I will build scalable backend apis using nestjs and nodejs

I will professionally fix bugs in your NestJS API to ensure smooth, secure, and scalable performance. Whether you're facing issues with routing, DTO validation, JWT authentication, or database integration (MongoDB/Mongoose), Ill diagnose and resolve them with clean architecture and modular best practices. I use TypeScript, Swagger, and class-validator to maintain production-grade quality. Expect detailed error handling, optimized API responses, and recruiter-ready polish. I also offer improvements in middleware, guards, and config setup for deployment. Lets make your backend robust, maintainable, and ready for scale. Share your issue or repo, and Ill get to work with precision and speed.
