Summary
👤
Senior🎓
Top SchoolOleg Kostyuchenko is a Principal Software Engineer based in Cork with over a decade of experience building high-performance desktop and Unix-native tools, primarily in C++ and increasingly in Rust. He blends a strong academic foundation in discrete mathematics and formal inference with hands-on EDA work at Cadence, contributing to Cadence Virtuoso and OpenAccess-based tooling. A long-time editor/IDE enthusiast and contributor to the Rust-backed xi-editor, he focuses on rendering, view initialization and editor ergonomics, and has designed optimized typing layouts (Dvorak Symroll) and modal hotkey schemes (Meander). Oleg favors small, composable Unix-style components, text-based UIs and POSIX terminal standards, and brings practical assembler familiarity across x86/ARM. His uncommon combination of deep math background, EDA product experience and obsessive attention to typing productivity makes him a distinctive all-rounder in tooling and developer UX.
