Summary

Developer and cloud infrastructure engineer with 10+ years of experience building applications on AWS and Azure environments for engineering and environmental clients. Comfortable writing full-stack code in the morning and infrastructure-as-code tooling in the afternoon. Strong track record in CI/CD automation, cost optimization and security hardening. I like building clean, repeatable, well-documented infrastructure and earning buy-in across teams. As a developer, I aim for applications that clients not only like to use but feel involved in.
