    On-site vendor in a FAANG company - 2 jahre 3 monate

    The goal of the project was to develop a system for automating processes at a Big Tech from US using machine learning techniques. Specifically, the system was designed to help managers to give access to internal applications and optimise the response time for it.

    • Creating a recommendation engine using machine learning models with a rejection option over highly imbalanced datasets. Data visualisation, python programming, data cleaning/processing, feature engineering and selection, model training and evaluation, data analysis and data ETL using python;
    • Performed feature engineering using high imbalanced datasets from various data sources (AWS S3, PostgresQL, MySQL, Cassandra);
    • Handling the full data science cycle, from feature engineering to model deployment;
    • Build a recommendation system to assist upper management with virtual assets access control decision making.
    • Creating, evaluating, deploying and maintaining machine learning models as web services;
    • Implemented techniques to optimize models such as: feature engineering and selection, redundancy detection, outlier detection, over and under sampling, model calibration and dataset drift detection;
    • Designed data pipelines using Python to deal with financial data and migrate date between systems;
    • Communicated results and impacts of the models to stakeholders and relevant parties through reports and dashboards.
