Worked on stability and deployment improvements across two open-source projects. For TeamTwilight/twilightforest, addressed a world generation crash by introducing early validation checks for StructureStart objects in Java, reducing crash frequency and improving debugging efficiency in game development workflows. In rafalp/Misago, optimized the Docker image build process by refactoring the Dockerfile to follow best practices, such as replacing ADD with COPY and cleaning up installation artifacts, which enhanced deployment reliability and reduced image size. Demonstrated proficiency in Java, Docker, and Python, focusing on defensive programming and containerization to deliver more robust, maintainable, and reproducible software environments.
