Expert review for AWS S3 integrations built with Claude Code. We fix Claude Code-generated AWS S3 code for security, error handling & production readiness. From $19.
Common Claude Code issues affecting integrations
Over-permissive CORS configuration
Claude Code sometimes sets CORS to allow all origins during development and forgets to restrict it for production, allowing any website to make API requests.
Missing rate limiting
API endpoints are generated without rate limiting, allowing attackers to brute-force auth endpoints or abuse expensive operations.
Over-engineered abstractions
Claude Code creates multiple layers of abstraction, generic utilities, and design patterns for simple problems — making the code harder to understand and maintain.
AWS S3 issues we find in Claude Code apps
S3 bucket configured with public read/write access
AI-generated code sets the bucket ACL to public-read-write or uses a bucket policy that grants s3:* to everyone, exposing all files and allowing arbitrary uploads.
AWS credentials hardcoded or in client-side code
Generated code includes AWS access key ID and secret access key directly in source files or client-side environment variables instead of using IAM roles or presigned URLs.
File uploads sent through the server instead of presigned URLs
AI tools route all file uploads through your server, creating a bandwidth bottleneck and unnecessary cost, instead of using S3 presigned URLs for direct browser-to-S3 uploads.
