About this gig

Deployment errors on Vercel, Render or Railway fixed. Your app works locally but breaks in production, and I make it work live.


This gig is for the specific hell of an app that runs on your machine and dies on deploy.


ERRORS I HAVE FIXED FOR REAL

- CORS and preflight failures between frontend and API

- Auth cookies dying cross-site (the Secure and SameSite=None trap)

- Page refresh giving 404 because rewrites are missing

- Env vars missing at build time vs runtime

- Free-tier cold starts timing out the first request

- Docker builds that pass locally and fail on the host


STACKS: React, Vue, Next.js, Node, Express, Python, Django, FastAPI, or anything in Docker


WHAT YOU GET

- Your app live on a URL, working

- A short write-up of what was actually wrong

- Config committed so future redeploys keep working


PORTFOLIO: GameVerse runs a React frontend on Vercel and a Dockerised Node API on Render, with cross-site auth cookies and cold-start handling. I migrated it off AWS EC2.


Send me the exact error. I will tell you what is wrong before you order.
