RESUME.md

Jonathan Gallardo-Kerth

Extroverted Full‑stack software engineer. I build accessible, high‑performance web apps and scalable serverless data flows that process millions of rows. Seeking frontend or full‑stack roles where I can apply and expand my expertise in UI, data pipelines (ETL), and cloud‑based application development.
