At AutoZone, I modernize and migrate enterprise applications to GCP while improving reliability, security, and operational support across commercial-order and product-restriction systems.

I co-developed a self-service CDN image-management solution for approximately 8,000 stores, reducing image-upload support tickets from at least two per week to zero. I also eliminated recurring failures in a regional application and built monitoring, health-check, diagnostic, and remediation tools for multiple services.

Across retail, e-commerce, banking, and manufacturing, I've delivered Java and Spring solutions, modernized POS platforms, and mentored teammates. I also build AI-assisted engineering workflows with specialized agents, GitLab CI/CD, CodeRabbit, and automated quality checks.
