Oleg Vivtash is a Senior Ruby on Rails developer with about 15 years in software development and 11 years of focused professional experience delivering web and SaaS platforms. He combines deep computer-internals knowledge and hands-on backend expertise—MongoDB, Redis, Resque/Sidekiq, and extensive testing with RSpec and Selenium—to build high‑quality, high‑load services and automation. Oleg has a track record of setting up development processes from scratch, owning feature delivery, tech research and PoCs, and improving infrastructure orchestration with Docker and Ansible. He contributes to open-source Ruby tooling (notably Rackspace support in the fog library) and routinely integrates third‑party APIs and cloud storage in production systems. Equally comfortable with legacy refactoring and new architecture work, he’s interested in cross‑platform projects, IoT and hardware prototyping, which reflects a pragmatic curiosity beyond typical Rails roles. Based in Dnipro, Ukraine, he blends disciplined engineering with a client‑centric mindset to translate business needs into reliable, testable systems.
