I will fix frontend bugs, responsive issues, and UI problems
Jonathan S
About this gig
Is your frontend broken, behaving strangely, or not displaying properly on mobile?
I can help you diagnose and fix frontend issues in existing web applications built with Angular, React, TypeScript, JavaScript, Bootstrap, PrimeNG, and similar technologies.
I have 8+ years of professional web development experience working on production applications, dashboards, fintech platforms, admin systems, API integrations, and responsive interfaces.
I can help with:
- Frontend bugs and runtime errors
- Responsive and mobile layout problems
- HTML/CSS/Bootstrap styling issues
- Angular and React component issues
- TypeScript/JavaScript errors
- Forms and validation problems
- REST API integration issues
- Broken UI behaviour
- Existing dashboard and admin-panel fixes
I focus on clean, reliable fixes that work with your existing codebase rather than unnecessary rewrites.
Please message me before ordering if the issue is complex or you are unsure which package fits your problem.
I'll review the issue and help you choose the right scope.

FAQ
What technologies can you work with?
I primarily work with Angular, React, TypeScript and JavaScript. I also work with Bootstrap, PrimeNG, REST APIs, Node.js and Laravel-backed applications where frontend integration or debugging is required.
Should I contact you before placing an order?
Yes, especially for complex bugs. Send me a brief description of the issue, screenshots/error messages, and relevant project details so I can confirm the appropriate package.
What counts as one bug?
One bug is one clearly defined issue, such as a broken component, layout problem, form error, responsive issue, or specific frontend behaviour. Multiple unrelated problems may require the Standard or Premium package.
Can you work on an existing project?
Yes. This Gig is specifically designed for existing applications. I can review your current codebase and make targeted fixes without rebuilding the entire project.
Can you fix backend or API-related problems too?
I can handle frontend/API integration problems and some Node.js or Laravel-related issues. If the problem is primarily backend-related, please message me first so I can assess the scope.
