Profession

Data Analyst – Data Scientist

Description

I have been solving business problems oriented in data-driven solutions since 1999 and I can handle a large variety of them. I can analyze and transform data and discover patterns to use them as features for different kind of analyses or predictive models.

Service

Ι create updateable, maintainable and reusable Machine Learning and Data Analysis systems in Python using the OOP paradigm. The systems read and preprocess data and can perform automated analyses. The systems may have the ability to train and optimize predictive models and retrain models when updated with new data.

The final user will not need coding skills to use the system’s tools and may access them easily from Jupyter Notebook as well as from other environments or encompass them in their server. Full support to use these tools will be provided.
