How quickly can you fix my bug?
Most bugs are fixed within 24-48 hours. For urgent issues, I offer express delivery (12-24 hours) as a gig extra.
Can you fix urgent issues?
Yes — message me for priority delivery.
Can you integrate APIs or connect my frontend to a backend?
Yes! I can connect your React/Next.js frontend to any REST API or develop a backend using Express.js or FastAPI with database support. Just let me know your requirements in advance.
Do you provide backend development too?
Yes. In the Premium package, I offer complete full stack development with backend in Express.js or FastAPI. This includes API development, routing, DB integration, and authentication if needed.

All packages come with revisions, and I offer free 5–7 days of support after delivery for minor updates, bug fixes, or deployment assistance.
Will my code be safe?
Yes — I only work in secure environments and never share code.
