What you get with this Offer
Most Node.js bugs that "happen randomly" aren't random: an unhandled promise rejection, a missing await, or a race between two requests. I find the actual cause instead of wrapping it in try/catch and hoping.
What you get:
- Diagnosis of the bug with the root cause explained in plain words
- Fix applied and tested, without breaking other routes
- Check of nearby code for the same pattern, so it doesn't come back
- Short note on what changed and why
I work with Express, NestJS, REST and GraphQL APIs, MongoDB, PostgreSQL, MySQL, Supabase, Firebase, authentication (JWT, OAuth), payment webhooks (Stripe) and deployment issues on Vercel, Render, Railway, AWS or VPS.
One bug or one clearly defined issue per offer. If it turns out bigger than expected, I tell you before doing extra work.
