Developed a reproducible development workflow for the vacp2p/nim-libp2p repository, focusing on streamlining onboarding and minimizing environment inconsistencies. Introduced a Nix-based setup by implementing flake.nix and flake.lock, which standardized the use of Nim, Nimble, and OpenSSL across both local and CI environments. This approach ensured that all contributors could work within a consistent development shell, reducing setup friction and environment drift. The README was updated to provide clear usage instructions, further supporting ease of adoption. The work demonstrated practical application of CI/CD, DevOps, and Nix skills, delivering a foundational feature to improve project maintainability.
