Over deze dienst
Is your website broken, slow, or full of bugs affecting your users and conversions?
Even small bugs can break functionality, reduce performance, and hurt your business.
I help you fix issues quickly and improve your application stability.
I will fix bugs in your Next.js, React, or JavaScript website using AI-assisted debugging and performance optimization techniques.
What you will get
- Fix JavaScript / React / Next.js bugs
- AI-assisted debugging (faster issue detection)
- Performance optimization
- Error fixing (console, API, UI issues)
- Clean and maintainable code
- Responsive fixes
- Debugging complex issues
Why this works:
- Faster debugging = less downtime
- Clean code = fewer future bugs
- Optimized performance = better user experience
Most developers fix symptoms.
I fix root causes.

Lopende samenwerkingThere was a glitch with the design on the expiration box on the last page of the design. Seller told me it was a cache stored in phones browser. I trusted him and gave him the benefit of doubt but after delivery I discovered it was an error in the code. When I tried to contact seller, he made himself unavailable to contact and disappeared.
