  • 与组织内的多个团队合作，确定传输数据时的性能瓶颈，并提出解决这些瓶颈的技术解决方案.
  • 监视应用程序仪表板，以识别任何异常活动或新的错误类型，并提醒相关团队采取行动纠正问题.

Senior Software Engineer

2019 - 2022
NLogic
  • Wrote, debugged, 维护T-SQL服务器表和存储过程以满足业务需求. Also integrated Dapper to the .Net Core data layer project to execute these stored procedures easily.
  • 通过研究和找出最适合我们目的的工具，并在许多场合创建POC模型，为体系结构设计做出了贡献. The tools I recommended include SelectPdf and PrimeNG.
  • Integrated SelectPdf to generate pdf reports from ASP.NET Razor views. This was particularly challenging since debugging pdf is next to impossible. 为了理解和解决工具内部的问题，开箱即用的思维是必要的.
  • Developed a self-guided wizard for creating a dashboard. The front end was done using Angular, and the back end using .Net Core. The database was a SQL server, and T-SQL was used for developing stored procedures.
  • Implemented a feature for importing XML files from third-party systems, 允许用户上传一批文件并动态修复几个验证错误. 如果成功上传，将触发使用Azure持久函数的ETL进程.
  • Developed the database model for the file import process using SQL Server. T-SQL用于开发表结构和存储过程的脚本.
  • 通过从WCF转移到内置的HttpClient特性，纠正了一个长期回避的生产问题 .NET Core, thus reducing the number of concurrent server-to-server connections. This involved taking advantage of the shared connection pool.
  • 将ESLint和Prettier集成到我们的一个绿地项目中，以强制执行编码标准并捕获开发过程中的潜在错误. 这也被添加到CI过程中，以确保所推送的代码具有最好的质量.
  • Developed a custom date range control by extending Angular Material datepicker. This was due to the business's specific requirements, which needed certain dates to be blocked for selection.

Software Engineer

2012 - 2019
Rckr Software
  • 领导一个由四名初级工程师组成的团队，根据特定客户的要求定制GetReal Health的EMR平台. 这项工作包括集成健康信息交换(HIE)和协调XML文件.
  • 监督与客户相关的产品特性的设计、开发和部署. This involved continuously communicating with the client to clarify requirements, guiding junior engineers, and reviewing their code.
  • Contributed significantly to the complete migration of the product from ASP.NET to Angular/.NET Core/ T-SQL stack. 这包括数小时的研究，以找到处理应用程序复杂和动态结构的理想方法.
  • Added tables, views, indexes, 和存储过程到SQL Server数据库，相应的T-SQL脚本到代码库, 哪些与产品的增强有关，哪些是与第三方系统集成所必需的.
  • Incorporated single sign-on using OAuth 2.0 standards in a highly configurable manner. 通过向JSON配置文件中添加端点，可以添加新的身份验证提供程序.
  • 开发了一个消息传递功能，使患者和提供者能够相互交流. 这类似于现代聊天应用程序的实时加载和新消息通知，而无需用户重新加载页面.
  • 创建了一个XSLT，用于将从Microsoft HealthVault等第三方端点访问的XML健康数据与我们的自定义数据类型协调起来. Over 100 data types had a separate structure and needed to be handled individually.
  • 集成健康信息交换(HIE)与我们的核心产品，以促进患者自动登录和导入他们的健康数据到我们的数据库. SQL server was used for storing the mapping data, and T-SQL was used for scripts.
  • 发现了现有单点登录过程的一个主要安全漏洞，潜在的黑客可以修改发送到后端的JSON Web Token来冒充用户. This helped the company securely rectify the issue in time for release.

Trending Stock Charts

一个网络应用程序，方便管理员用户上传趋势股票和其他商品的图表. End users can subscribe to the app and access these charts. This was my friend's business idea that I implemented from scratch. I used Angular for the UI components, .NET Core for the API endpoints, and SQL Server for the database. 我的任务是实现最初的原型，并提供一个条款，以便稍后集成支付网关并适应基于支付的订阅.

Users can be assigned two different roles. The admins can enroll new subscribers and admin users. 管理员用户可以上传第二天值得观看的新图表的图片. 一个详细的解释，为什么它是重要的，目前和突破点的观察也包括在内. A subscriber can filter through all the new charts uploaded based on market, sector, volume, price, etc. This enables them to make more educated decisions on the stock market.
