Cloud & DevOps Portfolio

AWS infrastructure projects focused on scalability, automation, monitoring, Infrastructure as Code, and cloud engineering workflows.

About

Former product designer with a background in systems thinking, research, and cross-functional collaboration, now transitioning into cloud engineering through structured hands-on AWS builds.

Over the past two months I’ve gone from launching basic services to designing multi-tier architectures like custom VPCs, NAT Gateways, Application Load Balancers, and Auto Scaling Groups. Every project is documented publicly on GitHub and LinkedIn, including what breaks and why.

Currently preparing for AWS Solutions Architect Associate Certification. Open to cloud engineering and cloud operations roles in the U.S. market.
