Hey, I’m Erwin James.
From messy workflows to working software.
I build business applications, automate workflows, and turn AI capabilities into practical tools. My work connects full-stack development, cloud architecture, and AI grounded in the information people need to get things done.
Selected work
From shared business APIs to AI-assisted email operations: three case studies in building software around real workflows, reliable data, and clear responsibilities.
When AI Accelerated Development, Architecture Became the Bottleneck
Consolidating four Next.js backends and two databases behind a shared API for customer, pricing, and transport workflows.
Designing a Cost-Conscious Serverless Platform on AWS
Usage-based infrastructure and managed livestreaming for a deliberately small multi-platform product.
AI-Assisted Email Operations
Combining LLM interpretation, knowledge retrieval, customer context, and validated pricing to prepare responses for human review.
I’m Erwin James
Lead Software Engineer. 3× AWS Certified. Working across software, cloud, and practical AI.
I work directly with business stakeholders to understand their workflows and turn requirements into working software. That includes building AI features with LLM APIs, connecting business systems, and taking applications through production deployment and support. I also use Claude Code and Codex in my development workflow, alongside hands-on architecture and implementation work.

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.

3D printing
Printing things I probably don’t need. Calibrating things I definitely don’t.
- 02
RC cars
Tinkering, tuning, and occasionally repairing whatever I just tuned.
- 03
Anime
Long-running series, strong opinions. (Usually skipping the openings.)
- 04
K-pop
Keeping up with comebacks. Yes, I have a bias.

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