About Me

I am curious by nature. I always want to know how things work. To just use things or talk about'em has never been enough for me. It's about creating things that can change the world we live in. That is why, a long time ago, I decided to learn how to write code using various programming languages and well-known techniques (patterns). I started with Visual Basic at school, then explored Delphi in high school and then dived into .NET with all associated types of apps that could be created at the time. In my thinking, it's mandatory to know some script languages like Bash and PowerShell. Through writing code, I learn the most about anything.

Major: Information Technology and English June 2006

Once, when our English teacher wanted to verify our knowledge of Reported Speech, she gave us over ninety sentences to work with and no more than ninety minutes to complete the task. At that time I felt like it was kind of student's nightmare, but today I do appreciate the whole effort she put into teaching us RS and many other aspects associated with learning English.

Specialty: Operating systems and network administration June 2011

Writing code and working with Linux were my favorite activities throughout this stage. We had a teacher who was so into Unix based environments, that it was a real pleasure to attend each class to learn and admire the man who was so passionate about his work. Once, he gave me a very important lesson by saying that the best men in IT are those who were capable of creating their own tools that could make their and other people's work easier.



.NET Developer (C#) 2009 - Present

My last project required creating a Windows service to communicate with two local MSSQL Servers and a remote REST (json) service. The project was made in cooperation with some very smart people from Instytut Logistyki i Magazynowania and GS1 Polska.

SAS Maintenance team member 2012 - 2013

That is how I started to gain more and more experience of working with the most complex relational database management system - Oracle. I still benefit from the lessons I learned at the time as now I'm responsible for maintening IMPULS Evo at Sokołów S.A. which is based on the Oracle 12c cluster.

Sokołów S.A.

IT Specialist, Infrastructure Services 2015 - present

In a nutshell: every day brings something new. The environment is so big that it's difficult to write and focus on the most important aspects. VMware, Dell storage (iSCSI), Cisco and Hewlet-Packard network equipment, Windows & Linux (including PowerShell & Bash scripting), Active Directory and many others - this is what I deal with on a daily basis working at Sokołów S.A.
It's not worth trying to be good at everything. Find your specialty and stick with it, otherwise you'll soon reach a dead end - lesson learned.

One is naive if thinks they can learn anything at once and be able to implement that knowledge in the same short amount of time. My work approach includes making notes, creating clear manuals for myself and others, sharing my knowledge. I seek knowledge and opportunities to learn. Every failure is a lesson. Every lesson is a bless.
