Multimodal Interaction Platform Engineer - AI Application Infrastructure Engineer - Backend Platform Engineer - Edge-Cloud and Embodied-AI Application Systems Engineer ## Public Capability Evidence - 平台规模: 4000+ 小区 / 2 万+ 设备 / 50 亿+ 抓拍数据 参与智慧社区数据平台建设，围绕抓拍数据汇聚、解析、统计、转发、展示与运维监控做平台化演进。 - 数据吞吐: 日均 800 万+ 数据吞吐 通过 Kafka 异步流转、补偿机制、缓存治理、查询优化和容器化交付支撑高频数据链路。 - 性能优化: 核心接口约 400ms -> 10ms，聚合查询约 1000ms -> 20ms 基于 Elasticsearch 宽表聚合、Redis 缓存、数据结构调整和冷热数据治理优化查询链路。 - 实时语音链路: 唤醒 / VAD / ASR / LLM / 工具调用 / TTS / 播报闭环 把端侧采音播放、云端模型服务、业务 API 编排和 WebSocket/gRPC 实时通信整合到可运行链路。 - Agent 评测: Function Call 测试集 + EFK 日志 + 人工抽查 关注工具调用准确率、参数识别准确率、失败样例分析和业务动作闭环，而不是只停留在演示效果。 - 端云安全边界: 环境识别 + LLM 语义判断 + 本地雷达/规控校验 机器人和巡逻车任务下发前加入安全门控，避免让 LLM 直接决定具身设备动作。 - Platform Scale: 4,000+ communities / 20,000+ devices / 5B+ capture records Helped evolve a smart-community data platform for capture ingestion, parsing, statistics, forwarding, display, and operations monitoring. - Data Throughput: 8M+ daily data throughput Supported high-frequency data links with Kafka async flow, compensation, cache governance, query optimization, and containerized delivery. - Performance Optimization: Core APIs ~400ms -> 10ms, aggregation queries ~1000ms -> 20ms Optimized query paths with Elasticsearch wide-table aggregation, Redis cache, data-structure tuning, and hot/cold data governance. - Realtime Voice Pipeline: Wake word / VAD / ASR / LLM / tool use / TTS / playback loop Integrated edge capture/playback, cloud model services, business API orchestration, and WebSocket/gRPC realtime communication. - Agent Evaluation: Function Call test sets + EFK logs + human spot checks Focuses on tool-call accuracy, parameter recognition, failure analysis, and business-action closure instead of demo-only effects. - Edge-Cloud Safety Boundary: Environment recognition + LLM semantic judgment + local radar/control checks Adds safety gates before robot and patrol-vehicle task dispatch, avoiding direct LLM-only control over embodied device actions. 边界 / Not the primary positioning: -
