Hi, I'm Bernardo 👋

I work in Data & Analytics, with a strong focus on turning messy, real-world data into information people can actually trust.

My background combines analytical skills with a solid understanding of business processes, which means I care not only about what the data says, but whether it is reliable enough to support decisions, analytics or AI.

I believe data is more than numbers —
it’s a system of definitions, assumptions and trade-offs that must be made explicit.

🔎 What I focus on

  • Data quality as a foundational layer, not a cleanup task
  • Working with imperfect, inconsistent and evolving data sources
  • Bridging business logic with technical implementation
  • Making data limitations visible instead of hiding them downstream

I’m less interested in hype and more in: clarity, consistency and trust in data.

📌 Featured Projects

  • Data Quality Hell
    A real-world data quality project focused on common production problems: inconsistent schemas, ambiguous roles, missing values and unclear definitions.

    The goal is not to create a “perfect” dataset, but to build reliable foundations before analytics or AI.

  • Data Science Salary Analysis
    An analysis of data science salary trends across sources and regions, focused on extracting insights that are actually useful.

If you care about building data systems that hold up in practice, we’re probably aligned.
