Full-stack software engineer Greater Phoenix, Arizona

Edwin Renck.

I build dependable software quickly, from application code through cloud infrastructure.

Open to full-stack opportunities.
Especially with teams solving meaningful, complex problems.

The short version

Software is most useful when the complexity stays behind the experience.

I’m a full-stack engineer who has spent the past three years working on American Express’s business payments platform. My work spans application development and cloud infrastructure, using Kotlin, Java, AWS, and Terraform.

I’m particularly effective at understanding unfamiliar problems quickly and turning them into dependable, maintainable solutions— taking ownership across layers instead of treating each part in isolation.
