What I'm looking for

Seeking a challenging role in data analysis where I can leverage my technical skills and experience to drive data-driven decision-making and contribute to innovative solutions.

I am a dedicated Data Analyst with over five years of experience in transforming raw data into actionable insights. Currently, I work as a Freelance Web Developer & Solutions Architect, where I have designed and deployed a full-stack platform using Python and PostgreSQL, and developed a RAG-based chatbot using LangChain and OpenAI.

Previously, I worked at Mapegy GmbH, where I collaborated with cross-functional teams to enhance data quality and conducted comprehensive analyses to identify significant trends. I also served as an Account Manager at Midland Credit Management, developing performance metrics and interactive dashboards using Power BI.

I hold an MSc in Computer Science with a focus on Big Data and Artificial Intelligence from SRH Berlin University of Applied Sciences. My technical skills include advanced BI development, SQL, ETL, and programming in Python. I am passionate about leveraging data to drive informed decision-making and am committed to continuous learning in the field of data science.
