Hi there, I'm Luis 👋

I'm an mechanical engineer transitioning to the data science industry. I'm passionate about leveraging data to create valuable insights and solve real-world problems for businesses.

Projects

Here are some of the projects I'm currently working on:

  • Forecasting Food Retailer: developed a multi-step forecasting LightGBM model to predict sales of 10 food products in 2 different stores using recursive forecasting with a mean average error of 5 daily selling units.

  • End-to-End Machine Learning App: created a weather forecasting app using my own Raspberry Pi and a microcontroller to predict the room temperature at home with an error of 5% using XGBoost.

  • British Airways experience: identified top 5 reasons for customer dissatisfaction using NLP from actual reviews and built a classification tree-based ML model that helped identify the 5 most important factors when booking a flight.

  • Retail market analysis: analysed Madrid neighborhoods using Airbnb data, identified 11 key areas for maximising renting revenue.

  • Solar power plant generation analysis: developed root cause analysis for equipment failures, resulting in the implementation of preventive measures that reduced future failures by 30%.

Skills

  • Python: Pandas, NumPy, Scikit-learn, Matplotlib, Seaborn
  • Data Visualization: Tableau
  • Machine Learning: Regression, Classification, Forecasting
  • Deep Learning: Neural Networks, Tensorflow, Pytorch
  • Database Management: SQL
  • Statistical analysis: Design of Experiments, Statistical Hypothesis Testing
