You will get frontend backend bugs fixed and website speed optimized
Project details
Hello! If your website is experiencing bugs, layout issues on mobile, API errors, or slow loading times, I would be glad to help you resolve them.
I am a developer working with modern frontend and backend technologies. I take time to carefully inspect errors, find the root cause, and apply clean fixes without disrupting your existing features.
Areas I can help you with:
• Frontend issues: Fixing CSS layout bugs, Tailwind/Bootstrap styling, and mobile responsiveness
• JavaScript & Frameworks: Resolving errors in React.js, Vue 3, and vanilla JavaScript
• Backend & APIs: Debugging Node.js, Express, NestJS endpoints, and database queries (PostgreSQL/MySQL)
• Speed optimization: Improving loading performance by optimizing assets, scripts, and basic caching
• Deployment: Helping troubleshoot basic deployment issues on Vercel, Netlify, or VPS
My approach:
• Careful investigation of the problem before making changes
• Clean, well-organized code that is easy to maintain
• Honest communication and testing before delivery
Please feel free to message me with details about your issue before ordering so we can discuss if I am the right fit for your project. I look forward to helping you!
