Hey, I’m Erwin James.
Software gets complicated.
Let’s make the pieces fit.
I work across product development, cloud infrastructure, and practical AI—usually where software has to match how a business actually works.

About
I’m a software engineer who enjoys understanding how a product really works—not just the code, but the decisions, workflows, and constraints around it.
I’m especially interested in cloud-native infrastructure and practical AI. I like getting into the details, untangling the messy bits, and building systems that stay clear as they grow.
Currently working as a Lead Software Engineer.
3× AWS Certified.
Away from the screen
Outside work, I’m usually 3D printing something I probably don’t need, tinkering with RC cars, watching anime, catching up on K-pop, or petting my hamster.
