ABOUT ME

Software Engineer enthusiastic to never stop learning and improving

I'm very enthusiastic software engineer who loves to learn new things and technologies. My passion for software development started in early age and still continues.

I don't want to be restricted by certain technology, so I'm trying to learn as much as possible. I have touched quite a lot of technologies, from assembly, C++, Smalltalk, PHP to JavaScript and Java which I currently use the most.

I'm very interested in software analysis and architecture and I believe knowing as many technologies as I can, will help me to make better and more qualified decisions in that field. I will simply know which technology to use in which case.

In past I worked with vanilla JS and jQuery a lot. Then more modern frameworks came and I worked as frontend developer using AngularJS in one of my past jobs. Now I work with Angular 2+ (currently version 4). I'm a big fan and promoter of TypeScript almost since its beginnings. I also use NodeJS almost every day, so I had chance to get some experience in this field as well. And because I like to learn new things, I tried Aurelia framework for few side projects and I found it very pleasant experience, so I can recommend that framework.

I worked with PHP since my early high school years. I worked on many small projects and later also several full time jobs. In my career I had a chance to work with quite a few frameworks. Namely: Kohana, CodeIgniter and more recently Nette, Symfony and Doctrine. I also worked with major CMS like Wordpress, Joomla, Drupal, phpBB forums and MODX.

I have worked on few projects in C#. Most interesting one was multithreaded web crawler grabbing posts from phpBB message boards and posting them to different ones. I'm a huge fan of C# and I watch its ecosystem and news around that technology. Even though I didn't have a change to work with .NET Core during my employment, I'm following the news and will be more then happy to work on some project.
