Top SchoolVitaliy Nahaylo is a Senior Ruby Developer with over 14 years of hands-on experience building and architecting production-grade web platforms from Lviv, Ukraine. He has led teams, mentored engineers, and created systems end-to-end—frequently collaborating directly with CEOs and cross-functional partners to align technical work with product goals. Notable achievements include orchestrating a Rails 5→6 upgrade, migrating 20TB from Paperclip to ActiveStorage, and implementing PostgreSQL and monitoring optimizations to reduce load and costs. He blends backend craftsmanship (Ruby/Rails, PostgreSQL, Redis, Sidekiq) with DevOps-minded automation for CI/CD and deployment, having worked closely with infrastructure teams for many years. Comfortable in both startup and product environments, he has a track record of building resilient, measurable systems that scale. Colleagues describe him as a pragmatic problem-solver who prefers tackling the full lifecycle—from architecture to deploys—rather than only isolated features.
