• Architected NSD (Network Security Director), an AI-enhanced network traffic security framework in Golang. • Built ByteIDS, a Zeek-based network monitoring system; integrated it into the NTA (Network Traffic Analysis) pipeline with a log streamer publishing to Kafka and persisting data in Elasticsearch and Hive. • Embedded an LLM-driven noise reduction module in NTA using LLaMA-Factory and LoRA; fine-tuned on 20,000 logs to achieve 99%+ recognition accuracy, consolidating 150,000+ hourly alerts into actionable cases. • Developed a scalable alert processor to route high-volume NTA alerts via Kafka to NSD for downstream processing. • Developed Thrift (Kitex) APIs enabling sub-second queries over 30-day historical logs in Elasticsearch.
• Developed the armi-test-tool, an automated testing framework in Python for the 5G Operation Administration and Maintenance (OAM) system. Performed API and web testing leveraging NETCONF protocol, paramiko and selenium libraries, reducing test workload by 60%. • Maintain lab test environment, execute daily regression tests and bug tracking based on Robot Framework scripts. • Set up a CI/CD procedure using Jenkins, enabling delivery of auto test results via email notifications.
• Co-developed an efficient speech extraction system with multi-channel inputs and Direction of Arrival(DOA) information that worked in low SNR environments. • Co-designed a novel UNet architecture utilizing CBAM (Convolutional Block Attention Module) and self-attention. • Implemented Parameterization of Hypercomplex Multiplications(PHM) Layers to reconstruct BiLSTM and reduce 74.7% of its parameters, resulting in a 30.5% reduction in final model size for broader applicability. • Plotted and analyzed experimental data to examine the relationship between model performance and angular resolution.
• Rewrote meson-twitter-connector app based on Node.js and Express.js, adding authentication module to make it compatible with the Twitter OAuth 2.0 authentication flow. • Designed and built the MesonFi Discord Bot using javaScript, automatically processing user-initiated ticket information and handling premium membership verification, reducing customer service workload by 75%. • Developed Meson Telegram Bots in javaScript, used MongoDB to store account information, enabling swift stablecoin cross-chain transactions and status queries, increasing partnership inquiries on Telegram by 55%.
