About Me

A backend engineer with a product mindset, comfortable owning features end-to-end — from design and implementation to performance and reliability.

Over the past decade, I’ve worked with distributed teams to build and maintain production systems for messaging, learning platforms, and online content products. I’m most at home in Ruby on Rails, but I’m equally interested in understanding the product side and collaborating closely with designers, PMs, and other engineers.

I care about clean, maintainable code, thoughtful APIs, and pragmatic engineering decisions. In past roles, I’ve led messaging teams, improved background processing with Sidekiq, and helped introduce Agile practices for better delivery and communication.

  • 14+ years of professional experience with Ruby on Rails.
  • Comfortable working remotely with international teams.
  • Experienced in performance tuning, background jobs, and API integrations.
  • Enjoy mentoring juniors and improving team practices.
