Worked on the Anastasia-Labs/midgard repository to enhance developer onboarding and streamline the project’s setup process. Developed a Codec Definition Language (CDDL) specification to formally define the data structures and protocols for Midgard blocks and transactions, providing clarity for future contributors. Established a reproducible development environment using Nix, with a focus on LaTeX compatibility to support documentation workflows. Improvements to project documentation and onboarding materials aimed to accelerate contribution cycles and reduce setup friction. The work leveraged DevOps practices, Nix, and CDDL, laying a technical foundation for more efficient collaboration and clearer data structure definitions within the Midgard project.
