I have experience in applying Machine Learning on a variety of domains. Some include bank transactions, text, timeseries, network traffic and many more data. I spent a substancial amount of my free time to perfectionize my skills in the areas of model explainability, efficient ML pipeline construction, data cleansing and software engineering.
