Theo in a few words

I'm a professional freelance Software Developer originally from Sydney, living and freelancing in Berlin for the last 5 years. I've worked for a range of European and international clients during my professional career, always striving to produce high-quality, testable, and maintainable software.

I have several years professional experience working at times as either a native mobile developer or full stack web developer. I've worked extensively with React, React Native, Redux, GraphQL, REST, Python, Flask, Django, PostgreSQL, Redis, Swift, Typescript, SwiftUI and UIKit.

Mobile application for configuring and monitoring connected devices in the IoT space.
The Datacake mobile application was developed for Datacake GmbH to aid existing and new customers in settings up, configuring, and monitoring their hardware devices connected to the Datacake cloud. The application coexists as a complement to the powerful configuration suite offered by the Datacake web application while leveraging mobile-specific features such as hardware configuration over ad-hoc WLAN networking and customizable push notifications.

React Native was used in order to leverage code sharing between the existing React-based web application. All UI components are platform-independent while a shared networking library was developed for use on the web and mobile frontends. Real-time communication with the Datacake API is done over the MQTT protocol.
