Junior Data Analyst | From Toronto, Canada | Based in Madrid
Welcome to my GitHub! I'm a motivated Junior Data Analyst, excited to bring together my technical abilities and diverse experiences to solve real-world problems with data.
After earning my Bachelor of Commerce in Information Technology Management at Toronto Metropolitan University, I embarked on a unique journey—traveling, teaching English in Japan and Thailand, and honing my leadership skills as a chef and baker. Along the way, I developed a strong foundation in adaptability, communication, and teamwork.
During a career break, I rediscovered my interest for technology and data, leading me to complete a 9-week intensive (+400hrs) Data Analytics Bootcamp at Ironhack. Through hands-on projects, I gained experience solving real-world problems by analyzing complex datasets, building predictive models, creating dynamic dashboards, and uncovering actionable insights to drive decision-making.
Here are a few projects that showcase my skills:
-
Bakery Sales Analysis
Analyzed sales data of a bakery to enhance revenue and efficiency. Delivered actionable insights using BI techniques, KPIs, and dashboards. -
Vanguard A/B Testing
Evaluated the impact of UI changes on user experience and completion rates. Conducted EDA, calculated KPI's, hypothesis testing, and created dashboards to visualize key findings.
I'm actively seeking a remote data analytics role where I can apply my technical skills and global perspective to drive impactful solutions. If you’d like to collaborate or discuss opportunities, feel free to reach out:

I trained for and completed my first marathon (42.2 km in 3:54) within a year of starting running and while caring for my young son—proof that I thrive under pressure and love tackling challenges!
