My name is Szymon. I am a software programmer and this is my personal website. I created it to simplify contact with potential employers and as a way to tell people who I am and what I can do for them. You’ll find here many of my articles, galleries with pictures about some of my travels, samples of my programming work and job-related information. Unfortunately I was able to translate into English only the most important elements. If you speak Polish (which is my native language), you may want to switch into it to get more content. I wish you a pleasant reading.

Hire Me as a Programmer

I have more than 10 years of experience in creating complex software solutions for the top companies. For several years I have been self-employed and have been working on contracts usually for American or West European companies. I am also open to remote work. I take pride in being a very effective, practice-oriented person. I love working in dynamic, agile teams which make full use of my skills, high motivation and an ability to find elegant solutions to complex problems.

My skills are concentrated around software development and project management with particular emphasis on C/C++, Rust, Python, web stack (HTML5, CSS, JavaScript)  and agile methodologies like Scrum or Kanban. I specialize in low-level programming related to electronics, telecommunications, real-time or high-load systems and finances.

Synchronous vs Asynchronous IO Operations

Due to a growing complexity of software systems, there is a natural tendency towards simpler methods that achieve similar (although not identical) results. Examples include Java or C# language. This process highly relies on removing the need for understanding complex operations that take place inside your operating system kernel. a Programmer is only supposed to combine prebuilt components into his application. This “idiot-friendly” solutions often lead to dramatic decrease in you application performance.
