Back to original languageAbout Oliver
I am a frontend developer with a focus on Angular, as well as experience in product data management and e-commerce systems. Through my combination of technical development and data-oriented work, I bridge frontend development with structured, practical business solutions.
I completed my technical training at Developer Akademie (TÜV-certified training provider) with a focus on modern web development, JavaScript, and Angular, as well as agile working methods. In my previous role as a Junior Software Developer, I accompanied complex web applications from conception to implementation.
My project experience includes, among others:
- Development of an internal survey web application (including dynamic questionnaires, evaluation with charts, and MS Teams integration for reminders)
- Development of a web application for deployment and resource planning as an alternative to Outlook Calendar (including Google Maps API for travel time calculation)
- Development of an automated time and deployment documentation
In the area of product data management, I structured and optimized product data for a large online shop (Casando) at Holz Richter GmbH and created XML imports for prices and articles. This gives me a good understanding of e-commerce data structures, shop systems, and data quality.
Additionally, I have experience in IT administration, customer support, and technical product consulting in the field of fittings technology.
I am currently expanding my skillset in Flutter to develop my own mobile applications and, in the long term, to publish my own digital products.
