I am a data scientist building production AI applications. I write for Python developers who want to get serious about SQL, DuckDB, and local AI tools. My work is published in long-form technical series that build knowledge from the ground up. If you want depth instead of quick answers, you are in the right place.

A lot of the content here follows two threads. The first is SQL for Python developers: a series I started because so many Python devs avoid or underuse SQL. Understanding how SQL thinks changed how I write Python, and I wanted to make that shift accessible to others. The second thread is LLM development — practical posts from building agents, working with local models, and figuring out where AI actually fits in production workflows. I also write about certifications, tools, and the general experience of learning in public.

I’m a husband and dad, which has a way of focusing you on what actually matters. I read mystery, sci-fi, and fantasy when I can stay awake long enough. I’m slowly learning Japanese and enjoy board games when life allows.
