I will fix nestjs and nodejs backend bugs and database issues

Is your application crashing, throwing API errors, or suffering from slow database performance? A broken backend means lost users and revenue. Let a professional handle it.

As a professional backend developer specializing in high-performance microservices architecture, I build, refactor, and fix mission-critical systems to ensure they run smoothly, securely, and efficiently.

What I can do for your system:

Debug and resolve NestJS & Node.js application bugs (TypeScript/JavaScript)

Optimize database queries and schemas for PostgreSQL & MongoDB to handle large datasets

Fix API Gateway routing, gRPC microservice communication, and secure JWT validation guards

Troubleshoot Docker configurations, docker-compose container bugs, and environment setups

Refactor messy backend code into clean, scalable, maintainable architecture

I focus on secure implementations, production-ready performance, and clean code principles. Whether you are facing an API validation roadblock or a complex database architecture issue, I will pinpoint the root cause and resolve it permanently.

Please send a message with your logs or system architecture details before placing an order!
