Featured Work

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

High-Throughput Core Architecture

Designed and developed the reference proof-of-concept (PoC) for a high-availability Available-To-Purchase (ATP) & reservation engine in Elixir/BEAM utilizing ETS, Broadway, Apache Kafka, and PostgreSQL. Benchmarked to handle 1.2M req/min with sub-millisecond response times, establishing the functional requirements and architectural baseline for the production .NET/CSharp implementation.

  • High-Throughput & Low-Latency Systems (1M+ req/min)
  • Performance focused mindset

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 when there was no documentation for it. 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. Most performance is achieved through careful design and optimization. Best infrastructure 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.
