Over a three-month period, Mrshnja contributed to the tschneidereit/wasm-micro-runtime repository, focusing on enhancing WebAssembly interpreter reliability and platform compatibility. They implemented V128 support for the WASM_OP_TEE_LOCAL instruction, enabling correct handling of SIMD vector types and expanding test coverage to ensure compliance with WebAssembly specifications. Addressing platform-specific challenges, Mrshnja delivered a targeted fix to prevent unsafe text-section relocations on Android, improving runtime stability. Their work involved C programming, embedded systems, and low-level interpreter development, with careful attention to data flow, reference management, and macro-based platform checks, resulting in more robust and standards-aligned WebAssembly execution across environments.

Aug 1, 2025August 2025: Focused on platform reliability and correctness for wasm-micro-runtime. Delivered a targeted Android relocation safety fix to prevent applying relocations to the text section in indirect mode on Android. The change adds Android to the restricted platforms via a macro check, with commit 9ee44bf2d07681af912bc5cc9bc13ccbfd071969 for traceability. Impact includes improved Android runtime stability, fewer platform-specific relocation failures, and strengthened cross-platform behavior. Technologies demonstrated include platform-specific macro guards, indirect-mode relocation handling, and thorough commit-level traceability.
