Christopher Landaverde

Marketing Engineer

I'm a Marketing Engineer who builds systems at the intersection of data engineering and growth strategy. After being laid off in December 2024, I've been contracting and contributing to open source. I'm passionate about MMM, AI Agents, and privacy-first server-side tracking.

Currently open to contract work or full-time opportunities.
