Keep your Windows business software working reliably and improve it as your needs grow.

I fix bugs and add features to existing VB.NET and C# desktop applications, with a focus on business software backed by Microsoft SQL Server. Since 2010, I have developed ERP systems and modules for accounting, inventory, sales, purchasing, payroll, and import management.

What I can help with: • Diagnose and fix application errors and incorrect calculations. • Add screens, validations, features, and business workflows. • Improve SQL queries, stored procedures, and database interactions. • Modify Crystal Reports and resolve reporting issues. • Improve existing Windows Forms interfaces and usability.

How I work: I review your application and requirements, agree on the scope, and make targeted changes while preserving existing business logic. I then test the affected workflows and provide the updated source code, agreed deliverables, and a brief summary of the changes.

To get started, please share: • A description of the issue or enhancement. • Relevant screenshots, error messages, or steps to reproduce the problem. • Your application’s technology and version. • The relevant source code and a database schema or sanitized sample database, where needed.

Please contact me before booking so I can assess the work and confirm the price and delivery timeline.
