During February 2026, Luodaoyi developed custom traffic routing features for the kenzok8/sublink-worker repository, focusing on enabling granular routing policies based on source IP CIDR. Using JavaScript and Node.js, Luodaoyi implemented initial support for CIDR-based routing rules, then incrementally enhanced the system to handle protocol-specific logic and robustly process null values. This approach allowed users to define flexible routing behaviors, improving both security and operational resilience. The work was delivered through two well-scoped commits, reflecting a careful, test-driven development process. While the contribution was limited to a single feature, it demonstrated depth in full stack and front end development.
