I did my bachelor's in Punjab, India and worked as a decision consultant for three years after at MuSigma. After that, I decided to study Data and Knowledge Engineering at the Otto-Von-Guericke University (OVGU) Magdeburg, where I finished my degree in 2022. I did a lot of research as a HiWi on Natural Language Processing and Time Series Prediction. In addition, I worked as a Machine Learning, Data Mining and Deep Learning tutor for several terms. Currently, I am pursuing my PhD at the DZHW in cooperation with the OVGU.
