Senior🎓
Top SchoolDenis Peplin is a seasoned backend engineer with 14 years of experience, currently focused on Elixir and building resilient services from Volgograd, Russia. He has deep hands-on experience with Elixir/Phoenix ecosystems—GenServer, GenStage, supervision trees, Phoenix PubSub—and has tackled complex async IPC and per-user distributed queues in production. Prior work spans Ruby on Rails and PostgreSQL, including improving backend maintainability on an open-source Rails ecommerce project and fixing a production search implemented in pure Postgres. Denis combines systems-level instincts from an earlier networking and sysadmin background with rigorous TDD habits developed over long-term remote collaboration. Comfortable both in microservice and monolith environments, he prefers shipping reliable backend features and digging into low-level data and concurrency issues.
