About

My portfolio (Website not available. Sign in: https://www.twine.net/signup

I’m Daniil, a front-end developer who enjoys building responsive, semantic web interfaces with HTML5, CSS3/Sass, and JavaScript. I work with layout systems like Flexbox and CSS Grid, manipulate the DOM, and use Node.js as part of my everyday workflow.

My background also strengthens my approach to problem-solving: I’ve practiced algorithms and data structures through coding challenges and course work, and I enjoy turning these skills into clean, maintainable UI. From API integration and REST work to Git/GitHub collaboration, I focus on delivering solid user experiences and practical, real-world results.
