I build the data infrastructure that turns messy data into business decisions.

Most bad decisions start as good data that nobody cleaned.

Extract, load, transform. Business intelligence built on the modern data stack.

  1. Extract

    Pulling data from wherever it lives — APIs, databases, flat files. Python when there’s no managed connector, which is more often than vendors admit.

  2. Land

    Raw responses to object storage before anything touches the warehouse. Replayable, and a broken source doesn’t corrupt what’s downstream.

  3. Load

    Batch ingestion into Snowflake. Raw stays raw — no renaming, no casting, no flattening at the door.

  4. Model

    dbt from staging through marts. Version-controlled, tested, and reviewable. Every transformation lives in one place.

  5. Visualize

    Streamlit, Power BI, or a custom front end. The number is worthless until someone can act on it.

About

My name is Dieurode Tassy. I've spent the better part of my career on the technology sales side of things, most of it working with business leaders to understand what they actually need and advising them on the right path forward. Lately I've been making the shift from selling software to building it myself.

My projects run on the modern data stack: SQL, Python, S3, Snowflake, dbt, Dagster. Cloud infrastructure and AI, pointed at the kinds of questions businesses cannot get out of a spreadsheet. My main build digs into two million SBA loan records and surfaced a 6.5x default-rate gap between loan vintages: 2007 originations defaulted at 31.7%, 2012 at 4.9%. Exactly the kind of thing I got into this for.

I've found my home on the analytics side, helping business leaders actually understand their data. What I care about has not really changed. My passion for helping businesses grow with technology is the same. I am just building it now instead of pitching it.
