• My name is Richard Ivánek and for some time now (around 14 years, 8 professionally) I code. My primary languages are Rust, TypeScript and C#, but I also do C/C++, Haskell and Dart occasionally. I have a master's degree in theoretical physics, which I studied in the Faculty of Mathematics and Physics at Charles University in Prague.

    I've programmed professionally since my high school years. I've been self-employed since my university years and I've been working on several long-term (and a few short-term) projects.

    I do all sorts of software development, I work with modern technologies (WebAssembly with Rust, WebGL, Svelte, Axum), distributed systems (Kubernetes, OpenShift), and even older technologies (Shoptet with jQuery). More details below.

    Programming languages

    4 years


    My favorite, I even wrote the code for my master's thesis in it.

    6 years


    My second most used language, I use it with several backend and frontend frameworks.

    13 years


    My first "real" language. I used to create games in it. Then I moved to web and CLI applications. Now I even do Office COM Interop and Microsoft Graph API clients in it.

    2 years


    I don't use these daily, but I refresh my knowledge of them from time to time to keep up with FOSS code.

    Dart + Flutter

    My and my colleagues shipped an iOS/Android app, but I don't see a future in this ecosystem.


    8 years


    I daily drive it since Windowsu 10 released (yes, there's causality). I even admin a few Linux servers with RHEL derivatives such as AlmaLinux. Btw I use Arch.

    8 years


    I use it for all my projects. I love it when it works, I am terrified of it when it gets in a state that's not easily recoverable, which thankfully doesn't happen that often anymore.

    2 years


    I utilize them both as a user and a developer, for distribution and deployment. I shipped a few Node and Rust projects with it. I also do Docker Compose.


    I've been using these for a relatively short time as of now, primarily to satisfy client requests.

    Frontend frameworks

    2 years


    My beloved, even this site uses it (the alpha version of Svelte 5 actually, I have no idea what "unstable" means).

    6 years


    I don't use it that often anymore, but I have to admit the recent development looks promising, so who knows.


    I work around it on Shoptet instances, but recently my work was to get rid of it and replace it with several browser APIs.

    Backend frameworks

    1 year


    I often use it to create performant backends.

    1 year


    I used this before moving to Axum.

    5 years

    ASP.NET Core

    I have written many backends in it, nowadays I use it mostly in older projects which I still maintain.


    I maintained an Angular + Nest app. Not a biggest fan, but I understand why it's widely adopted.



    One of my favorite FOSS projects. I have some hours spent in it and I've also read a bigger chunk of it's codebase.

    5 years


    Frameworks that I literally grew up on. They helped me become a decent programmer.


    I experiment with it from time to time. I wrote an application launcher in it, which I daily drive for more than a year. I'm looking forward to mobile support.

    This section is for those who are not looking for a CV, but rather just want to know more about me. I began programming in the sixth grade, when my classmate brought a calculator with BASIC support to school. My interest led me to a variant called Small Basic, with which I spent a lot of my free time home. I built a few text-based RPG games, but soon I began to feel limited by the language. So I then learned Visual Basic and WinForms, but that still wasn't quite it. I wanted to create real games, so I went with C# and XNA. I still have some of the early projects I tried with this language at the age of 13.

    I kept using C# primarily until my university years, I prototyped a lot of games, but I always got bored of them in the end. In the meantime between projects, I learned web development, which is one of my primary sources of income these days. I originally worked with PHP and JavaScript, but soon I moved to ASP.NET and TypeScript. Today I barely use C#, I moved to Rust, in which I wrote my master's thesis program. Today I work on CLI deployment tools, high-performance applications, data processing programs and e-commerce process automation. I try to design web stuff from time to time, so I might still have some fun with this website ;)
