Qihr focused on backend stability in the kenzok8/sublink-worker repository, addressing a critical connectivity issue affecting Trojan-based proxy scenarios. By implementing robust handling for the Trojan TLS SNI parameter, Qihr ensured that secure TLS connections could be established even when the SNI was omitted, defaulting safely to the host value. This targeted JavaScript fix consolidated TLS parameter logic, reducing failed connections and improving reliability for conversion-service workflows. Drawing on skills in backend and full stack development as well as network configuration, Qihr’s work enhanced proxy stability, lowered operational risk, and contributed to a smoother user experience for Trojan proxy users.
