Payroll and payroll tax processing for US small businesses
ConnectPay Payroll Services runs payroll and tax processing for small businesses, built in-house on a Microsoft-centric stack: C#, .NET Core and VB.NET on Azure, with Angular/NgRx front ends and SignalR for real-time updates. The mix of Tosca, Playwright, xUnit and NUnit points to a mature QA practice, while VB.NET alongside .NET Core hints at legacy code still in service. Current hiring is minimal and sales-focused, run on Zoho CRM and ZoomInfo.
