Over ** years of Development Experience

408-***-****

I am seeking an opportunity to cooperatively develop capable high value systems and subsystems. Learning is important to me. I am continually learning the work, and I want to do it well. I sought to specialize in distributed and high-speed computing, UI, and systems level work in C & C++. Have kept pace with the latest developments in C++20 as much as I am able.

Experience

March 2021 – Present C++ Engineer, Cipherloc Inc.

•Development of an encryption system on Linux using a Windows reference code base, system is a user mode application that uses a kernel “pass through” method by means of a TUN device for very rapid data pass-through.

•Encrypts at the packet level, if the encryption requires carry (overflows the 4096 byte packet limit for TCP packets a new packet is created to carry the overflow with accompanying check sums and passed on to the endpoint)

•Due to above can be used to encrypt arbitrary protocols between two hosts

•Can encrypt UDP packets as well

•Demonstration application developed using wxWidgets 3.0.5

•OpenSSL and deep socket development on Linux

•C++ for all development using GCC, GDB, Cmake and autotool chain

•Created software packager system to bring up git branches, boot loaders, Designed XML “graph” system (this is a system that only allows modules to and BSP and assemble into a firmware image

•QT QML design and integration

•C++ in Visual Studio, QT Creator, CMake, auto tools

•Python for build automation

•MFC development

•Gtest/Gmock test harnesses for inline test code

•Cmake build system
