FREQUENTLY ASKED QUESTIONS

Got Questions? We Have Answers.

Can you modernize an aging Windows-based application without a risky full rewrite?

Yes. We specialize in incremental modernization — building modern web/API wrappers, migrating backend data stores to SQL Server, and replacing obsolete modules in phases while keeping daily business operations uninterrupted.

Do we have the freedom to host the application on our own servers?

Absolutely. You can run your .NET application in-house on physical Windows Servers / IIS inside your firewall, or host it in Azure or AWS. You hold complete control and 100% intellectual property ownership.

How do you connect custom applications to our existing ERP or database?

We engineer custom ODBC connectors, REST APIs, and event-driven data sync pipelines that connect securely with ERPs, accounting systems, and SQL databases without corrupting proprietary tables.

Who supports the software after it goes live?

Unlike agencies that outsource development and hand off maintenance to junior rotations, the exact senior engineers who architected and built your codebase handle ongoing maintenance and feature sprints.
