I will fix your nextjs react node python or deployment error
Raul
About this gig
Stuck with a broken build, failed deploy, TypeScript error, API bug, or launch blocker? I help founders and small teams get Next.js, React, Node.js, Python FastAPI, Supabase, Vercel, Railway, dashboards, and automation moving again.
I can help with:
- Reproducing and diagnosing build, deploy, runtime, API, or environment errors
- - Fixing a clear frontend, backend, database, script, or automation blocker
- - Cleaning up smoke checks, launch scripts, and handoff notes
- - Explaining changed files, commands run, and validation results
How it works:
Send the exact problem, app link or repo access, logs, and steps to reproduce. I inspect the issue, apply the smallest useful fix inside the agreed package, run relevant validation, and explain what changed.
Important:
I do not do unpaid test work, handle private secrets directly in chat, or make production, payment, or database changes without explicit approval. If the issue is larger than scoped, I stop and show options before expanding.

I build and fix practical web apps for founders and small teams: AI/SaaS MVPs, dashboards, automation scripts, launch checks, and deployment cleanup. I work with Next.js, React, TypeScript, Python, FastAPI, Supabase, PostgreSQL, Playwright, and PowerShell. My focus is simple: inspect the real project state, fix the highest-impact blocker, add repeatable checks, and leave clear setup/runbook notes so you can keep moving after delivery.
FAQ
What do you need from me before starting?
Please send the exact error, app link or repo access, deployment logs, steps to reproduce, expected result, and relevant env variable names with secret values removed.
Can you fix Vercel, Railway, Supabase, or FastAPI issues?
Yes. I can diagnose and fix build, deploy, API, database migration, environment, auth flow, and smoke test blockers when the scope is clear.
Is this for a full app build?
No. This gig is for diagnosis, blocker fixes, and launch cleanup. If you need a full MVP, we can define a separate fixed scope after the first diagnosis.
Will you work with production data or secrets?
Only with explicit approval and safe handling. Please remove secret values from logs. For risky production, payment, or database changes, I will confirm before acting.
