Experience

Insurance Shopping Questionnaire Engine

While working for Embroker, 我领导了创建保险问卷的通用解决方案的实现. 我们创建了一个引擎，用于生成具有适用规则和验证的保险购物问卷表单. This extremely improved and sped up the business response to market needs, reduced the needed development time, and greatly reduced the number of bugs in that part of the application.

它发现即将推出的硬币库存，并在该硬币库存的名称发送给这些集团之前购买它们，因此价格仍然相对较低. The bot then sells the coin stock at a price before the dumping occurs. 该机器人仅用于泵和转储交易，不能用于其他目的.

Technologies used: Python.
