You will get fast, reliable Next.js and React bug fixes
Project details
Is your Next.js or React application showing errors, broken layouts, API failures, authentication problems, or unexpected behavior?
I will investigate the issue, reproduce it, identify the root cause, and implement a focused fix without making unnecessary changes to unrelated parts of your application.
I can help with:
• React component, state, and rendering errors
• Next.js client/server and routing issues
• Responsive layout and cross-browser bugs
• Forms, validation, and API integration problems
• Authentication and Supabase-related issues
• TypeScript errors and dependency conflicts
• Performance problems caused by application code
You will receive the corrected code, testing of the affected functionality, and a clear explanation of what caused the issue and how it was resolved. Documentation and detailed comments are included according to the selected package.
Please contact me before ordering when the cause is unknown, the application has several unrelated errors, or production access may be required. Each package covers the defined scope shown in the pricing section; new or unrelated issues are treated separately.

About Muhammad
Full-Stack Next.js Developer | Web Apps, Dashboards & Flutter
Multan, Pakistan - 5:57 am local time
Recently, I delivered an integrated platform for Bahria Food Street consisting of a Next.js website, Flutter mobile application, and centralized admin panel. The system allows administrators to manage menus, hero banners, advertisement posters and customer-facing content, review financial information, update order statuses, print food receipts, and synchronize data between the website and mobile application through APIs and real-time server sockets.
I also developed a lead-management platform for Leuaora Hotels in a five-day engagement. Hotel staff can create, assign, reassign and update leads, maintain communication logs, record follow-ups, track ownership, and view the complete interaction history for each potential customer.
Other systems I have worked on include:
• An aviation operations portal with role-based dashboards, reporting workflows, document management, recruitment tracking, notifications and live aviation data
• Hotel booking and internal management systems
• Admin dashboards with authentication and role-based access control
• Docker and Ubuntu VPS deployments, SSL configuration and production migrations
• Flutter applications connected to existing web platforms through REST APIs
My main areas of work are:
• Next.js and React web applications
• Admin panels, internal tools and CRM systems
• Node.js, REST APIs and third-party integrations
• Authentication, RBAC, Supabase and MySQL
• Flutter mobile application development
• Docker/VPS deployment and production troubleshooting
My development process is practical: first I understand the business workflow, then define the smallest useful version, divide the work into clear milestones, and provide regular working updates throughout development. Share your existing system, requirements, design, or even a rough idea. I will explain the practical technical approach, what should be built first, and what can wait until a later phase.
