Freelance CentOS Developer - Jason White
Freelance CentOS Developer5.0 (182 reviews)

AI Model Engineer, Operating System Developer, Principal Cloud & Infrastructure Architect with decades of hands-on engineering experience and 10+ years designing, modernizing, securing, and operating production AWS environments. I specialize in complex environments where **architecture, reliability, security, and hands-on troubleshooting** intersect. My work has included transforming single-server applications into highly available cloud platforms, designing Infrastructure as Code and CI/CD systems, leading zero-downtime migrations, operating mission-critical SaaS infrastructure, and supporting organizations through significant growth and ownership transitions. Many times I have served as a medium or long term technical consultant and infrastructure owner, working directly with executives, Product, Engineering, QA/Support, and business stakeholders while remaining hands-on with AWS, Linux, automation, security, and production incidents. More recently, I have applied the same production-first approach to AI infrastructure and agentic systems, building secure cloud environments and AI-enabled operational workflows rather than isolated prototypes.
