About

I'm Alexandra Hernandez, the Interim Data Operations Manager at McNulty CPA. With a B.S. in Machine Learning and Computer Science from UC San Diego, I specialize in building scalable data systems, ML pipelines, and intelligent automation that bridge technology with real-world impact.

My journey in tech started early–creating Minecraft mods and command block games in elementary school, which sparked a lifelong passion for programming. In high school, I earned my International Baccalaureate Diploma with a focus on Computer Science and Biometrics, and built my first game and mobile app using JavaScript and Java.

Since then, I've worked across research and industry, from developing text-to-SQL systems with Cortex Analyst at InSite Health to building data visualization tools for Chen Battery Lab and creating unsupervised ML models for accent classification. Whether I'm migrating databases, automating data pipelines, or integrating LLMs, I'm driven by making advanced technology accessible and actionable.
