I can help writing command-line program in Windows and Linux.

💎 It can be a simple database program using SQLite3.
💎 It can be a simple networking program.
💎 It can be a system or file utility.

The target architecture can be 32-bit or 64-bit.

My primary programming language is FASM, but I can also write C# console app.

A command-line program is a computer program that can work under terminal, for example, under Windows, it is CMD and PowerShell.

I uploaded some of my programs to this forum, you can try search for all topics in Codemaster and Linux & Open Source Software by FlierMate, FlierMate1, MatQuasar.
