What I'm looking for

I seek remote-first, product-driven roles where I can build scalable systems, improve architecture and developer workflows, mentor teammates, and contribute to mission-driven teams.

I am a remote-ready full-stack software engineer specializing in back-end development with deep expertise in Ruby on Rails, RSpec, Minitest, Hotwire, JavaScript, SQL, React, and TailwindCSS.

Since 2019 I have delivered scalable, maintainable products aligned with business goals across distributed teams and async workflows, contributing to major migrations and feature designs for EdTech and SaaS platforms.

Key achievements include migrating a flagship EdTech certification product, designing a Nested Accounts multi-tenancy solution using Ruby monkey patching and gem customization, and building an internal lightweight video review platform to improve non-technical team workflows.

I thrive in product-driven, remote-first teams that value autonomy, clear communication, clean code, and continuous improvement, and I enjoy mentoring peers while improving performance, test coverage, and system architecture.
