Summary
🤩
RockstarEvgeny Karkan is a seasoned iOS developer with 13 years of hands-on experience building and shipping mobile applications across startup and enterprise environments. Based in Kharkiv, Ukraine, he has been contributing to Grid Dynamics since 2017 and previously developed iOS apps and features at Prophonix and Sigma Software Group using Scrum workflows. He blends practical app architecture and feature delivery with a strong foundation in algorithms, evidenced by his EKAlgorithms repository that implements classic search, sort, string and numeral utilities. Comfortable across the full iOS stack, Evgeny has repeatedly taken projects from scratch to distribution while iterating in team settings. Colleagues rely on him for steady execution and clean, testable implementations that balance performance and maintainability. He brings a quiet engineering curiosity—tuning low-level algorithmic components as well as user-facing functionality.
