January 2025 — Delivered containerized deployment for the offchain Midgard node in Anastasia-Labs/midgard, establishing reproducible environments and streamlined deployment workflows. Implemented a Dockerfile and a Nix dev flake to enable consistent local development and production parity, laying groundwork for reliable operations. The container image also integrates the Midgard SDK to ensure dependencies are ready at runtime. This work reduces deployment risk, shortens onboarding time for contributors, and improves overall reliability for offchain components.
