Performance for your Devin-built FastAPI app
Expert performance for FastAPI apps built with Devin. We audit Devin-generated FastAPI code for performance issues. From $19.
Devin issues we find in FastAPI projects
Problems specific to Devin's code generation patterns when building FastAPI apps.
Autonomous security decisions
Devin makes security-related decisions without human review — choosing auth strategies, setting permissions, and configuring access controls that may be inadequate.
Compounding architectural errors
When Devin makes an early architectural mistake, it builds subsequent features on top of it. By the time you notice, the issue is deeply embedded in the codebase.
Workarounds instead of fixes
When Devin encounters an error, it sometimes adds workarounds that mask the root cause rather than fixing the underlying issue.
FastAPI performance issues we check for
Performance-specific FastAPI problems that need attention before production.
Blocking calls inside async endpoints
Synchronous database calls, file operations, or HTTP requests inside async def endpoints block the entire event loop, making your API unresponsive under load.
No rate limiting on public endpoints
Public API endpoints (especially AI wrapper endpoints that call OpenAI or similar) have no rate limiting, so a single user can run up massive costs.
Database connections not pooled
Creating a new database connection on every request instead of using a connection pool, causing connection exhaustion under load.
