Rockstar🎓
Top SchoolQifang Deng is a quantitative consultant and research fellow with 11 years of engineering experience bridging telecom research, machine learning and embedded systems. He holds a PhD and MSc (distinction) from King’s College London and has worked on xAPP development for 5G O-RAN, ML-driven CU/DU control, and tactile-haptic communications research. At WorldQuant he applies mathematical and ML models to financial prediction, while his open-source contributions to OpenWrt/LEDE show deep hands-on expertise in kernel/networking work for real-world routers and MediaTek platforms. Formerly a data scientist at UCLH, he brings production Python analytics experience alongside low-level BSP and firmware improvements—an unusual combination of high-frequency quantitative modeling and embedded networking systems. Based in London, he blends academic rigor with practical engineering, from RIC servers to energy-efficient Ethernet and MTU/ VLAN fixes in major open-source router projects.
