Experience

  • Animal Adoption Application

    This animal shelter offers a program that gives people the option to sponsor animals (paying a fixed amount per month), and in return, they receive regular updates via mail or email. Since this process is very obscure, I developed an app where users can choose their animal and sponsor them directly through the app. The app allows the sponsor to view updates and news about their chosen animal.

    The app was written as a PWA with Vue.js and AWS Amplify. As per customer need, I am currently rebuilding it with React Native.

  • 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. The system's aim was for pharmacies to have an overview of what kind of medications and ingredients (for pharmaceuticals) they are running out of so that they can order them with one click.

    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
    https://smartmap.at/

    I developed a production site analysis software for doctors. After choosing a location, a doctor can see how many people live in the vicinity and other details about them. 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

    An application where users are able to create and manage different questionnaires. 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

    An NGO required an application where they can connect donors with children in need. Through this application, people are able to sponsor children. Upon sponsorship, they can see various updates from these children and they are able to communicate with them.

    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.
