About me

नमस्ते ।   My name is Jakub Mareček. I am interested in programming using C#, JS, PHP and apps for Android and for Windows in C++. Also a something for Arduino and Raspberry Pi.

I started programming when I was 11 years old. My first program or script was simple 'Hello world' in Windows batch file.

That wasn't enough for me. So I decided to look something more. Then I found Visual Studio. I learned my first programming language Visual Basic .NET.

Some years later I started learning Visual C# because I was interested in 3D game programming, but I gave it up and started with C++ and Java programming. I selected Java because I wanted make apps for Android operating system.

And I successfully created my first Android app 'Notes' (see here) where you can write and save notes and give them color or place them as widget.

Last years I am interested in programming Arduino and ESP8266 microcomputer.

I am also making 3D models and maps for PC game Arma 3 as my hobby. You see some my work below.

I have my own web/file/media server build on Raspberry Pi and my computer network is based on MikroTik RouterBOARD.

My other hobbies are astronomy, photographing and also making mod for PC games.


In my free time I am learning Nepali language as my hobby, म नेपाली थोरै बोल्नसक्छु । नेपाली भाषा सिक्न थालेँ किनभने म नेपाल भ्रमण गर्न चाहन्छु ।


My favourite singer is David Bowie (R.I.P.), singers of Bollywood, also some from Creedence Clearwater Revival. And I also like soundtracks from games.


I like also photographing. Here you can see some of my photos.


I am interested in astronomy so I decided to start taking photos of universe.
