Embedded systems development, primarily in the C programming language. Working deeply with RTOS and file system code.

-Made a 2D game by myself in C++ (https://store.steampowered.com/app/2483300/A_Nest_for_Us/).-Implemented many systems from scratch, including: physics, entity, rendering (using OpenGL), in-game level editing, serialization, and asset management; also designed overall framework.-Ensured systems remained performant (can run at least 144 FPS) using a variety of optimization techniques including: spatial partitioning, SIMD, multi-threading, offline asset preparation, sprite/vertex batching, etc.

Helped to maintain and improve our embedded software suite (Azure RTOS).-Used assembly language and C to add a FIFO mechanism to our RTOS’ (ThreadX) inter-core mutex (before, there was no guarantee of the order the cores would get the mutex in); the FIFO aspect increased determinism within customer applications.-Used Python to automate generation of pointer-sanitization checks for over 100 API function calls for our networking and file system stacks; this allowed users to use those stacks with our modules library.-Created continuous integration testing pipeline on Azure DevOps for modules library, including Win32 simulation of hardware memory protection for testing purposes.

-Helped write tests for company’s USB stack (USBX) until 100% code coverage was met, allowing USB stack to achieve a safety certification.-Performed customer service, directly helping customers online with questions, issues, or requested updates for our suite of embedded software tools.

-Created a linker map file parser in C++ to determine memory footprint of company’s RTOS suite; this information was sent to customers who worked with memory-constrained embedded systems.-Built a Windows desktop app using C++ and Win32 APIs that displayed USB camera data sent from an embedded device via TCP/IP; this app was distributed to clients to demonstrate our USB and TCP/IP stacks.-Ported our GUI demos to over 12 different embedded development boards, using Python scripts to automate the process; these demos were sent to customers.
