Worked on the wasmerio/wasmer repository to address a critical build stability issue affecting 32-bit targets. Focused on systems programming and low-level development using Rust, the work involved preventing usize overflow by safely casting the length of an internal map to u64 before comparison. This technical approach resolved a bug that previously caused build failures on 32-bit architectures, ensuring correct behavior and improving cross-platform reliability. The fix enhanced the stability of Wasmer for users deploying in constrained or diverse environments, supporting ongoing portability efforts. Emphasis was placed on robust build systems and commit-based traceability to maintain code quality and reliability.
