Portfolio

My name is Norbert,
I'm software developer specialized in building high performance, large scale, web applications.
I live in Cracow, Poland - in case you would like to get in touch or grab a beer/coffee.
Since Nov 2015 I'm working as a software architect & team leader in Mohawk Group (NASDAQ: MWK) building fully automated Supply Chain Engine.
Most of the projects I worked on, were written in PHP or NodeJS but I also did some cool things in Scala or even C.
I'm fascinated in all technologies related to web development, because of that I'm actively designing, developing and maintaining web infrastructure for projects I participate in, with tools like Terraform, Ansible and Packer.
At this point I'm more Azure Cloud oriented but using mostly Open Source stack to avoid vendor locking.

I also run a technical blog, mostly PHP oriented, if you can read in Polish or if you don't mind using
google translate check zawarstwaabstrakcji.pl (πŸ‡ΊπŸ‡Έ translated version).

Visit project documentation page to learn more and don't be worry about time anymore!


# MD Link Linter Open Source

PHP CLI Tool License: MIT

CLI app that iterates through all markdown files in given path checking if links used in them are always valid. I become obsessed about improving developer experience in projects I'm working on. Most of my projects is documented in markdown syntax since it's easy, can be easily converted to HTML but event without that it's still human readable. Keeping url's up to date was always my biggest nightmare, that's how MD Link Linter was created.

In order to make it even more flexible I created docker image that can be used just like in example below:

docker pull norberttech/md-link-linter
docker run -t --rm -v $PWD:/app norberttech/md-link-linter --exclude=vendor --exclude=node_modules .

Those 2 simple CLI commands can be executed at any operating system with Docker installed. First one will download the image, second will execute it in the current folder, passing additional arguments to exclude `vendor` and `node_modules` folders from inspections.


# Structurizr PHP Open Source

PHP Library License: MIT

If you are familiar with C4 model by Simon Brown then you already know what this library is for. In other case you should watch this talk:

# PHPMatcher Open Source

PHP Library License: MIT

PHP library that only job is to match values against patterns, extremely useful when you need to check if API response matches expected pattern for example in functional tests. It also provides many useful placeholders like for example @string@ or @number@ that makes it even more powerful.

Still not convinced?
You can test it before using at https://php-matcher.norbert.tech!

Sandbox source code is available at coduo/php-matcher-site


# AssertJS Open Source

JavaScript Library License: MIT

This is nothing more than another JavaScript Assertion Library, but it comes without any dependencies. It's strongly inspired by assertion libraries available in PHP. It was initially developed as a part of No Game - JS 2D Multiplayer Game Engine and extracted to standalone repository later.
Using assertion makes development much more offensive, with minimum tolerance for mistakes but maximum verbosity of errors.

Introducing EventStorming

At first look, EventStorming is deceptively simple: just have a long paper roll available, and a virtually unlimited stock of coloured sticky notes and start modelling problems that looked too big to be modelled. But the ability to visually mastering large scale complexity opens the way to many interesting outcomes.
