Marat Dulin mdevils

Hi, I'm Marat — a dedicated open-source developer passionate about creating efficient and developer-friendly tools.

My Focus Areas:

Developer Tooling: My projects often revolve around enhancing developer productivity through tools that simplify complex tasks. I'm currently actively contributing to Biome, a next-generation JavaScript and TypeScript linter and formatter that aims to provide a comprehensive solution for modern web development.
HTML Entity Handling: I maintain html-entities, a robust library for encoding and decoding HTML entities, widely used in web development projects.
CSS Selector Parsing: I created css-selector-parser, a library that provides a fast and efficient way to parse CSS selectors, making it easier to work with styles in web applications.
TypeScript Exercieses: The most popular set of TypeScript exercises, designed to help developers learn and practice TypeScript concepts effectively.
Rust crates: I developed osakit, a Rust interface to macOS's OSAKit framework, enabling seamless execution of AppleScript and JavaScript through native bindings.

Previous Contributions:

JSCS: A JavaScript Code Style checker that was widely used before being merged into ESLint.
ENB: A pre-webpack era build tool for JavaScript projects, which I've developed and maintained for several years.

Why Open Source?

I believe in the power of collaboration and the open-source community's ability to drive innovation. By sharing my work, I aim to contribute to a more accessible and efficient development ecosystem.
