I build data systems that survive contact with production.

I'm Evan Volgas, Senior Staff Data Engineer at Nitrogen Wealth, where I build AI-enabled data infrastructure for wealth management. Previously Netflix, Mailchimp, Capital One, and a handful of startups. 20+ years building data and distributed systems.

I have seen startups and data teams fail. I have seen them succeed. The pattern is consistent: pilots that never reach production, architecture decisions that haunt you, healthy metrics on broken systems. The technology usually works. The problem is everything else.

I write about what I've learned. I also maintain a handful of misfit data tools.

If you want to talk about data contracts, agent evals, orchestration, or memory, get in touch.
