Ladislav Macoun

Software Engineer



Hi, my name is Ladislav, I have more than 5 years of experience in software development. I started as a researcher at CESNET during my college years at CTU. I worked at Rockwell Automation in the R&D in security toolkit team. Where I worked on secure protocols and tools for embedded systems. Currently, I challenge the speed of light in the CDN77 where I work on speeding up the internet as a software engineer developing software components and tools for handling more than 30+ Gbps traffic.

I love to code, especially using GoLang or C.

Experienced with modern and effective C++ (C++11/14), also with MISRA coding standard.


Go is currently my favourite language to use, loving the simplicity, yet complex systems can be developed pretty fast. Having multiple production services written and running in golang.


Experienced with high performance luajit.


Still have a lot to learn, however, rust is becoming my top pick for developing new high performance and reliable software.


Fluent with Java, not my usually goto language but had some projects in it. Mostly known from literature such as Clean Code or Head First Design Patterns.


My goto language for more complex scripting which is difficult with bash or fast prototyping.
