Ember.js & Rails Architect - AI-oriented

Ember.js & Ruby on Rails developer · technological partner I build and own production Ember.js and Ruby on Rails apps. Since 2017 I have thousands of commits as the primary author on the Ember side of a multi-tenant SaaS, plus ongoing Rails work on the same product. I am also an Ember.js open source contributor. I have worked remotely for 10 years, async, with teams around the world (mainly USA today). I care about KISS: simple designs, clear patterns, no unnecessary complexity. I clean things up and leave systems easier to maintain than I found them. I use modern AI tools to move faster. For sensitive work I run local AI on my MacBook Pro with 128 GB RAM (antirez ds4 + DeepSeek V4 Flash), so private context stays on the machine. I still own the review and the merge. You hire judgment and reliability, not raw code volume. Punctuality, clear communication, and follow-through matter to me. Good cooperation means both sides are satisfied. Open to serious paid partnerships: ongoing ownership, modernization, or focused delivery on Ember + Rails.
