What I'm looking for

I seek cloud-focused roles where I can design secure, scalable AWS infrastructure, drive DevOps improvements, mentor teams, and deliver measurable business impact within collaborative, engineering-driven organizations.

I am a passionate cloud administrator and engineer with over 20 years of experience designing, developing, and maintaining mission-critical software and systems. I specialize in AWS architecture, infrastructure-as-code, DevOps practices, and secure, scalable cloud solutions.

I have led cloud and modernization efforts across public and private sectors, including healthcare, insurance data services, and state government, driving measurable business outcomes such as a 22% revenue increase for a product team in 2023. I hold AWS Solutions Architect Professional, AWS DevOps Engineer Professional, and CCNA certifications.

In hands-on roles I design and deploy Terraform-driven infrastructure, implement serverless and container solutions, and automate operations with Python and Bash. I also strengthen CI/CD pipelines using GitHub Actions and Jenkins and monitor production with Datadog and CloudWatch.

I contribute to the community through consulting (Amazon IQ), blogging at hamacher.cloud, and maintaining public serverless projects. I am known for attention to detail, accountability, and the ability to persuade stakeholders to adopt effective technologies.
