Björn Hempel

Hello! Hallo! ¡Hola!

Hi, I'm Björn Hempel and I work at ressourcenmangel integral GmbH as Lead Software Developer (Symfony 6.4, Pimcore 11.x), Software Architect and DevOps Engineer. My main tasks include planning, building and ensuring the proper operation of the software created by ressourcenmangel integral GmbH, as well as the required system landscape. I am also responsible for ensuring consistent code quality for the software created using modern software methods such as TDD and CI/CD.

I have extensive experience in the creation, planning and operation of complex software components (service oriented architecture - SOA), as well as the required system landscapes.

In my time before ressourcenmangel, I supervised and developed advertising portals in the publishing industry. This was followed by the development of Rest-API services for business-critical online processes for various customers. Thanks to independently selected and extensive test and deployment strategies, these services are very stable and can be easily maintained and extended by our team. The development and use of modern implementation and quality methods are always a companion in achieving my task goals.

In my private time, I work extensively with localization databases and finding geodata based on WGS 84 coordinates. Finding the nearest places and locations to a given location is the primary goal. PostgreSQL/PostGIS is used for this. The localization tool can be found at the following address: locate.place

Besides my job, I successfully completed my Bachelor's degree in Computational Science (Mathematics, Physics, Computer Science) with a minor in Artificial Intelligence and Machine Learning at the TU-Chemnitz. The thesis, which deals with the classification and recognition of image objects (Image Classification), as well as the training of corresponding image models using Convolutional Neural Network (CNN) and Transfer Learning, can be found here: Investigation of strategies for image classification on small training data sets
