I will fix react, next js bugs, optimize web performance, and refactor code
Golam Rafi
About this gig
Is your React or Next.js site acting up, running slow, or breaking on mobile devices?
Hey there! I'm Golam, a frontend software engineer who loves turning clunky, buggy web apps into fast, clean, and responsive experiences.
Whether you've run into a frustrating state management bug, a broken layout, slow load times, or a codebase that's just turned into messy spaghetti, Im here to fix it right the first time. No quick hacks or band-aid solutions just clean, well-structured, production-ready code.
What I can fix or optimize for you:
- Hidden React/Next.js bugs, API errors, and broken state
- Layout glitches, CSS/Tailwind responsiveness, and cross-browser issues
- Slow page loads, re-render bottlenecks, and poor Lighthouse scores
- Code cleanup: refactoring messy code or upgrading JavaScript to clean TypeScript
Shoot me a message with what's going wrong or link your repo before ordering. Let's get your web app running smoothly!

FAQ
What do you need from me to get started?
I'll need a brief description of the issue (or steps to reproduce the bug) and temporary access to your codebase—such as a GitHub/GitLab repository link or access to a development/staging environment.
Do you work with TypeScript codebases?
Absolutely! I work extensively with TypeScript and can resolve type errors, fix broken interfaces, or refactor your existing JavaScript files into clean, strictly-typed React components.
How do we handle complex or hard-to-reproduce bugs?
Please drop me a message before ordering! We can discuss the exact symptoms or jump on a quick review of your setup so I can give you an accurate time and cost estimate.
What if the bug comes back after you deliver the work?
Your peace of mind comes first. If any issue reoccurs or breaks directly because of the code I touched, I will fix it promptly for free as part of post-delivery support.
