Software Engineer
David Rohweder
I’m a software engineer who likes building reliable, well-tested systems end to end, from cloud infrastructure and CI/CD to the product people actually use.
About
I’m a software engineer at Iridium, where I build automated test suites, CI/CD pipelines, and full-stack applications that operate over a global satellite network. I care about clean systems, fast feedback loops, and tools other engineers actually want to use.
I’m AWS and Terraform certified and currently pursuing graduate studies in computer science at Georgia Tech.
Outside of work you’ll find me hiking the Southwest, training Muay Thai, or chasing good food somewhere new.
