Summary
👤
Senior🎓
Top SchoolSergey Shkarupa is a Senior Staff Engineer based in Prague with 11 years of experience building backend-first web applications, primarily in Ruby/Rails and increasingly Elixir/Phoenix. He has led architecture and delivery across startups and enterprise teams—driving APIs, multitenant systems, spatial-data backends, and CI/CD practices at companies like Medallia, Spaceti, and PrimeRevenue. Sergey pairs pragmatic DevOps skills (Docker, Ansible, AWS) with strong test-driven engineering (RSpec, Capybara) and background job expertise (Sidekiq, Redis), enabling reliable production systems. An active open-source contributor (notably to proxes) and GitHub maintainer, he favors Sequel for non-Rails projects and brings hands-on experience with web scraping, GraphQL/REST APIs, and frontend integration (Vue/React). Colleagues describe him as a lifelong learner who balances engineering leadership with deep implementation skills and a curiosity for new languages and architectures.
