Scripting
#

Started with Luau back in early 2017, and since then, I’ve gotten pretty good at OOP and different frameworks like Knit (RIP). I also use modules like ProfileService, Promises, and Maid a lot.

TypeScript
#

I’ve worked A LOT with RobloxTS , Flamework , and other libraries like React-lua, Rodux, and Maid. I use these regularly in my own projects and for games I work on.

Debugging & Performance Improvements
#

I do enjoy optimizing and improving code, so I’ve spent a lot of time working with Parallel Luau and debugging tools like the MicroProfiler and LuauHeap. I can track down memory leaks, fix performance issues, make reports, and consult on game performance.

Exploit Prevention
#

Got a ton of experience designing and testing anti-cheat systems as well as making sure games are secure.

UI
#

Been improving my UI design skills over the years. I have experience with React-lua and Fusion.

Translations
#

Native Czech speaker, so I can translate texts or entire projects between English and Czech.

Programming
#

Besides Luau, I’ve worked with JavaScript, TypeScript, C, C#, and even a bit of Assembly.

System Administration
#

I’ve got hands-on experience with system and network administration, managing both personal and production servers. I also run a Czech Minecraft semi-vanilla server that sticks to the “old-school” Minecraft feel.

Tooling
#

Among other stuff I do have experience setting up automated code testing, working with git, automatic code code deployment to Roblox, and other stuff.
