I am an experienced data analyst, living in South Africa. I focus on data analysis work, and am skilled in Python and SQL as well as BI tools like Tableau and Qlik. I've used variety of tools for data cleansing. I have some familiarity with machine learning modelling using Knime and Python, as well as with Big Data concepts and technologies (mainly Apache Spark and Hadoop). I like working remotely, I am familiar with many business concepts and models, and I am a first language English speaker. My background before data analysis was largely in risk management consulting, which helped make me an excellent developer of presentations and reports from empirical data.
