About Me
From my early childhood, I was keen to acquire new skills. At age 13, I began to learn different programming languages. At age 15 while still in high school, I took university courses in business administration and computer science. After receiving degrees in mathematics and business administration, I did a Ph.D. in operations management at the University of Mannheim. During this period, I conducted research on optimizing production and service systems under stochastic and time-dependent effects and presented my work at many renowned international conferences. In 2019, I successfully finishing my Ph.D. thesis.
In 2020, I founded Heidelberg Analytics to provide freelance services. I am developing intelligent applications in the areas of mathematical programming and software development. I combine my technical expertise in cutting-edge technologies with a sound knowledge of business.
