About

About me

Hi, I'm Juliana — a data-driven technologist based in the Bay Area, originally from Colombia.

I started my career in international business and finance, then transitioned into tech through an apprenticeship program at Intuit, where I was promoted from Software Engineer I to II within 18 months. That path gave me a unique combination: I understand both the business side of data and the technical side of building the systems that manage it.

My work spans frontend engineering at scale (QuickBooks Payments, millions of daily transactions), CRM implementation and data workflow design, and financial data management across multiple industries. I'm fluent in English and Spanish, which helps me communicate complex technical concepts to diverse teams.

I'm passionate about applying these skills where they make a real difference — in organizations that use data not just for profit, but for people.
