About this gig
Is your website broken on mobile, throwing JavaScript errors in the console, or showing a layout that suddenly fell apart? I will find the cause and repair it fast, with clean code that keeps working.
What I can fix:
- HTML and CSS layout problems (overlapping sections, alignment, spacing)
- Mobile responsive issues on phones or tablets
- JS errors, dead buttons, sliders, menus, popups
- React.js component or UI bugs
- Contact forms that do not send
- Cross-browser display glitches (Chrome, Safari, Firefox, Edge)
Why choose me:
- Clear communication with honest timelines
- You get a short note explaining what went wrong
- No messy hacks, only tested, readable code
- Your files, logins, data stay private
How it works:
1. Share your site link plus a screenshot of the issue
2. My review confirms scope before work starts
3. Each change gets tested across several screen sizes
4. You check everything; revisions are included

FAQ
Which websites do you work on?
Custom HTML/CSS/JavaScript sites, Bootstrap/Tailwind sites, and React.js or Next.js front ends. For page builders, message me first so I can confirm.
What do you need from me?
Your site URL, a short description or screenshot of each issue, and access to the code (GitHub repo, zip file, or hosting/FTP login).
What if you can't fix my problem?
I review the issue before you order. If something turns out to be impossible after the order starts, I tell you right away and you get a full refund.
Will you change my design or content?
No. I only touch the code related to the issues we agreed on, and the rest of your site stays as it is.
