About

This page outlines my path into data systems engineering, with a focus on SQL-backed workflows, APIs, batch jobs, validation, and reproducible data work. Earlier roles in web and mobile development provided the software foundation for working with real-world data, backend contracts, and operational systems.

The role fit I am building toward is practical: maintaining data workflows that other teams can trust, turning files and database records into validated outputs, and keeping the API or batch boundary clear enough for review, scheduling, and handoff.
