What I'm looking for

I'm available for international roles where I can build and operate scalable Node.js, TypeScript, and AWS serverless systems, drawing on four years of fully remote collaboration with a US-based team.

Software engineer focused on building systems that stay simple even when the scale isn't.
For the past four years, I’ve worked remotely with a US-based team at Inveterate, a Shopify-native loyalty platform serving millions of customers across thousands of stores. I worked across backend development and infrastructure on an event-driven AWS architecture using Lambda, EventBridge, SQS, DynamoDB, and CDK. I also helped improve the customer ingestion pipeline so large merchants with millions of customers could onboard reliably.

Before that: five years of full-stack work for the Japanese market, from Ruby on Rails to a first fully serverless backend.
