AWS Cloud × DevOps × AI Platform Architect
Enterprise AWS infrastructure with Terraform, CI/CD, and AI platforms.
I architect and deliver secure, scalable AWS platforms using Infrastructure as Code (Terraform), automated CI/CD pipelines, and DevOps best practices. From zero-downtime migrations at Mercedes-Benz to self-service cloud platforms, I enable teams to ship faster while maintaining security, compliance, and cost efficiency. I enhance infrastructure and security for AI platforms—orchestrating AWS Bedrock, OpenAI, and RAG pipelines with enterprise-grade reliability.
