Brand
Everything you need to mention me or my packages — on a conference page, a podcast, a meetup or an article. Take the file that fits, use it as it is, and see how to use it first.
Mark
The FK monogram. White on black is the default; the others are for backgrounds it does not suit.
Wordmark
The handle set as code, on its own — for a header, a footer or anywhere the mark would be too small to read.
Lockup
The mark beside the wordmark, for wherever there is room for both.
Avatar
Use it where a speaker or an author needs a picture: a schedule, a guest list, a byline. It stands for me — never make it the profile picture of another account, and never put it next to work that is not mine. The mark sits inside the circle most sites crop avatars to.
Colours
The site's tokens, in the dark theme it opens in and the light one.

Filip Krzyżanowski is a backend engineer working with PHP and Laravel.
Filip Krzyżanowski is a backend engineer in the Laravel ecosystem who builds Laravel backends and maintains the open-source PHP packages behind them — documented, tested and shipped through CI.
Filip Krzyżanowski is a backend engineer in the Laravel ecosystem. The work splits in two: building products and keeping them alive — Dead by Stats, a statistics tracker for Dead by Daylight players, has run for five years and four rewrites — and going into existing codebases to make them faster with N+1 fixes, indexes and caching. PHP and Laravel sit at the core, with FrankenPHP, Redis, MySQL and Docker around them, and nothing ships until the test suite is green. Filip publishes open-source PHP packages, documented at docs.fkrzski.dev.
Usage
Do
- Start from white on black; pick another version only when the background asks for it.
- Scale it evenly and leave room around it — at least a quarter of its height.
- Link to fkrzski.dev where the medium allows it.
Don't
- Recolour, stretch, rotate, outline or add effects.
- Redraw the wordmark in another typeface.
- Set it on a busy background it does not stand out from.
The mark, the wordmark and the avatar identify me and my work. Use them only to refer to me or to something I made, and never in a way that suggests I made, endorse, sponsor or am part of something I am not. Unsure? Write to [email protected].
