About Sara

I build AI systems that turn messy, manual work into something that runs itself.

Over 5+ years I've taken products from idea to scale — used by 400,000+ people — and I now focus on the automation layer underneath: AI agents, RAG-powered search, sentiment analysis, and end-to-end data pipelines. I'm part of the core AI team at Consensys/MetaMask, where I recently automated our department's data pipelines and built an MCP that lets anyone query the data in plain language, with AI-generated insights on top.

If your team is losing hours every week to repetitive tasks, I find what's worth automating, build it, test it on your real data, and hand it over working. The goal isn't just efficiency — it's giving your people their time back for the work only humans can do.
