  • Apr 2019 - Aug 2019

  Designed, planned and developed the iOS application pretixSCAN ( https://github.com/pretix/pretixscan-ios ). Took special care to create a usable, stable application that can be used in both online and offline mode, with changes being synced whenever a connection was established to the server backend. The app was developed with Open Sourcing in mind, so code quality, readability and documentation were especially important, as were compatibility with new and old phones and OS versions. The project uses Swift 5.1, swiftlint, and CocoaPods. Special care was taken to have as little dependencies as possible. Show less

  • Jul 2017 - Dec 2017

  Fineway is a startup that aims to use a Machine Learning Chatbot to build the perfect vacation for its users, from hotel reservations to flights to trips. I worked on the chat fragments team, improving the conversational ability of the bot to keep facts in mind longer than just one question-answer-pair. Then I switched to leading the overhaul and redesign of the Data Pipeline or ETL Service, with better architecture, improved distributed performance, and the ability to infer data points from given data. Technologies for this included Python with Django, but also data science tools like Pandas and Jupyter Notebooks, as well as ElasticSearch, Docker, and various continuous integration services.

• Senior Software Engineer

  • May 2015 - Jun 2017

  I worked on implementing many new user interfaces for the Elgato Eve app that can be used to control and update the various Elgato IoT devices. Additionally, I lead a complete rethinking of how Elgato manages its code, breaking up a 15 year old mono repo of tens of gigabytes into separate projects and dependencies, and holding workshops to introduce Git and Git Flow into the company’s workflows. Programming languages for these projects were Swift 3 and Objective-C, using Apple HomeKit, AppKit, WatchKit, as well as manual management of Bluetooth and network connections to IoT devices. A separate project was a real time syncing service for the company’s gaming division, which concerns itself with live streaming of gaming videos. This service enables the instantaneous synchronization of over half a million devices’ settings with delays of less than 100ms. It is written in Python, Django Channels, and Twisted, using (web) socket connections. Show less

  Starting as employee #1, I’ve hired employees, lead teams, created server landscapes, designed software architecture and initiated, planned and worked on several large scale mobile and cloud projects. Anfema was about 40 developers strong when I left. Creating and propagating processes like Scrum and Continuous Integration was very important in this position, as was a commitment to quality, high performance software, and human leadership. We created a culture of highly reusable libraries that, combined with the CI pipeline, allowed us to output a very high number of apps per month. Technologies included Python, Django, Twisted and Docker for the server side, as well as Objective-C and Swift 2 for mobile apps, using among other things MapKit, Location Services, WebKit, PSPDFKit, OpenGL ES, and Unity.
