Good day!
I am interested in your project AI Fitness Coach and the task of refining the backend on FastAPI. My 5 years of experience in Python development includes deep expertise with FastAPI and building microservice architectures, which perfectly matches your stack and the current state of the project. I also have experience in integrating AI services and developing WebSocket chats, which will be very useful for your AI Coach and WebSocket Chat modules. I am ready to provide consulting support and help finalize the remaining 15-20% of the backend to readiness.

Hello, you chose a good stack.
- I would start with tests to ensure that further changes won't break anything.
- I can conduct a code review, starting with things that might be slow right now, or there might be payment methods.
- Also, a review of the architecture if needed, but that will definitely be after the tests.
- I can also help with deployment, setting up CI/CD.
I can just do reviews/consulting (text, meetings), or dive deeper into the code.
My rate is 20 USD/hour.
Write to me, and we will discuss the details.

Hello. I have been developing Backend solutions in Python for 4 years. During this time, I have worked on projects of varying complexity - from the simplest to full-fledged platforms (an AI platform consisting of several microservices that work together) for automating business processes. I would be happy to help you with your task. I have repeatedly had experience working with someone else's code, and I will gladly consult and identify the strengths and weaknesses of your software. I have a confident understanding of all the listed technologies. I would like to discuss the details of our collaboration in private messages.

Hello!
I have over 3 years of commercial experience with Python/FastAPI and have worked many times with similar microservice architecture: separate services (Auth, Core, AI, Realtime), Redis as a cache and broker, Celery for background tasks, Docker Compose for local orchestration. I have a good understanding of service-to-service communication, isolation of domain logic, and scaling under load.
What I can bring to your project:
* In-depth code review focusing on clean architecture, dependency injection, correct operation of the async event loop, avoiding blocking operations, transactionality, and consistency.
* Security checks: JWT flow (access/refresh), rate limiting, protection of WebSocket connections, validation of incoming data, handling of secrets.
* Refinement of the AI Coach Service: building a stable HTTP wrapper over LangChain/LangGraph, managing state control, handling retries and fallbacks, optimizing latency, preparing for horizontal scaling.
* Performance analysis (N+1 queries, indexes, connection pooling, caching in Redis).
* Recommendations on CI/CD, logging, observability (structured logs, basic tracing), correct migration strategy through Alembic.
I usually work like this: technical audit → structured list of risks and technical debt → improvement plan → implementation.
I am ready to engage in a part-time/consultation format and help bring the backend to a stable production-ready state.
I look forward to collaborating!

Hello! 🤖💪
I have experience working with FastAPI, microservices architecture, and AI modules (LangChain/LangGraph). I am ready to conduct a thorough code review (architecture, dependencies, service boundaries), refine the AI Coach Service (a clear HTTP wrapper over LangChain, state/context management), assist with migrations (Alembic), email notifications, tests, and stabilization of the WebSocket part.
Proposed stack: Python 3.13, FastAPI, SQLModel (Pydantic+SQLAlchemy), PostgreSQL 15, Redis 7, Celery, Docker, Alembic, WebSocket, LangChain/LangGraph.
I am ready to discuss project details in private, with the possibility of long-term collaboration.
Best regards, Andriy!
