Backend .NET Developer | ERP & E-Invoicing Systems

I developed the backend of invoicss.com, a centralized ERP platform for sales invoicing and tax compliance. Businesses create their invoices once, and the system automatically calculates VAT and submits each invoice directly to the relevant national tax authority, so there is no need to log into government portals or re-enter data by hand. It brings the full workflow (invoice creation, tax calculation, validation, submission, and status tracking) into one place and follows each country's required e-invoicing standards.

Tech stack: .NET Core, Entity Framework Core, Dapper, SQL Server, Redis, Serilog, Clean Architecture, SOLID principles, CI/CD, AWS, and Azure.

If you need a reliable, scalable .NET backend, especially for invoicing, finance, or compliance-heavy systems, I'd be glad to help you build it.
