Dmitriy Kovalenko is a Ukrainian developer who built and maintained the date picker components for Material UI, including the date-io abstraction layer that unified every major JavaScript date library behind a single API. He has since shifted to performance-critical systems work in Rust, SIMD-optimized C, and WebAssembly, and currently works at LightSource.ai.
Tools
SIMD-accelerated image-comparison library with Node.js bindings for fast pixel diffs in visual regression tests.
Cypress plugin that fires native system events, enabling hover, drag, and other OS-level interactions in tests.
POSIX- and glibc-compatible globbing library for C, Zig, and Rust that outpaces glibc and supports gitignore syntax.
Open-source DIY CO2 sensor build with a ready-made TUI that alerts when it is time to ventilate.
Abstraction layer over JavaScript date libraries, exposing one API across Moment, Luxon, date-fns, and Day.js.
ESLint plugin that sorts and groups JavaScript imports into tidy, consistent file headers.
Terminal browser for Bluetooth Low Energy devices: scan, inspect, and interact from the command line.
HTTP server written in under 200 lines of pure assembly, plus an experimental React Server Components implementation.
Collapses the import block at the top of any file automatically, using Treesitter inside Neovim.
Neovim plugin that holds caps lock for a single word, making SCREAMING_SNAKE_CASE identifiers easier to type.
