I will fix next js bugs build errors and vercel deployment
Vasyl P.
Level 1
About this gig
Is your Next.js app failing to build, crashing in production, or working locally but not on Vercel?
I will diagnose and fix a clearly defined issue in an existing Next.js, React, or TypeScript application. I focus on the root cause, a clean production-ready fix, verification of the affected flow, and a concise handoff summary.
I can help with:
- Next.js build and runtime errors
- Vercel deployment failures
- hydration and Server or Client Component issues
- TypeScript and dependency errors
- broken React components, hooks, forms, and state
- App Router, routing, middleware, and API route bugs
- environment variables and production configuration
- 404, 500, blank-screen, and production-only failures
My process:
- Reproduce and isolate the issue
- Confirm the agreed scope
- Implement a clean fix
- Test the affected flow
- Deliver the code and completion notes
Each package covers only its stated scope. New features, redesigns, large refactors, migrations, hacked websites, third-party outages, and unrelated bugs are not included.
Please message me before ordering with the error, logs, reproduction steps, expected result, stack, and deployment URL.

I help SaaS founders and product teams build, fix and finish Next.js and NestJS applications. My focus is existing production codebases: bugs, unfinished features, TypeScript APIs, Stripe billing, authentication, databases, deployment and practical AI integrations. Clients value my communication, attention to detail and work across multiple delivery phases. I define scope before coding, reduce regression risk and leave the codebase easier to maintain. Share the issue, repository context and desired result, and I’ll recommend a fixed scope, milestones or an hourly approach.

FAQ
What counts as one small bug?
One isolated, reproducible issue with a clear expected result, affecting one page, component, or build step. If multiple systems or unrelated symptoms are involved, I will recommend Standard, Premium, or a Custom Offer.
Should I message you before ordering?
Yes. Send the error, logs, reproduction steps, expected result, project stack, and deployment URL. I will review the information and recommend the correct package before you place the order.
What access will you need?
I normally need temporary GitHub or GitLab collaborator access, or a complete ZIP archive. For deployment issues, I may also need temporary Vercel collaborator access. Never send personal passwords or secret keys.
Can you fix an app that works locally but fails on Vercel?
Yes. I can investigate build logs, environment configuration, dependencies, routing, API routes, runtime compatibility, and other production-only differences within the agreed scope.
Can you fix hydration and Server Component errors?
Yes. I work with Next.js App Router and Pages Router issues, including hydration mismatches, Server and Client Component boundaries, rendering, routing, middleware, and data-fetching problems.
What if the issue is larger than the selected package?
I will explain what was discovered before expanding the work. We can add an Extra, extend the delivery time, or use a separate Custom Offer. I will not silently change the price or scope.
What does a revision include?
A revision is an adjustment to the agreed fix when the original reported issue does not meet the agreed acceptance criteria. It does not include a new feature, unrelated bug, redesign, or requirement added after ordering.
Can you guarantee that every bug is fixable?
No responsible developer can guarantee that before reviewing the code, logs, dependencies, access, and third-party services. I guarantee a professional investigation, honest communication, and delivery of the agreed work.
Do you add new features in this Gig?
No. This Gig is for repairing an existing issue. New pages, workflows, integrations, Stripe billing, AI features, large refactors, and application development require a separate scope or another Gig.
What will I receive after the fix?
You receive the corrected source code or repository commit, verification of the affected flow, and a concise summary of the root cause and changes. I also include 3 days of support for the same reported issue.
