About

I am a data engineer who loves finding patterns and insights in complex data sets. I have over five years of experience in business support and data management teams, where I designed and implemented data pipelines, creating and analyzing reports on RDBMS and block diagrams of unstructured data. Likewise, I have recently completed an online master's degree in data science, which has enhanced my critical thinking and understanding of data environments and machine learning algorithms. My mission is to help businesses leverage data to make informed decisions and optimize their performance to impact society and lead it to a better future.
