Innovative web and app solutions

I have been developing professional, scalable and performant web and mobile applications with React and React-Native for over 6 years.

Here you can find a small excerpt of my previous and active projects.

React web app for the administration of pool operations

I worked on a web application for a medium-sized client. The focus of the React app was to digitally map the business processes in swimming pool operations. This includes monitoring water quality, managing water cycles within the pool, but also various evaluation options for quality assurance.

React-native app for heat pumps with battery storage

I developed a React-native app for a medium-sized client. The app was intended for use by end users. The app allows the owners of the heat pump to view the current household consumption. But functions such as solar energy balance, grid feed-in and various evaluation options are also among the key features of this app.

React-native app for duty scheduling in the emergency services

DienstBuddy is a mobile app for easy shift planning and shift swapping for individuals in the emergency services. It is planned to offer the features for firefighters 🚒 or healthcare workers 🏥 in the future. However, the first version focuses on colleagues in the emergency services 🚑 The app stores data locally and offers an intuitive way to manage and swap shifts. You can also share your own duty rosters with colleagues.

Primary Tech-Stack: React-Native, Supabase
Implementation period: Currently still being implemented

React weather app

Using the OpenWeather API, I built a small React app that displays the current weather and the forecast for the next five days.

The search includes an autocomplete function, and the last search queries are saved and displayed as suggestions below the input field.
