Experience

层级项目(德州综合资格重新设计系统)

http://www.yourtexasbenefits.com/Learn/Home

The TIERS project caters to the management and processing of three programs viz; the Texas Public Assistance Program, 帮助低收入者满足食物等基本需求, shelter, and medical assistance; Food and Cash Benefits, which provides financial aid to individuals or groups who cannot support themselves and are funded by taxpayers that enable people to better cope with financial stress during rough periods; and the Medical Assistance Program, which helps lower-income individuals, the elderly, 以及那些需要在公共保险系统中支付医疗费用的残疾人.

这些项目由联邦政府和州政府共同资助，并由各州管理. 最常见的医疗援助项目是医疗补助和医疗保险. 这个集成系统由遗留Java应用程序组成, EJBs, Spring Boot web services, Angular front ends, and mobile apps. 使用的一些工具和技术是REST/RESTful api, Hibernate, Oracle, MySQL, Kotlin, Bash, Docker, Kubernetes, Git, Jira, and Jama.

I was the Java back-end engineer, 利用领域驱动设计构建新的微服务，并为现有的微服务添加新功能, 并为批处理作业的执行创建了Oracle SQL迁移.

GRA Strategic Dashboard

GRA有两个完全独立的运作部门.e.、国内税务署及海关总署. Each of these departments has its internal applications. 高级管理层认为需要一个实时仪表板，根据某些给定的kpi从所有这些应用程序收集和汇总数据.

这涉及到使用Java为每个可操作的数据库构建web服务, Spring, Hibernate, PHP, Laravel, Vue.js, Node.js, MySQL, REST, and RESTful APIs, 利用RabbitMQ作为服务之间的消息传递技术，并使用Azure Kubernetes services (AKS)部署在Azure云上。.

我通过设计GRA战略仪表板简化了高级管理层的战略决策，该仪表板连接并生成来自运营数据库的数据，并使用139个运营和分析kpi分析数据.

Customs Intelligence Application

海关情报系统是一套系统，用以记录检获的违禁品，并追踪毒品及已知贩毒者的流动情况. 该系统主要由海关工作人员在外地使用, especially at border posts, 记录检获物品，并透过推送通知，作为边境哨所之间的资讯交换平台.

该系统是在利用领域驱动设计的同时设计的，并作为微服务实现, with services written using Java, Spring framework, PHP, Laravel, MySQL, MongoDB, Node.. js, RabbitMQ, REST和RESTful api, Docker和Kubernetes.

我为海关风险管理部门创建了一个海关情报应用程序，根据查获的违禁品的类型提供分析，从而改进了情报和执法部门的情报调查和查获案件, concealment methods, and transportation modes.

GRA Competency Assessment System

GRA人力资源工作组很难追踪每个员工的能力水平，以了解他们的工作描述所要求的每一项技能. 提出了一种基于GRA胜任力框架和词典的胜任力评估体系, 西非海关总署在WCO-WACAM(西非海关管理现代化)的支持下编写的文件. 该系统评估每个工作人员与其工作描述相关的能力. For each competency, 对员工进行评估，并给予从1级意识到的熟练程度, Level 2–Application, Level 3–Experience, to Level 4–Expert. 该系统还将在某项技能上具有专家水平能力的员工识别为潜在的培训师，以帮助培训那些缺乏该技能所需能力的员工.

这有助于HR了解每个员工的长处和短处，帮助他们进行能力建设项目. 人力资源工作小组成功地分析了每个员工的能力水平，并在他们的工作描述中列出了所有所需的技能. 它已经开始培训那些需要通过系统认定为培训师的员工来提升技能的人.

GRA Survey Application

GRA人力资源工作组在他们的人力资源意识活动中需要一个定制的调查应用程序，该应用程序将生成关于员工对人力资源角色的意识和理解的综合报告, awareness of HR reforms, access to HR reform documentation, the satisfaction of HR services, 以及人力资源部和行政部的期望.

本系统采用PHP Laravel框架，采用MVC架构模式，MySQL数据库进行设计和开发. 人力资源工作小组成功地进行了调查，并生成了报告，帮助他们确定了活动的方向.

Hospital Management System

我们开发了一个医院综合管理系统
government hospitals in The Gambia. It enables multiple hospitals to have accounts. Some of the modules included are consultation, appointment, lab services, pharmacy, billing, in-patient, and referral. 这是一个采用领域驱动设计的分布式系统，使用PHP Laravel框架构建为微服务, Java Spring framework, Vue.js, and jQuery, 使用RabbitMQ进行服务间通信，MongoDB和MySQL作为数据库. 它能够集中维护病人记录，改善冈比亚公立医院之间病人病史和转诊信息的共享.

Kubejara College Management System

库别哈拉学院管理系统是为满足高校学术和管理需求而构建的多租户系统. 它的功能涵盖了学院的日常管理, including online application, course management module, finances module, academic and transcripts module, HR module, asset management module, and payroll module.

该分布式系统采用领域驱动设计，并以微服务的形式实现. 用于构建服务的主要语言是Java, Spring Framework, PHP, Laravel, MySQL, Node.js for the back end, and Vue.js for the front end. 该产品目前被冈比亚的许多学院和大学使用.
