I will do web app development for fintech and business systems

You need a real web application or fintech system, not a theme, spreadsheet, or disconnected set of tools.

I do web app development for business and fintech systems in C# and ASP.NET Core with SQL Server: roles, dashboards, workflows, REST web API development, third-party API integration, and mobile app backends. Deploy on IIS, Azure, or AWS using your account.

What you get:

- Custom web app or fintech application

- REST APIs for web and mobile clients

- Third-party API integration (payments, KYC, SMS, CRM)

- SQL Server, roles, and admin tools

- Excel, CSV, JSON, or API data workflows

- Source code and deployment notes

This is end-to-end custom software. Custom develop web application with long-term enhancements; this gig builds the web app, APIs, and data layer mobile apps need. You own the code. Hosting and vendor fees stay with you.

Message me the users, workflows, and APIs to connect. I will confirm the web app development scope before you order.
