About Alfredo

Developer at heart, I love working with data and have been doing so for almost 5 years, both in personal projects and working for companies in the Streaming, Banking, Textile, and Insurance sectors.

Whether it's developing a web application, an automation, an application that collects data from any source, processes and transforms it, and uploads it again or ingests it, or one that processes the data and displays it, or converts it into a DataFrame and ingests it into Azure, or it's the visualization of this same post-processed data for decision-making, migrations... Whatever the challenge, I'm eager to face it.

While I have done all of the above in my years of experience, there are two areas I enjoy more than others, and those are web development (including its database part) and data ingestion, loading, and visualization.
