Next.js Feedback System Enhancement

I have already built a full-stack customer feedback platform with Next.js for the front end and PostgreSQL on the back end. The core modules—admin dashboard, customer and branch management, QR-code feedback capture, analytics, and a responsive layout—are in place. Before I launch commercially, I want a seasoned developer to run a deep review, tighten anything fragile, and polish the product experience.

Priority focus
The first area I want you to examine is the reports, dashboard, and overall user experience. Business owners, branch managers, and our own support teams will all rely on this interface, so it must be rock-solid and immediately intuitive. I’m aiming for:
• Clearer charts with easy-to-read summaries
• More granular filters plus downloadable reports (CSV/PDF)
• A smoother mobile layout with simpler navigation

Scope of work
– Audit the existing Next.js codebase and PostgreSQL schema for reliability, performance, and security gaps.
– Refactor or replace any brittle logic you find, especially around data aggregation and chart rendering.
– Implement the dashboard enhancements listed above, preferably with a modern charting library (Recharts, Chart.js, or similar).
– Optimise API calls and database queries so large data sets load quickly on both desktop and mobile.
– Advise on additional best-practice steps (testing, CI/CD, monitoring) that will prepare the system for paid customers.

Deliverables
1. Reviewed and updated source code in a private Git repository
2. A brief technical report summarising issues found, fixes applied, and recommendations for future scaling
3. A demo deployment (Vercel or similar) that reflects the new dashboard experience
4. Documentation for setup, environment variables, and any new scripts

Please let me know:
• Relevant projects or portfolios that demonstrate your Next.js + PostgreSQL expertise
• Your estimated cost and milestone breakdown
• A realistic timeline to complete the review, fixes, and feature upgrades

I’m ready to start as soon as I find the right partner and will be available for quick feedback all the way through.
