FAQ
Which platforms and frameworks do you work with?
I support mobile apps built with React Native (iOS & Android) and web apps built with React.js and Next.js. This includes handling SSR (Server-Side Rendering) for Next.js sites and optimizing both mobile and web performance.
What types of bugs and issues can you fix?
Anything from app crashes, build errors, red/white screens, to API integration problems. I also fix Next.js SSR/SSG errors, routing issues, bundler errors, push notification & Firebase bugs, and more. If it's a React/React Native/Next.js issue, I’ll tackle it!
How fast can you resolve my issue?
I aim for a quick turnaround — most bugs are fixed within 24-48 hours. If you have a tight deadline, let me know and I'll prioritize your project to get it done ASAP.
What should I provide when ordering?
Please share relevant error messages, logs, and any code snippets that reproduce the issue. Access to your code repository (e.g., GitHub) or the project source will help me identify and fix the bug faster.
How will I receive the fixes?
You'll get the repaired code (as a GitHub PR or diff) along with comments explaining changes. I provide tested builds (IPA/APK or web) and a short Loom video walkthrough covering the fixes and improvements.
What if the bug isn’t fixed?
No fix = no payment. I offer a 100% resolution guarantee or full refund. If I can't solve your issue, you pay nothing — your satisfaction is fully assured.
Do you assist with app deployment and store submission?
Yes. I handle App Store and Google Play submission problems, as well as deploying Next.js web apps to platforms like Vercel, Netlify, or AWS. I'll ensure your app gets published smoothly.
Will my app break after your fix?
Not at all. I rigorously test all fixes on actual devices and browsers. My solutions are clean and production-ready, so your app will remain stable and bug-free after my work.
Can you improve performance?
Absolutely. I can optimize load times, reduce bundle sizes, improve code performance, and fix any SEO/SSR issues so that your React or Next.js app runs faster and scores better on performance audits.
Who do you typically work with?
I serve clients worldwide — from small startups and SaaS companies to digital agencies and large enterprises. No matter your industry, I’ll provide professional support tailored to your needs.
