Mainly working on the antivirus called VirusBarrier. This requires development skills about- kernel extensions (kext),- Apple's Endpoint Security API introduced with macOS Catalina, - daemons,- concurrency programming (libdispatch),- XPC, User Interface design, Objective C, C++, Swift, yara...AV development activities include among others:- resource load controller in order to prevent VirusBarrier from consuming all the computer resources during full scans. At any times it gives priority to other user processes. This load controller was implemented following techniques used in programmable logic controllers (PLC).- optimization for realtime scanning (minimize impact on overall computer performance)- yara parser (including custom yara rules)- evolutions written in SwiftNewer activities
