Hello, I'm Aleksander Chortyński, widely known as
Sprawdzany
About
I am year old full-stack developer from Poland, and I care about building things that survive real traffic, messy data, and the moment someone actually uses what you shipped. I like going deep on a product end to end, from rough ideas to something you can deploy and iterate on. Innovation, for me, is not a slide deck. It is the habit of reaching for problems and tools I have not touched yet, learning quickly when the first version breaks, and shipping the next one with fewer excuses. If there is a stack I have not tried, a domain I have not poked at, or an idea that sounds half-reasonable once you write it down, I will probably want in.
