Bridging technical execution with organizational strategy

Hi, I'm Marcello De Filippis, a Software Developer and Data Analyst based in Hamilton, Ontario. My path to tech wasn't exactly linear. I actually started in Human Rights and HR, which taught me a lot about how people and organizations tick. Eventually, I realized I wanted to build the tools that help those organizations run better, so I went back to school for Data Science and Software Development. Today, I live at the intersection of those two worlds. Whether I’m building a CRM with React, automating messy data pipelines in BigQuery, or using SQL to find hidden revenue gaps, my goal is always the same: making sure the technology actually serves the people using it. I’ve had the chance to do this for big names like Geotab and Loblaw, as well as in the public sector. I’m at my best when I’m solving a puzzle—whether that’s a bug in the code or a bottleneck in a business process."
