Sales Dashboard Full-Stack Development

I need a skilled full-stack developer to build a secure, responsive business dashboard that lets my administrators track and manage customers, leads, and sales from one place. The application should offer clean data entry screens, searchable tables, and visual reports (charts or graphs) so we can spot trends quickly without exporting to spreadsheets.

Core expectations
• Authentication & role-based access strictly for owners/administrators
• CRUD functions for customer, lead, and sales records, with bulk import/export (CSV or XLSX)
• Dynamic filters, sorting, and summary KPIs on a central overview page
• Visual analytics—bar/line charts and simple funnel views rendered client-side
• RESTful (or GraphQL) API so data can later feed a mobile app
• Deployment to a cloud host (Heroku, Vercel, AWS, or similar) with environment variables for secrets

Tech stack is flexible: if you prefer React + Node/Express + Mongo/PostgreSQL, Vue + Laravel, or Django + React, propose what you can deliver efficiently and maintainably.

Acceptance criteria
1. All listed features operate bug-free on the latest Chrome, Firefox, and Edge.
2. Lighthouse performance score ≥ 80 on desktop.
3. Source code in a private Git repo with clear README and setup script.
4. One brief hand-over call or screen-share walkthrough.

If you have a relevant portfolio piece—especially dashboards for customer and sales workflows—share it so I can gauge fit. I’m ready to move quickly once we agree on timeline and milestones.
