About Jeremy

Web developer for 12 years, I specialized in analytics engineering and data engineering in the last two years.
On the data side, I build ELT pipelines, model data with dbt, and produce actionable analyses on BigQuery. I have published several open-source projects, including dbt-scribe (automatic dbt documentation generation via LLM) and a custom Airbyte connector for Garmin.
On the web side, I develop and maintain custom WordPress sites — themes, plugins, performance, tracking.
In terms of automation, I design workflows with n8n and integrate AI agents (RAG, multi-agents) to automate business processes.
Do you have a data project, a site to build, or a process to automate? Let's talk!
