I started with Milan in Championship Manager 03/04, went through an almost perfect auction and a season shaped by injuries, then built Fantabuddy on holiday: a system that turns player lists, history and APIs into an auditable auction report.
Python-native ingestion with dlt (dlthub), SQL transformation with dbt, and a single Unity Catalog schema as the contract between them. Notes from wiring them together on a real Databricks workspace — including the naming collision that bit me in actual code.
A design story of dataprof: why I built a profiler around Apache Arrow, how it changed the architecture, and how this journey led to contributions to arrow-rs’ Parquet reader.
A technical exploration of async/await in Python and Rust: how the same syntax hides completely different execution models, with practical examples from contributions to Tokio and Python projects.
A deep dive into Mosaico, the robotics data platform written in Rust: client-server architecture, semantic ontologies, data-oriented debugging, my journey within it, and the integration with Data Contract Engine.
