Data Analyst & AI Systems Builder
I turn messy, real-world data into decisions people can act on.
I'm Neyda Larson. I build validated dashboards and data models from raw, real-world data, plus the Claude agents and automations that speed the work up. Below are real builds that fix real problems. Open to remote data and AI roles.
