Björn Hempel

Hello! Hallo! ¡Hola!

Hi, I'm Björn Hempel and I work at ressourcenmangel integral GmbH as a Senior Software Developer (symfony 6.3), Senior 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. Furthermore I am responsible for ensuring a constant code quality for the created software using modern software methods like 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 was responsible for and developed ad portals in the publishing industry. This was followed by the development of usability tools for business-critical online processes for various clients. The development and use of modern implementation and quality methods were always a companion in the achievement of my task goals.

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.
