I am an experienced Machine Learning Engineer, skillful in Python, Big Data, Deep Learning and Earth Observation. As a researcher, I am very familiar with the state-of-the-art and can provide in-depth analyses. I have completed several projects including time-series forecasting, anomaly detection, computer vision, remote sensing & satellite data analysis. I have implemented and deployed several Machine Learning models that are currently used in production: - An NLP model that identifies cardiology-related scientific abstracts and categorizes them into more specific categories. - A wildfire forecasting model that uses weather and satellite data. - An anomaly detection model that produces risk scores for vulnerable servers. I am excited to solve diverse problems as a freelance Data Scientist and waiting to tackle the next challenge.

I have great experience in web scraping and ETL, mainly using Python and the panda's library. I am familiar with proxies and many scraping techniques. Also, running them on the cloud is my forte, as I am familiar with many cloud services. Finally, I also have experience in Big Data and machine learning using Apache Spark (both Scala and Python). I have acquired that from my job as a freelancer, in which I applied machine learning algorithms to economic data (cryptocurrency).
