About me

in a couple of sentences… or more

My name is Dmitry Sharabin, and I have been a front-end web developer since 2018. Most of the time, I work with Lea Verou on open-source libraries and tools that web developers use every day. Besides that, I build web apps and websites for clients.

I’m a strong advocate of open source and contribute to many open-source projects, including Prism, Color.js and Color Elements, hTest, Nudeps, Style Observer, Mavo (which I’ve been passionate about since 2019), and many more.

I love building things with HTML, CSS, and vanilla JavaScript, and I reach for Angular when a project needs something more complex. I’m a huge fan of RxJS, Taiga UI, and Firebase, which I find excellent tools for the job.

I use AI coding agents in my daily work and don’t hide it. They let me spend more time on design and product decisions, but I still read every line they write.

I have also taught computer skills to people of all ages for more than two decades. I am an expert in Microsoft Office (MOS Master and Office 2019 Expert) and a former Microsoft Certified Trainer (2020–2023).

I enjoy sharing knowledge, helping people solve problems and achieve their goals, writing code, and designing.
