FAQ
Do you need access to my codebase?
Yes, in most cases I'll need to see the relevant Next.js code. You can share via GitHub private repo, a ZIP file, or paste the relevant files in chat. Your Next.js code is never shared, stored, or reused. Confidentiality is guaranteed.
What if you can't fix my Next.js bug?
I won't accept your order if I'm not confident I can solve it. Always message me first with your issue, if it's out of scope, I'll tell you honestly and point you in the right direction at no charge.
What information should I send?
The error message or screenshot, what you expected vs. what actually happens, your Next.js version (run `next --version`), and which page or component is affected. The more context, the faster I solve it.
Do you fix TypeScript errors in Next.js projects?
Yes. TypeScript errors, type conflicts, and ESLint issues inside Next.js and TSX files are fully within scope for all packages.
Can you fix deployment issues on Vercel?
Absolutely. Vercel build failures, environment config errors, and deployment pipeline issues are some of the most common Next.js problems I fix. Netlify and Railway too.
My Next.js bug is complex which package should I order?
Message me first. I'll recommend the right tier honestly. I won't upsell you to a package you don't need.
Do you fix bugs in Next.js App Router (Next.js 13/14/15)?
Yes, I work with both the legacy Pages Router and the modern App Router, including Server Components, Client Components, layouts, loading states, and server actions.
What if the bug comes back after you fix it?
Unlimited revisions means I'm accountable until the fix is solid. If the same Next.js bug reappears after my fix, contact me and I'll resolve it at no extra charge.
Can you work with my existing development team?
Yes. I'm comfortable reviewing pull requests, working within Git workflows, or collaborating via Slack if needed. Just mention this when you message me.
What is your Next.js experience level?
I'm a Senior Frontend Engineer with 4+ years of professional Next.js experience. I was promoted to Frontend Team Lead at Graana.com - Pakistan's largest property platform, after just 8 months. I've shipped Next.js apps across real estate, AI, and enterprise industries
