About this Gig
Need an experienced developer to review your Node.js or NestJS backend before launch, refactoring or further development?
I will perform a practical code review focused on real production risks, not just formatting.
I can review:
Node.js, NestJS, Express and TypeScript code
Project architecture and module structure
REST API design
Error handling and logging
Authentication and authorization flows
PostgreSQL / MySQL / MongoDB access patterns
Performance and scalability risks
Maintainability and code duplication
Security red flags visible in the source code
Common async, validation and data consistency issues
You will receive a structured report with prioritized findings, severity levels and concrete recommendations.
This Gig is for code review and technical analysis. Code rewriting, large refactoring, penetration testing and complete feature development are not included unless agreed through a custom offer.
Please contact me before ordering for large repositories.
Development technology:
JavaScript
FAQ
What technologies can you review?
My primary stack is Node.js, TypeScript, NestJS and Express. I can also review backend code using PostgreSQL, MySQL, MongoDB, Redis and common API integrations.
Will you modify my code?
The standard service is a review and written report. Small fixes can be ordered as an extra. Larger refactoring or development requires a custom offer.
How will I share the code?
You can provide the source files through Fiverr or give temporary read-only access to a repository when appropriate.
Do you review private repositories?
Yes. Please provide only the minimum access required for the review and revoke access after the order is completed.
Do you perform security audits?
I identify security-related issues that are visible during a code review, but this Gig is not a penetration test or formal security certification.
Can you review an AI-generated or vibe-coded backend?
Yes. I can review AI-generated code for architecture, duplicated logic, unsafe patterns, broken integrations and production readiness.
Can you review a large project?
Yes. Please contact me first with the approximate repository size and the areas you want reviewed so I can prepare a custom offer.
