I will fix bugs and debug your backend code

Is your Node.js or Express backend throwing errors, crashing, or behaving unpredictably? I'll dig in, find the root cause, and ship a clean fix rather than a band-aid patch.

I'm a backend developer with 4.5+ years of experience building and maintaining production APIs in Node.js, Express, and NestJS, working with MongoDB, PostgreSQL, MySQL, and Redis. I've debugged issues ranging from broken authentication flows to memory leaks, race conditions, and flaky third-party integrations.

Every package includes a clear diagnosis of what's wrong before I touch your code, so you know exactly what you're paying to fix. Higher tiers add a written root-cause report and a full backend health check covering performance, basic security, and error handling, plus a prioritized roadmap for what to improve next.

Send me your repo or the relevant files along with a description of what's going wrong, and I'll get started. I write clean, well-tested fixes and keep you updated throughout.
