Senior .NET / Angular Fullstack Engineer
A large client from Switzerland in the accounting and payroll domain wanted to increase its revenue and support more clients by delivering a more solid, robust and scalable platform to support its clients.
  • Streamlined the client onboarding process for small to midsize businesses, by designing a custom recommendation engine for selecting both fixed price and recurring services using .NET 8 and by integrating with an in-house backend framework which generates the Angular based UI.
  • Successfully improved report generation for Swiss tax purposes, by extending existing modules to support financial statements, balance sheets and assembly protocol documents using Aspose .NET libraries and by increasing compatibility based on the latest fiscal requirements using .NET 8.
  • Increased the stability of the whole platform, by making sure invoice calculations work as expected and by writing unit tests for the billing, pricing and report generation using xUnit.
  • With invoices there were also some issues which actually added 100+ lines to each invoice, here I was able to fix the issue after investing it for a couple of days, and this showed like we were charging the end client more.
