Hey, I’m Erwin James.

Code is cheap now. Coherence isn’t. Let’s make it hold.

I build software, design cloud architecture, and put agentic AI to work automating the parts of a business that shouldn’t need a human.

Selected work

Three systems, three different constraints. Each one is a case study in making independently useful pieces behave as one product.

01, Platform architecture

When AI Accelerated Development, Architecture Became the Bottleneck

How clearer boundaries and shared business authority helped a growing application estate stay coherent.

02, Cloud infrastructure

Designing a Cost-Conscious Serverless Platform on AWS

Usage-based infrastructure and managed livestreaming for a deliberately small multi-platform product.

03, Operational AI

Making AI Useful Without Making It Authoritative

Probabilistic interpretation surrounded by explicit rules, authoritative facts, and human judgment.

Hey — I’m Erwin

About

Lead Software Engineer. 3× AWS Certified. Based where the product, the infrastructure, and the business rules meet.

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 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 across product, platform, and cloud.
Certified.
3× AWS Certified, with a bias toward usage-based, cost-conscious infrastructure.
Interested in.
Cloud-native infrastructure and practical AI with clear boundaries and bounded authority.

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.

  1. 01

    3D printing

    Printing things I probably don’t need. Calibrating things I definitely don’t.

  2. 02

    RC cars

    Tinkering, tuning, and occasionally repairing whatever I just tuned.

  3. 03

    Anime

    Long-running series, strong opinions. (Usually skipping the openings.)

  4. 04

    K-pop

    Keeping up with comebacks. Yes, I have a bias.

  5. 05

    The hamster

    Head of morale. Accepts pets on demand. Currently furious about something.

Let’s talk

Let’s make it hold.

I’m always happy to hear about an interesting product, an awkward workflow, or a system that needs a little more clarity.
