Summary
👤
Senior🎓
Top SchoolKaiji Chen is an LLM Algorithm Architect with 12 years of experience building knowledge-graph-driven products and optimizing distributed systems, currently developing an LLM-powered development platform at ByteDance. He holds a Ph.D. in Distributed Database Systems and has led system design and core algorithm development for Huawei’s Knowledge Graph, QA engines, and multimodal LLM applications in consumer products. Kaiji’s background spans research-grade prototyping of data partitioning and query scheduling to production work on ontology construction, concept mining, KBQA and NEL, giving him rare end-to-end fluency from algorithms to product planning. He’s particularly strong at blending data-driven semantic techniques with performance optimizations for large-scale, real-world systems — for example, designing semi-automatic ontology creation and intelligent sharding tools that minimized disruption to CRM platforms. Based in Nanjing, he combines academic rigor with hands-on engineering to translate complex research into deployable, user-facing AI features.
