Experience
- Guidants Android (Development)https://play.google.com/store/apps/details?id=de.boersego.gmt.android
Guidants gives you real-time financial market data, analyses, and access to a community of pro traders. I created this app and its predecessors and have worked on it for many years.
A technical highlight is the use of real-time stock data and the powerful stock chart analysis package that the client also uses on the web. It is driven by ejecta-v8, my project that embeds Google's v8 JavaScript engine into Android apps similar to how Node.js works. - Ejecta-v8 Library (Development)https://github.com/godmodelabs/ejecta-v8
To reuse the existing code that was written in JavaScript, a client commissioned me to write a library similar to Ejecta.js for Android.
With the help of colleagues, I wrapped Google's v8, added Canvas, AJAX, and WebSocket APIs, and created a layer for the easy wrapping of both C++ and Java/Kotlin functions to be used by JavaScript. - Om7Sense Energy Management (Development)
I co-founded Om7Sense, a startup focusing on energy management. Using IoT technologies and an intuitive front-end written in React, energy usage can be easily quantified. The back-end was developed in high-availability Java EE using Eclipse Kura and communicates via the MQTT protocol standard.
