My FastAPI-based course platform is almost production-ready, but persistent connection errors with the SQL back-end are blocking launch. The project already contains the full user/course logic; models are defined with SQLAlchemy and the environment variables for either PostgreSQL or MySQL are in place, yet the app still drops or refuses connections under load. I need a Python/FastAPI specialist to review the existing repository, trace the connection failures, and implement a solid remedy. That likely means inspecting the engine configuration, connection pooling, transaction handling, and any Alembic migration issues, then adjusting code or server settings so every endpoint responds reliably. Deliverables • Clean, commit-ready fixes that eliminate the current connection errors • A short report outlining what was wrong, what you changed, and how to replicate the working setup locally and in production • Optional but appreciated: pointers on query optimisation or indexing if you spot easy wins I will provide repo access and database credentials as soon as we start. Once the patched branch runs without errors through my test suite and manual checks, the job is done.

Hi there, I have a few questions based on the shared description: 1) Which database will you use in production—PostgreSQL or MySQL? 2) Do the connection drops happen on specific routes or only under load? 3) Can you share env variables and Alembic revisions for debugging? I can help stabilize your FastAPI platform by diagnosing and fixing the SQL connection failures blocking launch. With 8+ years of experience in FastAPI, SQLAlchemy, and PostgreSQL/MySQL, I’ll provide precise, production-ready corrections. How I Will Help - Review engine, pooling, and session management to stop dropped connections - Fix transaction handling and validate Alembic migrations - Provide commit-ready patches plus a clear setup/report - Suggest quick indexing or query optimisations where valuable Please open the chat so we can continue the conversation! Warm regards, Idefco Note: The price is just a placeholder.

Hi there, I work heavily with FastAPI, SQLAlchemy, PostgreSQL/MySQL and have fixed many production apps that were failing due to bad engine configs, broken pooling, or incorrect session/transaction usage. Connection drops under load are almost always tied to misconfigured pooling, lazy session handling, or migrations not matching the schema — all things I’ve dealt with recently. I can review your repo, trace the exact failure path, stabilise the DB layer, and push clean commit-ready fixes. I’ll also provide a short report explaining what went wrong and how to run the setup reliably in both local and production environments. Happy to jump on a free consultation call before starting. You release the first milestone only after seeing actual progress, and I’m available 24/7 for any urgent support. I’m also open to pointing out quick query/index improvements if I spot them along the way. Let’s get your platform ready for launch.

Hello, I will help you fix your FastAPI course site database issues with precise engineering and a smooth rhythmic touch, restoring your platform to a clean and dependable flow. I will trace the problem to its origin, stabilize the data layer, and bring your course system back into graceful harmony. This includes: 1. Diagnosing database errors, broken relations, ORM misconfigurations, or migration conflicts that may be blocking course creation, enrollment, or content loading. 2. Repairing your FastAPI models, endpoints, and database schemas so every data read and write behaves with calm clarity. 3. Testing all course related workflows to ensure the entire platform from lessons to users to progress tracking operates with steady reliable rhythm. Before we begin: 1. Are you using SQLAlchemy, Tortoise ORM, or another mapping layer for your database structure 2. Would you like me to fix only the immediate database issues or also refine the overall architecture for long term stability Let me know how you would like to proceed, and I will begin tuning your FastAPI course site until it runs with elegant precision and a quiet poetic pulse.
