Worked on the kenzok8/sublink-worker repository to enhance reliability and maintainability by addressing configuration management challenges. Focused on backend development using JavaScript, the work included refactoring the KV namespace naming system to separate worker and namespace constants, enabling dynamic name generation for safer, scalable deployments. A duplication-aware fix was implemented to prevent identical proxy entries in Clash configurations, reducing the risk of configuration errors. The approach emphasized constants-driven configuration and dynamic naming strategies, supporting multi-tenant readiness and future extensibility. This work demonstrated skills in DevOps, scripting, and configuration validation, resulting in a more robust and maintainable codebase.
