Leo Frank — AI Systems Builder

把数据、搜索与大模型,构建成可靠运行的 AI 系统。
Building reliable AI systems from data to retrieval, reasoning and production.

Open Source · WebVideoHarbor · GitHub

你好,我是 Leo 👋

我是一名专注于 AI 应用、数据与搜索架构 的资深后端工程师,长期使用 Java、PHP 构建企业级系统,也用 Go 完成独立产品。

我喜欢把复杂业务问题拆解为清晰、可执行、可观测的系统:从数据接入与检索,到 Agent 工作流、大模型推理、流式输出,再到 Trace、重试、降级和生产稳定性。

白天解决复杂系统问题,深夜一点半继续做开源产品。

Currently Building

  • 🧠 Reliable Agent Systems — 结构化 RAG、Context Engineering、多阶段生成与模型治理
  • WebVideoHarbor — 免费、开源、本地运行的网页媒体识别与下载工具
  • 🔎 Data & Search Architecture — 数据同步、CDC、Elasticsearch、PostgreSQL 与复杂查询优化

What I Build

AI Engineering

Agent Workflow · Structured RAG · Context Engineering · Model Routing · SSE · AI Trace

将不确定的大模型能力放进确定性的工程流程:任务拆分、状态管理、结构化校验、有限重试、差异化降级和结果溯源。

Data & Search

Elasticsearch · PostgreSQL · MySQL · Redis · MongoDB · CDC

围绕数据接入、索引构建、复杂检索、聚合分析与最终一致性设计数据链路,并通过预计算、快慢路径和渐进式迁移改善性能与可维护性。

Reliable Backend

Java · PHP · Go · Spring Boot · Laravel · WebFlux · Message Queue

把状态机、失败补偿、超时控制、契约测试、链路追踪和优雅停机作为系统设计的一部分,而不是上线前最后补上的功能。

Featured Work

Open Source · Chrome Extension · Go · macOS

免费、开源、本地运行的网页媒体识别与下载工具。Chrome 扩展负责发现网页向浏览器暴露的媒体,本地助手负责下载、合并分片和保存文件;项目不运营下载中转服务器。

Enterprise AI Analysis Platform

Agent Systems · Structured Data RAG · Reactive Streaming

参与从 0 到 1 建设独立 AI 应用服务,将复杂分析任务拆解为可编排、可并行、可恢复的工作流;覆盖数据召回、上下文装配、多阶段生成、模型访问抽象、SSE 流式响应与生产可观测性。

Data & Search Architecture

Data Integration · CDC · Search · Analytics

围绕标准化数据处理链路、插件化扩展、失败补偿和增量事件分发建设数据平台;在搜索与分析场景中实践分层查询、预计算、快慢路径、索引治理及 Elasticsearch 向 PostgreSQL 的渐进式演进。
