Since August 2019
In August 2019 I took the opportunity that Open-Xchange provided me to continue working with Apple technologies on native iOS apps exclusively. The transition realised a long term career goal which I prepared for in my free time since a few years. My self-taught skills enabled me to hit the ground running. OX Mail is the product I am mainly working on with Xcode and Swift involving the VIP architecture, delivering it via GitLab continuous integration and Visual Studio App Center (previously Hockey).
From July 2018 to August 2019
Focus on front-end and mobile technologies. Developing fully localizable single page applications with Vue.js, Vuex, Backbone, TypeScript and LESS. Testing with Chai, Sinon.js, Selenium and Mocha. Native iOS app development using Xcode, Swift and delivery via GitLab continuous integration and Hockey. Node.js middleware and build chain development with Express.js, webpack and Grunt.
PHP Backend Developer
From January 2018 to July 2018
I worked on the enterprise grade backend for millions of Android client apps which is built on the Symfony framework and run on Amazon Web Services. Migrating event logging from MySQL databases to Elasticsearch and extending custom statistical analysis tools were two major missions.
DeineTierwelt GmbH & Co. KG
From September 2016 to December 2017
From April 2016 to August 2016
Developing and implementing websites and web applications for small and medium sized customers based on common frameworks and content management systems. Creating Virtual Reality demos for an enterprise customer at the International Automobile Exhibition 2016 using Unity3D and the Oculus Rift.
From May 2015 to April 2016
Developing and implementing enterprise websites with TYPO3 and developing extensions for it. As part of a multidisciplinary Scrum team focussing on research and development I developed a preference for agile project management. We sticked tightly to the theory of Jeff Sutherland. I was involved from setting up a continuous integration and deployment process to implementing responsive front-ends from scratch. Important projects I contributed to were the relaunches of TÜV NORD GROUP, EKD and Sonepar Germany websites.
Web and Application Developer
DER Fuchs GmbH
From January 2015 to May 2015
I joined a team of young developers to maintain and evolve a web-based in-house solution for all business processes and the xt:Commerce online shop. Complementry projects also include the development of mobile applications for Windows CE with C# and the .NET compact framework. In 2014 I took the lead as a maintainer and worked in collaboration with the external contractor initOS on the corporate migration to Odoo.
Apprenticeship as an Information Technology Specialist
DER Fuchs GmbH
From 2012 to 2015
Original qualification title as officially recognized in Germany: "Fachinformatiker Fachrichtung Anwendungsentwicklung". This apprenticeship normally takes 3 years. My good grades and previous graduationen allowed me to graduate one year earlier but I chose to graduate half a year earlier to still participate in half a year of interesting subjects.
This vocational education is a lot more practically oriented than the Technical Assistant For Information Technology. During the first year 60% of the time are practical work at the company office. The remaining 40% are occupied by theoretical studies in the vocational school. Beginning with the second year the distribution shifts to 80% and 20%.
From 2010 to 2012
Order processing, on-site support for information technology and improving used software solutions like Microsofts Dynamics NAV. While taking care of the corporate design in the German subsidiary I also designed a full page advertisement for DSHwood which was published multiple times across the country in respective forestry magazines.
Internship .NET Development
From 2009 to 2010
With this internship, after becoming a technical assistant for information technology, I gained the final requirement to be eligible to study at a college. However the frontline, where real life and work takes place, always interested me more than studying theory for years. I worked on Microsoft Office Add-Ins an Windows Presentation Foundation based features in the flagship product HM-LIMS which is a laboratory information management system used by major quality assurance laboratories in Germany.
Technical Assistant For Information Technology
From 2007 to 2009
Original qualification title as officially recognized in Germany: "technischer Assistent für Informatik". This education includes (among other subjects) theories in information technology, studies of hardware and electronics, software development and administrative tasks. It cover a lot from in-depth studies of relational databases over setting up distributed Active Directories to practically designing and soldering circuit boards.
Kaiserin-Auguste-Viktoria Gymnasium Celle
From 2003 to May 2007
Because I developed a vital interest in information technology early, I took a shortcut to becoming a technical assistant for information technology after 10th class.
