About

My childhood dream was to be a Power Ranger, but unfortunately that wasn't achievable, so instead I became a mechanical engineer and, later, a data analyst. I worked for four years as a product engineer in a refrigeration company, where I learnt that I liked better working with data after spending some time automating stuff with VBA and Python. After a few courses on data science and data analysis, I decided to pivot my career, and now it's been over a year that I've been spending my days with my friends SQL, Tableau and Python, mostly working with financial data and building dashboards. I'm a levelheaded and analytical person, and I'm always open to learn something new.
