Know your contractor

Programista PHP Poznań

Krzysztof Król

Frontend developer and SEO specialist. I live and work with essentialist approach.

I have experience in creating websites and their positioning. I focus on web development, developing PHP, JS and ASP.NET Core.

If the project does not require the precision of Photoshop, I use free software. The way of my work constantly strives to contribute to the development of open source in Poland and in the world.

In work and in private life I put on the meticulousness and quality of actions, rather than the number of projects. This attitude promises to challenge me, which fills me with joy completion and fulfillment.

I run a blog about web programming - in so far as I can help people in my step or a few steps behind me - and the life of the essentialist approach, with an emphasis on crossing patterns mentality and habits.
