ASP.NET Core Web App Development

I’m building a C# web application in ASP.NET Core and I’m looking for an experienced developer who can jump in and accelerate the remaining work. The project centres on three pillars: solid user authentication, clear and responsive data visualisation, and reliable third-party API integration.

Where I am now: the solution skeleton and basic routing are in place, but the heavy lifting on identity management, charting dashboards, and the external API logic still has to be completed and wired together cleanly.

What I need from you:
• Implement secure registration, login, and role-based access using ASP.NET Core Identity (or another approach you recommend, as long as it stays within the framework).
• Build interactive charts/graphs that pull data from my existing EF Core models; I’m open to your preferred library—Chart.js, Highcharts, or any option that works smoothly with Razor.
• Create and document the service layer that calls the external API, persists responses to SQL Server, and surfaces them to the UI.

Acceptance will be based on:
1. Clean, well-commented code that follows standard ASP.NET Core conventions.
2. A working demo showing sign-up / sign-in, live charts, and successful API calls.
3. Brief hand-off notes so I can maintain or extend the app myself.

If this sounds like your wheelhouse, let’s talk and set up a short technical walkthrough of the current repository so you can estimate effort and timelines accurately.
