Über mich
I am John, a senior Ruby on Rails engineer with 16 years of Rails experience and 20 years building software products.
I help SaaS and product teams fix production bugs, build focused features, integrate APIs, improve performance, and add practical AI search features.
My background includes marketplaces, payments, booking systems, healthcare, real estate platforms, PostgreSQL, Redis, Sidekiq, Stripe, React, React Native, AWS, and production Rails APIs.
I work best with existing Rails apps where clear debugging, careful implementation, and practical delivery matter.
