Experience

ItoI - Inspection to Invoice

一个将汽车归还过程数字化和自动化的web应用程序. 在每次租赁合同结束时, 汽车将被归还给授权的LeasePlan经销商, 哪家公司会对车辆的状况进行广泛的视觉和技术检查. 结果记录在检查表中，并拍照. 超出正常磨损的损坏将向客户开发票.

Inspection-to-Invoice应用程序取代了手工填写纸质清单的繁琐过程, scanning it, 把它送到发票部门，由他们来打印, manually inputting values, 用现代时尚的解决方案给顾客开发票, 只需点击几下就可以完成工作.

作为这个项目的首席开发人员, 我设计了应用程序架构, developed the back end, 与设计UI的前端开发人员密切合作, 并与世界各地的许多团队合作，帮助他们在当地连接和实施新流程.

皮卡比——描绘一个更健康的世界

准确的食物摄入信息在很多方面都很重要, 比如个人健康和健身, academic research, monitoring regulations, and commercial usage. 然而，收集可靠的数据是如此困难! 我们仍然依靠手工日记或调查，这既繁琐又耗时.
Piccabi是一个突破性的人工智能模型，可以识别食物并提供准确的分量估计. 一切都用一张简单的照片，用手机拍的.

As a founding member, 我是这个令人兴奋的大熔炉的一部分, 在任何可能的地方提供帮助，并陷入技术和非技术任务中. During this time, 我学会了与不同层次的利益相关者打交道，并很快适应了在那些“拆散你”的人面前展示和捍卫自己想法的挑战."
由于我们从未设法获得足够的资金或支持，这个项目处于搁置状态, 但这仍然是一次不可思议的冒险和经历.

Workload Automation - Control-M

社会保障部的核心流程之一是夜间付款批处理作业套件, 负责处理它们支持的每一个模式和允许.
作为全球现代化进程的一部分, 我的任务之一是自动化他们的遗留解决方案, based on an old .NET WinForms应用程序，操作人员仍然手动输入参数, values, 并单击按钮启动工作，并在完成时查看其状态.
在将核心作业功能从WinForms中提取到一组核心库之后, 我已经能够将它们打包成一个命令行工具(一个控制台应用程序)，这样它们就可以通过DOS命令或PowerShell执行. 这使得该部门不得不出去招标通用调度工具，并选择Control-M(基于Java的)作为首选.
与操作员团队密切合作, we automated the scheduling, execution, monitoring, incident creation, 报告流程要求夜班人员从8人减少到2人, 一个积极工作，一个随时待命.
