Hello, SLOW API & EXECUTION BOTTLENECK When existing backend code grows without clear API layering, performance drops quickly—slow response times, blocking logic, and hard-to-scale endpoints. Migrating to FastAPI without a clean refactor often makes things worse instead of faster. FASTAPI-FIRST OPTIMIZATION APPROACH I will first review your current code to identify execution bottlenecks, blocking calls, and inefficient logic. Then I’ll refactor the core flow and rebuild the API layer using FastAPI with proper async support, clean routing, and structured request/response models. The focus will be on measurable speed gains: optimized execution paths, lightweight API layers, and clear separation between business logic and endpoints. I’ll keep changes minimal but effective so everything is completed within the short timeline. I’m available to start immediately, can work in Vietnam business hours, and will deliver a working, faster FastAPI-based API by tomorrow as requested. FASTER, CLEANER API DELIVERY You’ll get an improved codebase, FastAPI endpoints with better execution time, and a backend that is easier to extend and maintain—without overengineering. The result is visibly faster responses and a cleaner API structure within your $100 budget and tight deadline. Thank you.

Hey — saw your post about needing a Vietnam FastAPI Python developer for a few hours to improve your current code and add API layers. Short “few hour” tasks like this often get messy when the existing codebase isn’t structured well for new endpoints (auth, validation, and error handling usually get skipped). Quick question before I suggest how I’d tackle it: Is your current FastAPI project already using Pydantic models and dependency injection, or is it more of a simple script-style setup right now? I’ve worked on multiple FastAPI projects where I had to refactor existing code and layer clean, documented APIs on top without breaking what’s already in production. If you can send your repo link or a small snippet/spec of the current endpoints you want improved, I can review and tell you what’s realistic in a few hours.

@thangp14

Hi, thanks for the details. The task is clear: improving your existing code, adding API layers, and converting it to FastAPI for better execution speed. The focus would be on keeping the current functionality intact while refactoring for performance, structuring APIs cleanly, and ensuring endpoints respond efficiently. A practical approach is to analyse the existing code, identify bottlenecks, implement FastAPI with optimized routing and async handling where needed, and test all endpoints to confirm faster, stable execution. Deliverables would include the updated code and fully working APIs ready for immediate use. Work can be scoped to finish within your timeframe while keeping the code maintainable for future updates.
