1. AWS Resource Management and Cost Optimization.
2. AWS Technical Support and Solution Design.
3. Design and implementation of K8s platform resource and cost optimization solutions.
4. Design, development, and maintenance of AI agent projects.
Achievement:
1. Proficiently utilizing AI tools such as Codex, GitHub Copilot, Windsurf, Cursor, and Augment Code has significantly improved work efficiency.
2. Independently completed the development of the Resource Efficiency AI Agent from scratch (from 0 to 1), building a full-lifecycle decision-making workflow that encompasses automatic multi-source data aggregation, AI-powered intelligent analysis, and autonomous generation of optimization solutions.
3. By leveraging the MCP, we can seamlessly integrate multi-source heterogeneous data interfaces to enable automatic data retrieval across platforms, data cleansing, standardized aggregation, and data preprocessing—thereby completely eliminating the need for manual data processing.
4. By leveraging core technologies such as RAG, MCP, LangChain, LangFlow, and LangFuse, we build domain-specific knowledge bases and integrate Memory, Skills, and Tool Calling to enable autonomous computation and reasoning.
5. Solution Generation Layer: After the analysis is complete, the Agent automatically generates a structured optimization solution document (containing data references, priority rankings, and expected benefits); the initial draft of the solution is 100% generated by AI, with manual intervention required only for final review and fine-tuning.
