Programmer • Coach • Trainer
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.
Szymon Wieloch
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.

Do you have a difficult project and don’t know where to start? Do you need to choose from a huge set of technologies and languages and you just don’t know enough details to choose the best one?
The IT world is becoming more and more complex as new languages, databases, patterns and methodologies are being developed. No doubt that navigating through all of them can give you a headache. During my 10+ years of work in multiple projects I have gained broad experience in almost all most popular IT technologies. This knowledge allows me now to help you with your project. I provide both consulting and application design services that will allow you to easily start even a very complex project. Interested?

For many years C++ language was the only reasonable option for writing real time or embedded software. But during recent years a new technology has emerged. A technology that has potential to take the crown of low level programming in several years. It’s called Rust.
The following are commercial projects I took part in during my career:
Certificates that I received after exams or during trainings in a variety of martial arts courses. Mainly Krav Maga.
In the age of multiple available operating system a programmer often faces a problem of choosing the platform for his project. This choice is often not trivial. Sometimes certain functionality is available only on selected platforms, sometimes user tastes change and they migrate from one platform to another (for example Symbian was dropped because of huge interest in Android), many application are written for multiple platforms from the beginning. It is often best to write code that is platform independent and if that is not possible – to somehow manage existence of multiple platforms in the most simple way.
Modern IT world has created hundreds of programming languages. Each of them has its own pros and cons. If you have a job to do – what language should you choose?

In 2018, after more than 7 years of training, I finally passed the black belt exam and became one of very few martial arts experts in Poland.
More and more of programmers’ interest is attracted by so the called agile project management methodologies. And there is a good reason for that because research done in USA showed that projects using this approach get better ROI.
In one of my previous articles I have described the idea of asynchronous operations. Apart from many advantages asynchronous operations do have some disadvantages as well – they are complicated. It’s relatively complicated to implement a big, multiplatform application. Of course, it is possible to wrap native functions from your operating system with classes that will highly simplify the use of this complicated approach and they also can hide the inter-platform differences. Correct encapsulation and abstraction can result in a much more user-friendly interface.
Moasis is a project that was created from scratch by me and only me. Additionally it became a huge commercial success.
