ABOUT ME

Hi, I'm John Serra, a freelance data analist passionate about transforming raw data into actionable insights.

In today's data-driven world, understanding the story your data tells is crucial for success, and that's where I come in.

I've always been drawn to collecting and utilizing data. From collecting data from analog inputs, digital inputs, and simple web apps to capture them. Some of the data went directly to a CRT for visualizations of ongoing processes, while others into devised databases for later scrutiny.
