I help US companies ship features, fix production issues, and keep complex systems running reliably. Over the last 10+ years I've worked across the full stack for US-based companies, from Rails/Grape APIs and React frontends to Shopify integrations, payment gateway extensions, and high-traffic e-commerce platforms (12M+ monthly requests, 15,000+ merchants in production). Recent work includes: - Senior engineer at Acima Leasing (Rails, TypeScript, React), owned WooCommerce and Magento plugins in revenue-critical production environments - Led platform migration at ND2A Group, PHP → Laravel, 30GB+ data migration, AWS Lambda APIs, 12M+ req/month architecture - Built Shopify admin tools, manual order systems, and React/Redux frontends over 5 years I'm comfortable jumping into existing codebases, improving legacy systems, and working across the stack without handholding. Core stack: Ruby on Rails, React, TypeScript, Node.js, Laravel, PostgreSQL, AWS, Docker Also strong in: Shopify / WooCommerce / Magento integrations, CI/CD, RSpec, Jest, Playwright US Citizen.
