Experience

Animal Adoption Application

这家动物收容所提供一项计划，允许人们赞助动物(每月支付固定金额)。. In return, they receive regular updates via mail or email. Since this process is very obscure, 我开发了一个应用程序，用户可以选择他们的动物，并通过应用程序直接赞助它们. The app lets the sponsor view updates and news about their chosen animal.

The app was written as a PWA with Vue and AWS Amplify.

EventManager

I developed this web application for a customer who regularly hosts events. He can organize guests and events and send out invitations through the app. Guests can use the app to either accept or decline invitations.

Warehouse Management System

I developed a warehouse management system for pharmacies with a colleague. 该系统的目的是让药店对他们即将用完的药物和成分有一个概述，这样他们就可以一键订购.

We have used Laravel with MySQL in the back end and j|Query in the front end. The application was hosted with DigitalOcean.

GIS Analysis Software

http://smartmap.at/

I developed a production site analysis software for doctors. After choosing a location, 医生可以看到有多少人住在附近以及他们的其他细节. The front end is built with Vue.js, and the back end with Node.js is hosted on an EC2 instance. For the database, I used RDS with PostgreSQL.

Questionnaire Management System

一个应用程序，用户可以在其中创建和管理不同的问卷. Through the management system, they can see results and various key figures. I was managing a team that was designing and building the application. My responsibilities ranged from planning to developing the application.

Children Sponsorship

一家非政府组织需要一份申请，以便将捐赠者与需要帮助的儿童联系起来. Through this application, people are able to sponsor children. Upon sponsorship, 他们可以看到这些孩子的各种更新，并能够与他们交流.

I managed a small team that was responsible for building the application. My responsibilities ranged from managing the team, planning, communicating with the customer, and developing parts of the platform.
