FAQ
What information do you need to fix my bug?
Share a description of the issue, any error messages or screenshots, and access to your codebase (GitHub or similar). The more detail you give, the faster I can fix it.
What technologies do you work with?
React, NextJS, NodeJS, ExpressJS, TypeScript, JavaScript, MongoDB, PostgreSQL, Supabase, REST APIs, Tailwind CSS, and more. If you're unsure, message me with your project details.
What if the fix doesn't work?
I test every fix before delivery. If something isn't right, I'll revise it until it works properly. Your satisfaction matters.
Can you fix WordPress or PHP bugs?
I specialize in JavaScript-based applications (React, NextJS, NodeJS). For WordPress or PHP issues, I'd recommend finding a seller who specializes in those technologies.
How fast can you deliver?
Most single bug fixes are delivered within 24 hours. More complex issues may take 2-3 days. I'll give you a realistic timeline before we start.
