🛠️ About Me
Hello, I’m Steven — also known as stevefox-linux.
I'm a full-stack system developer with 5+ years of hands-on experience in building, deploying, and automating business-critical applications.
From warehouse barcode integrations to report generation systems powered by FastAPI, JasperStarter, Linux automation, and DevOps pipelines, I design solutions that work hard in the background — so people don’t have to.
