Back to original languageAbout Andreas
With over a decade as an independent entrepreneur, I have deepened my expertise.
With over 35 years of experience with CNC controls (SINUMERIK), my focus is on the development and optimization of machine software for machine tools, where I successfully apply my knowledge of SIMATIC Step 7, TIA Portal, and drive technologies.
In parallel, I have further expanded my skills in Java development, particularly in connecting production control systems with inventory management and ERP systems. Through customized software solutions and the integration of SQL and NoSQL databases, I contribute to increasing efficiency and process optimization for our clients.
