Fix Node.js Backend Bugs
Node.js backend crashing? Memory leaking? APIs returning 500 errors? We debug and fix Node.js issues in Express, NestJS, Fastify, and custom Node.js applications.
Need this done for your project?
We implement, you ship. Async, documented, done in days.
Node.js Issues We Fix
- Server crashes — Unhandled promise rejections, uncaught exceptions, out-of-memory kills.
- Memory leaks — Heap growing over time until the process crashes. We use heap snapshots and profiling to find the leak.
- Performance bottlenecks — Slow API endpoints, event loop blocking, database connection pool exhaustion.
- Authentication issues — JWT validation failures, session management bugs, OAuth flow errors.
- Database problems — Prisma/TypeORM query errors, connection timeouts, migration failures, N+1 queries.
- Deployment issues — Docker container crashes, PM2 configuration problems, environment variable issues.
Frameworks We Work With
- Express.js — the most common Node.js framework
- NestJS — enterprise TypeScript framework (our backend uses NestJS)
- Fastify — high-performance alternative to Express
- Hono — lightweight edge-first framework
- Custom Node.js servers
Pricing
- Single Bug Fix — $69: One specific backend bug diagnosed and fixed
- Backend Audit — $249: Full code review, fix all issues, performance optimization
- Ongoing Support — $349/month: Priority fixes, monitoring, architecture guidance
