Fix & Upgrade Legacy Apps | C++/Delphi/Basic/.NET Migration Specialist
I specialize in maintaining and modernizing legacy applications, including Visual FoxPro, Delphi, C++, and older .NET systems. I have hands-on experience with FoxPro programming, database design, SQL, OOP, indexing, and debugging legacy code. I am also experienced with integration technologies such as ODBC, OLE, COM, and REST/JSON, as well as reporting tools like Crystal Reports and Visual FoxPro native reporting. I work independently, communicate clearly in English, and can quickly understand and improve legacy systems.
