As a Machine Learning Engineer offering services as an independent, my primary responsibility is to develop machine learning models that solve complex business problems. I work closely with my clients to understand their data and the problems they are trying to solve. I analyze and preprocess data to prepare it for training machine learning models. I build and train machine learning models using popular frameworks like TensorFlow, PyTorch, and scikit-learn. I evaluate and select the best machine learning model based on the requirements of the client, and deploy the model to production environments using APIs, containers, or other deployment techniques. I provide documentation that describes the machine learning model, the data used, and the evaluation metrics. I provide unit tests to ensure that the machine learning model is working as expected, and ongoing maintenance and support to ensure that the model continues to work as expected.
