About this gig

Is your site broken, messy on mobile, or not working the way it should?


I will fix bugs, responsive design issues, layout problems, styling errors, broken buttons, forms, menus, spacing, and frontend code problems. I can work with custom builds, HTML, CSS, JavaScript, React, TypeScript, PHP, Liquid, WordPress themes, Shopify themes, and other common web code.


What I can help with:

- Mobile and responsive layout fixes

- HTML, CSS, JavaScript, React, and TypeScript bugs

- Broken buttons, forms, menus, links, and page sections

- Spacing, alignment, typography, and UI polish

- WordPress, Shopify, and custom code cleanup

- Basic speed, browser, and console error checks


Before I start, please send your link, a screenshot or short description of the issue, and any access or source files needed.


For larger issues, full redesigns, backend bugs, API problems, or security work, message me first so I can confirm the scope and recommend the right package.
