raw" data.

How I will solve your tasks (Technical vision):

1. Integration of Sports API & Caching: Sports providers (e.g., API-Football or Sportmonks) have strict limits. I will build a pipeline: FastAPI fetches data (fixtures, lineups, H2H) and stores it in Redis. Pre-match data will be cached for hours, Live statistics for 10-15 seconds. This will save the budget on the API and ensure instant loading of TMA.
2. AI Analytics and LLM (No hallucinations): I will not just send text to the neural network. We will collect the match context in a strict format (xG, injuries, head-to-head history) and request a response from LLM exclusively through JSON Mode (Structured Outputs). The backend will parse JSON and send ready-made blocks to the frontend: "Probability of victory," "Key factor," "Risks."
3. Frontend (TMA): I will use React.js + TailwindCSS. The interface will work at the speed of a native application. We will definitely implement support for dynamic Telegram themes (light/dark) and haptic feedback through TWA SDK.
4. Paywall & S2S Postbacks: I will implement a system of access levels (Free / Pro). We will set up endpoints to receive webhooks from payment systems (Telegram Stars / Crypto Pay) or CPA networks (registration by ID).
5. Retention (Triggers): We will raise asynchronous workers (Celery + Redis). The bot will push users: "The Real-Barca match will start in 30 minutes, AI has already prepared a forecast [Watch in App]."
Timeline (Sprints of 3 weeks):

- Week 1: Database setup (PostgreSQL), integration of Sports API, caching layer, basic user logic, and Paywall.
- Week 2: Prompt engineering, connecting LLM, parsing AI responses, developing API for the frontend.
- Week 3: TMA layout (React), linking with the backend, setting up Retention pushes, debugging, and release.
Budget: Since the deadline is tight and requires full focus, the estimated range for the MVP will be $2500 (negotiable, depending on the number of screens in the design). Expand

Hello! I am interested in the task of creating a platform for sports analytics with predictive AI in the format of a Telegram Mini App. My experience includes developing complex backend systems with ML/AI integrations and creating interactive web applications, perfectly suited for TMA. I am ready to offer architectural solutions that will ensure the quality and scalability of the project. Could you clarify the key metrics for predictive analysis that are planned to be implemented in the first phase? Let's discuss your budget and realistic deadlines for completion.

Budget: 27000 UAH Deadline: 21 days

Hello, Roman!

We consider your project PiarHunt a priority. We work in tandem: I (Nina) am responsible for management, technical specifications, and meeting deadlines, while the technical part "turnkey" (Frontend + Backend + AI) is handled by a Fullstack developer.

We have real experience in developing Telegram Mini Apps and a deep understanding of how to integrate external data with language models.

Here’s how we will implement your TMA in 3 weeks:

Architecture and Speed: We use the combination of FastAPI + React. This will ensure an instant response from the interface, which is critical for live sports events.

AI Analytics (Gemini/GPT): We do not just send requests. We use JSON mode to obtain structured forecasts and advanced Prompt Engineering so that the AI provides analytics based on real H2H and lineups, rather than "hallucinating."

Data Pipeline: We will set up aggregation of sports feeds with aggressive caching in Redis/PostgreSQL. The user will see statistics instantly, without waiting for a response from the data provider.

Paywall and Logic: We will implement a system of access levels and verification through postbacks. We will integrate trigger notifications about the start of matches or score changes.

UI/UX: We will design a responsive "technological" interface that will feel like a native app within Telegram.

We understand that a 3-week deadline is a challenge. Therefore, we use internal AI pipelines to speed up coding and testing, allowing us to deliver results twice as fast as traditional teams.

We are ready to discuss the layouts and start working.

The cost (70,000 UAH) is an estimate for the full implementation of the MVP in 3 weeks: from architecture and layout of the TMA to setting up AI prompts and caching feeds. We understand that your budget may be flexible, so we are ready to discuss the final amount after reviewing the layouts and specifications of the sports APIs. Expand

Budget: 25000 UAH Deadline: 20 days

Hello! I am a Fullstack developer, stack: React + Python (FastAPI), PostgreSQL, integrations with Telegram Bot API, LLM (OpenAI/Claude — JSON mode, prompt engineering), REST API of sports providers. I have experience building AI agents with real-time data processing, caching, and notification systems. What I can cover from your tasks: Client-server architecture TMA from scratch, integration of sports feeds (fixtures, H2H, live stats), AI analytics through LLM with prompt optimization, paywall logic with postbacks, trigger notifications through Bot API, adaptive mobile layout. I am ready to discuss the details, show examples of work, and agree on payment. When is it convenient to call?

Budget: 25000 UAH Deadline: 20 days

Hello.

I have reviewed the description — the project is clear, the tasks are essentially classic, but with normal complexity due to real-time data and LLM.

I have experience in developing web applications and integrations with APIs, including with Telegram (bots/mini apps). I have worked with Node.js and Python (FastAPI), and on the front end — React. I understand how to build architecture for such tasks: collecting and caching sports data, processing, generating analytics through LLM, and presenting it to the user in a convenient format.

Based on what is described:
— I can build TMA from scratch (frontend + backend)
— set up integration with sports API + a proper caching layer
— implement prediction generation through GPT/Gemini (with an adequate response structure)
— create an access system (paywall, levels, user binding)
— set up notifications through Telegram
— build a fast and adaptive interface for mobile devices

Regarding timelines: 2–3 weeks in total is realistic, but it depends on the volume of the MVP and the readiness of the layouts/technical specifications. It’s better to have a quick call or discuss the details to avoid discrepancies in expectations.

We can discuss:
— what specific functionality should be in the first version
— what data sources you plan to use
— how the prediction logic should look
— and after that, I will be able to provide exact timelines and costs

If convenient — let’s move on to the details. Expand

Hello!

We have experience in developing Telegram Mini Apps + AI integrations — we work with the stack React + FastAPI + PostgreSQL + LLM API. We have developed TMA with paywall logic and trigger notifications.

For your project, we envision the following architecture:
- TMA frontend on React + Telegram WebApp SDK
- FastAPI backend with caching of sports feeds (Redis) — to avoid hitting the provider on every request
- LLM predictions: structured JSON mode (Gemini/GPT) with optimized prompts for fixtures + H2H + lineups
- Paywall: access levels through Telegram Bot API + postback verification
- Retention: event-driven notifications through the bot (live events, deadlines)

We will create an MVP in 14 days, including a responsive UI based on the designs.

Clarification: which sports data provider do you plan to use (API-Football, SportRadar, other)? This affects the caching structure.
