PROFILE

Jan Berčič

Jan contributed to the oasisprotocol/oasis-sdk repository by building a Docker-based development environment and aligning build targets for improved cross-platform compatibility, using Docker, Rust, and GitHub Actions to streamline workflows. Jan modernized developer documentation by migrating to Docusaurus MDX, enhancing authoring and maintenance. In the EVM module, Jan implemented a generic ERC-20 token framework with derive macros and precompile contracts, enabling standard token operations and ecosystem interoperability. Jan also introduced a fuzz testing framework for EVM contract dispatch, leveraging Rust and fuzzing tools to improve robustness. The work demonstrated depth in blockchain development, build systems, and documentation tooling across multiple domains.
