Senior Ai Developer|Llm Nlp Cv Ml Asr Tts
I am an AI engineer with 10+ years of hands-on experience designing and delivering end-to-end algorithm systems across computer vision, NLP, speech (ASR/TTS), 3D reconstruction and large-scale LLM/agent applications. I have led projects from problem definition and data acquisition through model design, training pipelines, quantization and on-prem deployment. Selected project highlights include medical imaging and 3D reconstruction pipelines, multilingual document RAG systems, multi-role emotional TTS, large-model fine-tuning with quantized local serving, multi-agent orchestration and production automation that connects ASR → RAG → business workflows.

Experience
CTO
Tsinghua Tongfang Japan Co. 2014 - 2025
Lead design and development of AI algorithms and systems across CV, NLP, ASR, TTS, 3D reconstruction, LLMs and Agent-based solutions. Translate client requirements into domain-appropriate technical solutions and project plans. Architect end-to-end pipelines: data collection strategies, annotation schemes, and data preprocessing workflows. Design model architectures, loss functions and evaluation metrics tailored to task and product goals. Implement and maintain robust training pipelines, experiment tracking and hyperparameter tuning processes. Execute model compression and quantization to meet latency and footprint constraints for deployment. Deploy models to production environments and support integration, monitoring and performance optimization. Lead AI POC development to validate feasibility and pave the way for productization. Provide technical guidance and mentorship to cross-functional teams and stakeholders throughout R&D and handoff.
Developer
IBM (Shenzhen) 2009 - 2014
Led development and maintenance of the IBM DB2 database engine and associated components. Designed and implemented core database features, including storage structures, query processing, transaction management, and indexing strategies. Developed and enhanced SQL language support and query optimizer logic to improve correctness and execution efficiency. Managed schema design, version migrations, and backward-compatibility considerations across releases. Implemented and maintained backup/restore, disaster recovery, high-availability (HADR) and replication mechanisms. Applied security hardening, patch releases and access-control policies to ensure compliance and data protection. Built monitoring, logging and alerting solutions for operational visibility and proactive incident detection. Produced technical specifications, design documents, tests, and release notes; maintained CI/CD and build pipelines. Investigated production incidents, performed root-cause analysis, and delivered fixes and performance improvements. Collaborated with QA, support, product management and customers to drive product requirements, troubleshooting and delivery.
