+Undertook a research project exploring the applicability of RAID-like parity schemes to mitigate common memory vulnerabilities in the context of a hardened memory allocator.
+This involved subdividing a large memory region into many segrageted parity regions, and subdividing those parity regions into 128 KiB blocks such that if any block became corrupted, the corruption could be isolated and recovered from using the parity data from the other blocks in its parity region.
+The allocator also includes custom constant-time comparison algorithms to prevent side-channel timing attacks; an HMAC-SHA256 checksum per block and a CRC32 checksum per allocation to ensure data integrity; aggressive use of mprotect to lock memory from reads and writes unless specifically requested; a custom signal handler to catch SIGSEGV and SIGBUS and trigger recovery without crashing (in development); and a strict tokenized transactional access system, abstracting raw pointers from the consumer code and allowing for easy periodic relocation of allocations.
+This project will culminate in a whitepaper upon completion of the core functionality.

 Built a 2D sprite-based game engine with a custom memory allocator (backed by mmap/VirtualAlloc) and associated profiling and debugging tools.
 The engine supports arbitrary numbers of drawable sprites; multiple types of tilemaps; self-contained game scenes each with their own init, destroy, and update functions; a sound mixer; and a performant particle system. This developed my organizational skills in the context of a larger, cross-platform project of more significant complexity, and gaining confidence debugging using GDB and LLDB to diagnose and fix subtle memory bugs that would appear at runtime, and only under certain specific conditions.
