Over deze dienst

Is your Node.js or Express app throwing errors, crashing in production, or returning broken API responses? I find the root cause and fix it permanently - not a quick patch that breaks again tomorrow.

I'm a MERN stack developer with hands-on experience building and debugging full-stack Node.js and Express.js applications, including authentication flows, REST API pipelines, MongoDB/MySQL integrations, and React-to-Node communication.

What I fix and build:

Node.js / Express.js crashes and runtime errors

REST API errors - CORS issues, 401/403 auth failures, broken endpoints

JWT, session, and OAuth authentication bugs

Fast delivery, clear communication, and realistic timelines
