I build data platforms and local AI tools, with a focus on real-time risk processing and AI-driven data understanding. My direction is reliable Agent Infrastructure: systems with clear state, recovery, and action boundaries.
What I do
Distributed Systems Engineering
State, recovery, and observability for data systems, supported by hands-on GitOps platform work.
Real-Time Data Processing & Risk Control
Kafka and Flink pipelines, with real-time risk control as a focus for further development.
AI-Driven Data Processing
Local knowledge retrieval, model-assisted understanding, and controlled actions through CoHelper.
