Rockstar

Josh Watson is a seasoned software engineer based in California with 12 years of experience focused on reverse engineering and vulnerability research. He is an active open-source contributor to core security tooling, notably improving Binary Ninja's Python API and hardening EVM disassembly in ethersplay. His contributions span bug fixes, API enhancements, type safety and robustness improvements—work that reduces runtime errors and improves analysis fidelity for binary and bytecode researchers. Josh combines deep low-level expertise with pragmatic backend development, and often surfaces non-obvious edge-case fixes (like index error guards and hashing for symbolic variables) that materially improve tool reliability.

EVM dissassembler

Role in this project:

Back-end Developer

Contributions:75 commits, 14 PRs, 48 pushes in 11 months

Contributions summary:Josh made several contributions to the EVM disassembler, ethersplay, focusing on core functionality and analysis. Their work included refactoring analysis completion events and background tasks, removing redundant checks, and updating test files. The user also improved the codebase by changing comments to symbols and cleaning up code. They implemented a method for identifying the hash values and linking them to methods within the disassembled bytecode.

Public API, examples, documentation and issues for Binary Ninja

Role in this project:

Back-end Developer

Contributions:1 review, 34 commits, 29 PRs in 4 years 6 months

Contributions summary:Josh primarily contributed to the Binary Ninja API by fixing bugs and adding new features to the Python API. They implemented a flags parameter to the sign_extend function and fixed an issue in BinaryView.get_view_of_file for bndb files. Furthermore, the user added type checks to ssa functions, added the __hash__ method to function, Variable and SSAVariable class. They also fixed possible `IndexError` in `Function.get_*_at` methods.
