Worked on openwrt/packages to enhance Cloudflare DDNS integration by enabling support for custom zone and DNS record IDs, allowing round-robin DNS configurations through param_opt. This involved implementing robust parameter parsing and validation against the Cloudflare API to prevent misconfigurations and improve reliability during dynamic DNS updates. Later, contributed to ggml-org/llama.cpp by addressing a streaming reliability issue, disabling Nginx buffering on streaming endpoints to maintain real-time data flow for downstream consumers such as the Pi coding harness. The work demonstrated proficiency in C++, API integration, DNS management, and backend development, with a focus on reliability and correct system behavior.
