Hi, I’m Thomas Heisel. I’m a Solutions Engineer and Architect with 15+ years building data and analytics platforms and helping teams turn messy data into reliable pipelines, dashboards, and machine learning solutions.

I’ve worked in customer-facing technical roles across modern data stacks, including Snowflake, Databricks, BigQuery, and AWS, supporting everything from data ingestion and modeling to production ML workflows (MLflow tracking, model registry, batch scoring, and deployment patterns).

My courses focus on practical, scenario-based learning. For certification prep, I create original practice questions that resemble real exam thinking, with clear explanations that teach you how to eliminate distractors and avoid common traps.

If you’re preparing for Databricks certifications, my goal is simple: help you build confidence, find gaps fast, and pass with a deeper understanding that carries over to real projects.
