Summary
🤩
Rockstar🎓
Top SchoolYehor Masiuk is a Ruby on Rails developer with nine years of engineering experience and over three years focused on back-end Rails work, currently building products at Axon from Kyiv. He has shipped features end-to-end and revived legacy systems across startups and open-source crypto platforms, contributing notable refactors and infrastructure integrations for OpenDAX and Peatio. Yehor blends back-end craftsmanship—clean, reusable code and Sidekiq-based background processing—with hands-on DevOps changes such as Envoy gateway and service configuration. He’s comfortable moving between Rails internals and front-end theming, having also implemented UI styling and design-system tweaks in OpenDAX. Customer-oriented and results-driven, he pairs reliability with continuous self-learning through courses and articles. An understated strength is his experience removing technical debt in production systems, improving maintainability while preserving delivery velocity.
