Krylan | Krzysztof Koperkiewicz
I'm Krzysztof Koperkiewicz and I'm a web developer. My curiosity and ambition make that HTML, CSS or JavaScript holds no secrets for me. Backend technologies like PHP or MySQL aren't also unfamiliar for me. I'm making websites on my own, starting with graphics project – for this purpose, I'm using Adobe Photoshop software. Other graphic works I'm making, includes icons or logos, are designed in vectors with Inkscape software.

Aside from websites, I'm interested in composing songs and drawing manga-inspired illustrations. I'm gaining knowledge from other fields or software capabilities like the 3D graphic (Blender) or movie editing (Adobe After Effects).

Areas, in which I am developing


All my projects are optimized and tested in terms of performance, as faster website is better user experience.


I'm using tools to design and prototyping UI/UX, which aligns great with technical front-end knowledge.


I'm learning new ways of creating and adapting content for as many people as possible, i.a. considering guidelines from WCAG.


Working in SEO branch taught me a lot on what to take into account, to make website better for search engine bots.


Except creating a website, I can also correctly deploy it and configure a server.

Cyber Security

I know how important is security, thus I'm regularly reading branch articles and learning about tools for discovering vulnerabilities on websites.

Web development mentoring

In my online activities I'm rather often sharing my knowledge with others. It's something I love to do and people, who I'm helping, are calling me a good teacher. If someone would like to get knowledge from web development or learn basics of software I'm using, I'm open for contact.
