Mikhail developed an automated postinstall build process for the phantom/wallet-sdk repository, focusing on improving developer experience and build reliability. He implemented a Shell-based solution that triggers package builds in topological order immediately after installation, ensuring that all workspace packages are correctly built without manual intervention. This approach resolved issues with missing dist/ folders on fresh clones and eliminated the need for manual build steps, streamlining onboarding for new contributors. By leveraging skills in build automation and package management, Mikhail validated and documented the build order, resulting in more predictable local development workflows and reducing friction for the engineering team.
