Work Experience
Data Analyst
Farfetch
- Performed in-depth analysis of discount discrepancies experienced by customers. This investigation allowed not only for a more consistent customer journey but also revealed issues with the way final prices were calculated.
- Developed a monitoring dashboard for the Logistics team to help give visibility to the order allocation behavior among partners. These visualizations also helped our partners to gather a better sense of how they were performing and where to improve.
- Developed an impact assessment of a newly developed packaging algorithm. This analysis supported the stakeholders on the decision to focus more efforts on certain types of recommendations while identifying the algorithm was not ideal for others.
Senior Data Analyst
Banqi
- Developed and improved the main company report used to track the most relevant metrics related to the achievement of the company's strategic goals.
- Developed automation for the main company report using Python and Airflow, reducing the required time for updates and allowing other members to take over maintenance.
- Took more of a leadership role in the team, supporting the other members on how to produce more meaningful and insightful analyses and communicate those findings in a clear and engaging way.
- Analyzed the company's main trends, showing how performance changed over different products and user cohorts. This helped shift focus to specific cohorts, allowing for improvements in user activation and retention rates by up to 25%.
Data Analyst
Banqi

Experience
Investigation and Predictive Analysis of COVID-19 Patients Admitted in ICU
https://www.kaggle.com/code/epdrumond/icu-admission-data-cleaning-and-exploration/notebookIn the second part, several machine learning algorithms were applied to predict users' future conditions with two distinct approaches. The first one considered only the measurements taken right after the patient was admitted to the hospital and tried to predict the likelihood of UCI treatment being necessary. In the second approach, the same prediction was made using data from the two most recent measurements, taking advantage of the change over time to produce more accurate predictions.
