Software

My software development experience is primarily in the field of data science, with most of my work involving the development of data automations, including data pipelines and complex visualization tools using Python (pandas, PySpark, matplotlib, bokeh, python-pptx etc.) and PowerBI (incl. DAX and PowerQuery's M).

I have also acquired a diverse set of skills from personal projects, ranging from cloud architecture in Azure and AWS to web development with Nuxt.js.

Data Engineering for Social Research

I have extensive software development experience in building data infrastructures for large multinational sociological surveys, including data cleaning, modelling, and visualization. This development was closely integrated with understanding and automating business processes, which has given me a unique perspective on how to leverage technology to improve efficiency and effectiveness in various domains. The projects also included extensive cross-team and stakeholder communication, which has honed my ability to translate complex technical concepts into actionable insights for non-technical stakeholders.
