ABOUT ZHENGYU SONG
See what I do here AI Agents for Data Engineering I design autonomous systems that redefine how we interact with data, focusing on:1. Self-Healing & Self-Optimizing Pipelines: Automating pipeline generation, error recovery, and performance tuning to handle schema drift and runtime failures.2. Text-to-SQL Systems: Bridging human language and database logic with semantic layer consistency to enable accurate \"Chat with Data\" experiences.3. Automated Governance & Quality: deploying agents for proactive anomaly detection, PII masking, and data quality enforcement.4. General Agent Lifecycle: End-to-end construction (Google ADK, LangGraph) and rigorous evaluation of general-purpose AI agents. Big Data Engineering Managing large-scale batch and stream processing (Spark, Ray, Daft, Flink, Kafka) and optimizing data lakehouses (Iceberg, Delta Lake) for high throughput and low latency. General Backend Building scalable microservices and event-driven architectures using Java, Spring Boot, Kubernetes, and gRPC.I am driven by the challenge of solving complex infrastructure problems through AI-native solutions.
