Backend on FastAPI with ~50 endpoints

Hello!
I am interested in your offer to create a backend on FastAPI for the mobile application Coding Train.
I am ready to implement a complete MVP with Supabase, Stripe, OpenAI, clean modular code, and documentation.
Write to me, and we will discuss the details!

Hello.
I am ready to take on the development of the backend on FastAPI according to your technical specifications and Figma mockups. I have looked at the materials; the project is quite extensive, but the structure is clear. This is exactly the type of tasks that I handle professionally.
I have experience building production services on FastAPI using DDD, Clean Architecture, and event-driven approaches. Therefore, the architecture you describe is familiar to me; I will immediately build the right framework so that the code is maintainable and scalable. What I can guarantee is a neat, structured project on FastAPI; the domain logic is separated into services, repositories, and entities without mixing levels; a complete REST API that corresponds to the mockups and business logic; correct implementation of complex scenarios, not temporary workarounds; integration with the database, migrations, validation, modular tests; and proper documentation (Swagger/OpenAPI).

As for the timeline, the estimate is 6–10 weeks.
Regarding the cost, preliminarily: from 1500 to 3000 USD; I will be able to provide a final figure after clarifying the details. If you need a production-level backend that can be easily connected to a mobile application, I am ready to discuss the architecture and propose an initial development plan.

Hello.
I have reviewed your requirements.
Your project requires the creation of a full-fledged FastAPI backend, aligned with the Figma layouts and technical specifications, and I am ready to provide a clean, scalable implementation according to DDD and Clean Architecture. I will properly structure all domains, modules, and entities, implement the necessary CRUD endpoints, and handle more complex logic with a clear separation of tasks and event-driven patterns where necessary. Throughout the development, I will ensure code quality through testing, debugging, and thorough integration with the mobile application logic to match the expected behavior shown in Figma. With my experience working with large backend systems, I can provide a maintainable codebase suitable for a production application on Google Play and iOS.

Hi Alexandr,

I am excited to apply for the freelance backend developer role for Metaokee. With extensive experience in FastAPI, Python, and PostgreSQL, I specialize in building scalable, secure, and maintainable backend systems aligned with Clean Architecture and DDD principles.

I have designed complex CRUD APIs, handled edge cases, and implemented real-time adaptive logic—skills directly relevant to Metaokee’s multi-step registration, quizzes, and progress tracking workflows. I also collaborate closely with frontend developers to ensure smooth integration with React-based interfaces.

I am comfortable refining technical requirements, focusing on critical items (==important==), and delivering high-quality code ready for commercial launch on Google Play and iOS. I would be happy to provide a timeline and pricing after discussing the scope in more detail.

Looking forward to contributing to Metaokee’s mission to transform learning with AI.
…
Best regards,
Jeo Vincent Carretas

Hello, I've checked your google docs and Figma design carefully.

As a full stack developer, I have enough experience in Frontend development and API integration.
Your figma design only has mobile version.
Do you want only mobile app or web app and mobile app?

If you want only mobile app, I can build your project with React Native + Expo.

In your google docs, you already mentioned about Folder structure of Frontend and Backend.
… I can develop frontend from scratch or continue in your previous frontend code(But I need to check carefully before I start my working.)

About payment, i'd like to discuss in more detail

Hello,
I reviewed your technical specification and Figma layouts. I can develop the entire backend in FastAPI using DDD and Clean Architecture, including all CRUD endpoints and complex logic.
My estimated timeline is 8–12 weeks, and my budget for the full backend implementation is $2,500–$4,000.
I’m confident in delivering clean, maintainable, and well-tested code.
Looking forward to cooperating with you.

Thanks.`

Hello.

I am a NodeJS developer. I am ready to take on the task. Write to me, we will discuss.

Hello! I carefully read the document "Educational App – Production (CLEAN)" and I see that it is not about a regular application, but about a full-fledged adaptive learning platform with LLM (OpenAI/Gemini), gamification, complex analytics, and an admin panel. I work with Python / FastAPI / PostgreSQL / SQLAlchemy and frontend (React / Vue / Tailwind), I have created complex CRM/ERP systems, dashboards, integrations with external APIs, payment services, etc. I am accustomed to working with clear architecture, linters, tests, CI/CD, and code style guides.

Hello!

I have a question regarding Event-Driven: are you planning to use an external broker (RabbitMQ/Redis) or an internal implementation?

I have 4 years of experience with Python (FastAPI) and databases. I understand the importance of proper architecture and testing. A volume of 50+ endpoints and working with Figma is a process I am familiar with.

Flexible deadlines are suitable. I am ready to discuss the details.

The task is extensive but interesting. I will handle the layouts and logic, I know FastAPI very well. I can provide a reliable backend for the project. I have an understanding of how Event Driven systems work under the hood. I will also write tests.

Hello!

I can build a FastAPI backend for you in a clear, neat architecture and calmly bring all 50 endpoints to release. The main part is CRUD, and I will cover complex areas with tests to ensure nothing breaks during integrations. For convenience, I will add a ready-made Postman collection and a simple progress screen via the API, where you can see which methods are already ready and tested. This always helps the team to pick up the code faster and ask fewer clarifications in the chat.

The entire volume is estimated to take 6–8 weeks, with a budget of about 5,000 dollars. If you need the most basic MVP first — 3 weeks and 2,500 dollars.

As soon as we clarify everything in private messages — I will start immediately.

Thank you for describing the task so thoroughly!
