Featured Work

Real-world impact, architecture, and automation at scale.

Data Engineering & ERP Modernization

Completely re-architected legacy POS and ERP (Comarch & D365) integrations. Led the migration of 100+ fragile SSIS packages into robust, hand-crafted Prefect workflows using Python, Pandas, DuckDB, and Polars.

  • Modular, hand-crafted integration logic
  • High-performance DuckDB & Polars ETLs

Infrastructure & Security Transformation

Architected and deployed a custom Prefect cluster from scratch, implementing unique cloud-function capabilities. Established automated, department-wide security scanning standards that directly drove the core IT transformation process.

  • Custom Prefect cluster infrastructure
  • Department-wide security integration

Engineering Philosophy

I believe that the best infrastructure is invisible. It should empower developers to ship faster, safely, and without friction.

Automation isn't just about saving time; it's about reducing cognitive load and eliminating human error. I strive to build systems that are deeply observable, undeniably resilient, and brutally simple.
