Rafael in a few words
Hey there!

I have a proven track record of delivering outstanding results in data analysis and I have mastered the art of machine learning and deep learning modelling.

My education, which includes a distinguished MPhil in Health Data Science from the University of Cambridge, a 90.5% distinction overall degree mark in my MSc in Artificial Intelligence from the University of St Andrews, and a first-class BSc in Computer Science from Newcastle University, has given me a strong foundation in multiple programming languages such as Python, SQL, R, Java, Matlab, Javascript, and HTML/CSS. Through the development of numerous side projects, freelance jobs, and research, I have also honed my skills in cutting-edge technologies and frameworks such as Scikit-learn, Tensorflow, Pandas, Numpy, Matplotlib & Seaborn, Node.js, Firebase, and Flask which I will use to elevate your project to the next level.

To be more precise, I can help you in:

- Data preprocessing and cleaning
- Supervised/ Unsupervised learning
- ML and DL model development
- Model optimisation
- Regression analysis
- Hypothesis verification
- Clustering
- Time series analysis
- Image processing
- Developing a web platform where users can interact with the model / present your findings
- Full-stack web platform
- Web Scraping

With a proactive personality and a love for learning, I am always eager to take on new challenges and excel in any situation. I always bring my best to the table and I am beyond excited about the opportunity to collaborate with you!
