What I'm looking for

I'm open to remote, worldwide opportunities where I can lead delivery across e-commerce platforms and internal tools, improve engineering standards, and build scalable TypeScript, React, Remix, Shopify, and AWS solutions.

At AlumierMD, I lead delivery across four interconnected codebases and four Shopify storefronts serving 17 countries. I’ve replaced third-party loyalty tooling with an in-house solution, built a React and TypeScript marketing platform, and supported a parallel migration from Ruby on Rails to TypeScript and Remix.

I set engineering standards that improve team delivery, including code review and documentation practices. I’ve authored 180+ pull requests and completed 100+ peer reviews across six repositories in H1 2026, while introducing AI-assisted code review, shared knowledge, and CDK-based Lambda deployment tooling.

Previously, I delivered full-stack Rails platforms, managed data pipelines and reporting, and built test coverage across e-commerce, consulting, and financial-services environments.
