Maintenance, bug fixing and performance improvement for your existing web application

I review and fix your web application when it is slowing down, throwing errors or getting harder to maintain as it grows. I work on React, Vue, Next.js, Nuxt.js, .NET (C#) and Node.js projects.

What's included:
• Codebase review and a prioritized issue report
• Finding and fixing the root cause of bugs
• Improvements to rendering, loading and query performance (code splitting, lazy loading, caching strategy)
• Splitting oversized files into a modular structure
• Dependency updates and technical debt cleanup
• Documentation of the changes made

Experience: At Ultia, part of the Turkcell Group, on a 5-year-old no-code platform I resolved render times exceeding 1 minute and led the refactoring program. At Fibabanka I achieved about a 30% improvement in render time and brought the hot reload time down from 2 minutes to instant.

Duration and price: My daily rate is 15,000-20,000 TL. The starting price is for a review and fix round of about 5 working days. We can also make a monthly agreement for long-term maintenance.

What I expect from you: access to the code repository, test/production environment information and a short list of the problems.
