Developed a Docker-based development environment for the necst-telescope/necst repository, focusing on containerized infrastructure to support telescope control and observation workflows. Leveraged Docker, Python, and ROS 2 to create reproducible build and run configurations, along with automated scripts that streamline onboarding and reduce environment drift across the team. Integrated a dome-control fix to improve hardware reliability during observations, enhancing the stability of dome operations. Emphasized continuous integration and Git-driven collaboration, enabling faster feature delivery and more efficient setup validation. The work prioritized maintainable documentation and onboarding-friendly processes, resulting in a consistent developer experience and accelerated iteration cycles for new features.
