Hello! Your bot is a full-fledged EdTech platform with secure video, Stripe subscriptions, a role model, and billing for tax advisors, and I see all the technical nuances: presigned URLs via DigitalOcean Spaces, a Stripe webhook chain for three plans, a 5-minute editing window via Celery beat, and bilingual content with language fixation at the challenge level. Stage 1 + Stage 2 turnkey on the stack aiogram 3 + FastAPI + PostgreSQL + Docker — 20 working days, 40,000 UAH. Where do we start, with setting up Stripe Checkout and webhook logic or directly with the database architecture and admin panel? I look forward to collaborating!

Hello!

The task is clear: we need to build a paid Telegram bot with challenges, Stripe payment, 24-hour lesson availability, an admin panel, and secure access to content without "raw" solutions at the start.

What I can deliver:
— implementation of Stage 1 as a stable MVP: payment, access activation, lessons, practical tasks, basic admin panel, VPS;
— proper architecture for Stage 2, so that affiliate programs, promo codes, statistics, and roles won't need to be redone from scratch later;
— smart content protection: Telegram Protected Content where appropriate, and temporary access to videos without open links.

… I work with Python, aiogram, FastAPI, PostgreSQL, Stripe, Docker/VPS, so I can build not just a bot, but a well-thought-out system for selling and completing challenges.

Hello
I have extensive experience (over 7 years) in creating complex solutions - from bots with web interfaces to executed systems, with integrations and payments. (from no-code platforms to n8n and pure code)
Your project is very interesting in terms of functionality - it is a whole system, not just a bot. Some projects are in my portfolio, and I can also demonstrate the work of some projects on a call.
I would be happy to collaborate.

Hello! I carefully read the entire technical specification, not just the project description.

I see the essence: an educational bot with challenges, payment through Stripe Checkout + webhooks (checkout.session.completed, invoice.paid, customer.subscription.*), automatic access activation, lesson issuance strictly once every 24 hours from the first lesson, practical tasks in the form of a 3-field format (1000 characters each, with a 5-minute editing window and fixation afterwards), roles of admin / supervisor-psychologist with privacy (the supervisor does not see user contacts), generation of invoices with export for tax advisors, and protected video through presigned links in DigitalOcean Spaces (without permanent direct links). Stage 1 — working MVP for payment→access→lessons→verification, Stage 2 — affiliate program, promo codes, advanced analytics, 2FA, exports.

The stack completely matches how I would implement this: Python + aiogram 3 + FastAPI, PostgreSQL + SQLAlchemy/Alembic, Stripe SDK + Webhooks, Docker + Nginx on VPS, GitHub.

Why me: I write exactly such things. Recently, I built a trading bot for Bybit from scratch — WebSocket connection, order management, real-time event processing, Telegram notifications, and a web dashboard. So, integrating payment/event APIs through webhooks, background tasks, and admin panels is my daily work. Examples are in my profile.

Two clarifications to provide an accurate fixed estimate:
… 1. Do we generate the invoice as a PDF on our side using your template (better control over appearance and export for tax advisors), or through Stripe Invoices?
2. Is the content for the first challenge (video/PDF/tasks) already ready for upload through the admin panel, or does the bot start with 1 demo challenge, and you fill in the remaining 20 yourself?

I suggest breaking it into 2 phases: first Stage 1 (MVP), after acceptance — Stage 2. This way, you have less risk and clearer acceptance. I support a 14-day guarantee based on your technical specification.

I am ready to send a step-by-step work plan today.

Good day!

I have significant experience in developing Telegram bots using Python (Aiogram), CRM systems, educational platforms, payment integrations, and administrative panels. I have reviewed the specifications and can say that the project is well thought out and essentially represents a full-fledged LMS platform within Telegram with payments, roles, content management, and a user support system.

For implementation, I would use the stack proposed in the specifications:

• Python + FastAPI
• Aiogram 3
• PostgreSQL
… • SQLAlchemy + Alembic
• Stripe Checkout + Webhooks
• Docker
• Nginx
• GitHub
• DigitalOcean Spaces (S3) for secure content storage

It is particularly important that the project already includes the correct architecture for further scaling: separate user roles, multilingual support, Stripe subscriptions, a partner system, promo codes, analytics, and handling large volumes of content.

From a technical standpoint, I am ready to implement:

• A Telegram bot with multilingual support;
• Stripe integration with automatic access activation via Webhook;
• A system of challenges and lesson openings according to schedule;
• Support for video, PDF, audio, and practical tasks;
• User personal accounts;
• Administrator and supervisor roles;
• A system for checking homework and comments;
• Generation and sending of invoices;
• Integration of DigitalOcean Spaces with temporary presigned URLs;
• An administrative panel for complete content management without developer involvement;
• Export of payments and reports for accounting.

I also have experience in building systems with access roles, time restrictions, task planners, automatic notifications, and secure handling of payment systems.

I am ready to discuss the current version of the specifications in detail, propose an optimal project structure, and take on the implementation turnkey. We can discuss the details of cooperation in private messages.

Hello! I am Volodymyr, the founder of the engineering agency Vaysed. Your technical task is composed at the highest level, with the details of business logic and architectural requirements clearly outlined, which significantly facilitates the project assessment.

We have deep expertise in the proposed technology stack, including Python, FastAPI, Aiogram 3, PostgreSQL, and Docker, and we specialize in developing similar high-load ecosystems. The architecture of your project is a full-fledged LMS within Telegram. We have already solved similar engineering tasks during the development of our platform RESTART 2026, where we implemented automated distribution of educational materials with strict timing control, reliable processing of financial transactions and subscriptions through Stripe webhooks, as well as role distribution between administrators and curators.

We are well acquainted with the mechanics of content protection: generating temporary links through S3-compatible storage ensures that your paid videos will not be leaked into the public domain. You can find more details about our technical approach on the official agency website https://vaysed.me/. Or in the freelance profile.

Considering the scope of work for both stages, which includes the development of the bot, web admin panel with 2FA, Stripe integration, PDF invoice generation, and affiliate program, the estimated implementation time will be from 30 to 40 working days. The project requires writing a reliable backend and thorough testing of financial logic.

I suggest initially implementing only the first stage with basic functionality, Stripe integration, and lesson distribution, and launching the MVP, while deferring the affiliate program and analytics to the next sprint. Please message me privately to agree on this approach and start working.

Hello!
I have reviewed your specifications. The document is very well written, the architecture is clear, so I am ready to start working as early as today.
On my part, I would like to suggest a small improvement to speed up development: instead of writing a simple admin panel from scratch, I propose to integrate Django Admin. This is a reliable "out of the box" solution that will save a lot of time on interface development while giving you complete and convenient control over lessons, rates, content, and specialists. We will implement the bot's backend using FastAPI + aiogram 3, as you planned.
Regarding the timelines (we will speed up due to the ready admin panel):
Stage 1 (Bot, Stripe, 24-hour logic + Django Admin): 10–12 working days.
Stage 2 (Affiliate program, promo codes, analytics): 5 working days.
In total: we plan to complete within 14–17 working days from the start.
Of course, I guarantee the security of content through temporary links (presigned URLs) for DigitalOcean Spaces and work through Freelancehunt Safe — everything here is strictly according to the specifications.
If the timelines and stack are acceptable — let's have a call or chat to discuss the details and we can start Safe.

Hello!

I have reviewed your technical assignment. The description is very clear and structured, which greatly simplifies understanding the final result. I specialize in developing comprehensive solutions for businesses and automating processes (working both through n8n and with pure code using modern AI tools).

The task is completely clear to me. Implementing the logic with a strict 24-hour step, separating roles for psychologists (with the concealment of users' personal data), connecting Stripe Checkout (including handling complex webhook events for subscriptions) and protecting content through temporary presigned links in DigitalOcean Spaces — all of this can be implemented without any issues. I have also studied the context and structure of the database (PostgreSQL), and the architecture is absolutely functional.

You can view some of my similar systems and custom calculators/assistants in my portfolio. There are examples of subscription implementations, control systems, and application distribution logic.

To finalize the timelines and start working through Safe, I have a couple of clarifying questions regarding the technical assignment:
…
Regarding the generation of PDF invoices (Rechnung): are we doing a full custom PDF file generation on the backend based on your template, or is there a plan to use built-in invoices from Stripe itself (Stripe Invoicing)?

In point 13.1, it is stated that there will be 20 challenges at the start. Does this mean that the architecture of the admin panel should support the creation of this number, and you will upload the content (videos, tasks) yourself through the admin panel, or do I need to populate the database with these 20 ready-made programs at the start?

I look forward to collaborating! Best regards, Tetiana.
