PROFILE
Sanchit Sahay
Worked on the Lind-Project/lind-wasm repository, delivering core system features and reliability improvements for WebAssembly sandboxing and POSIX compliance. Over seven months, implemented system call interposition, memory management refactors, and a benchmarking framework for system calls and file I/O, using C, Rust, and Python scripting. Enhanced error handling and resource management, stabilized build tooling, and introduced secure validation modes to strengthen type safety. Addressed edge-case bugs in system call handling and improved performance through dispatcher optimizations and efficient random number generation. Expanded test coverage and API stability, enabling robust multi-language workflows and maintainable, high-performance backend development for WASM environments.

Jul 1, 2025July 2025 Lind-wasm monthly summary: No new feature releases in this period; primary focus was stability and robustness improvements in system call handling. A critical edge-case bug was fixed by hardening close_syscall against negative file descriptors and ensuring EBADF is returned instead of panicking. This fix reduces runtime risk for wasm modules invoking system calls with invalid fds and aligns behavior with standard error semantics.
