👋 你好，我是 Rex Fan

我帮助美国医疗团队构建符合 FHIR 标准、可通过审计的互操作系统（基于 .NET）。

🏥 医疗 IT / FHIR 互操作性 · 同时涉猎 💹 量化开发 与 ⚡ 雷电科学

🔬 研究领域

1️⃣ 🏥 美国医疗信息技术 (Healthcare IT)

研究方向： FHIR R4/R5 互操作性、临床数据 ETL 流水线、基于 AI 的语义验证。

  • 开发了 HealthData-Interoperability-Csharp —— 基于 .NET 10 构建的生产级医疗互操作性引擎，实现了符合《21世纪治愈法案》标准的 HL7 FHIR R4/R5 合规性。

2️⃣ 💹 量化交易与金融科技

研究方向： 多源市场数据接入、券商执行系统、实时数据分析。

  • 构建了 Quant.Infra.Net —— 一站式 .NET 量化交易基础设施（Binance/IB/嘉信统一 API、实时预警、投资组合分析）。

3️⃣ ⚡ 雷电科学与技术 (Lightning Science)

研究方向： 闪电定位系统数据分析、雷击密度计算、GIS 可视化。

  • 开发了 LLSDA —— 一个开源跨平台的闪电时空分析类库（已在 NuGet 发布）。
