B2B legacy modernization
Freelance · Confidential client. Next.js, Node.js and PostgreSQL integrated with C# / .NET, preserving full compatibility with a roughly 20-year-old system.
Context
Modernizing a B2B product for a confidential freelance client. The web application coexists with an existing C# / .NET application and a legacy system that is approximately 20 years old.
Engineering work
Next.js, Node.js and PostgreSQL support the web application. The integration preserves full compatibility with the existing system, including workarounds for its specific constraints.
Compatibility is part of the scope: modernization without requiring the legacy application to be replaced before the web product can be used.
The client’s name, screenshots and source code are not published for confidentiality reasons.
