Rostislav Litovkin
Hi! I am
a 20
years old student at Gymnázium Jaroslava Heyrovského in Prague.
(Yes, the age auto-updates on my birthday)
I am into programming unique projects for smart watches.
I am also deeply interested in web3 and all of the technological advancements.
Everything I do nowadays is opensource and I do not want to change it.
See how large my technology stack is. If something is missing, you can be sure that I will be able to learn it, just like I was able to learn all of the others. Learn about my projects, experiences, achievements and hobbies bellow.

My biggest project yet. An easy to learn logic game with a galaxy thematic and complex combinations.
This project started small with just practicing trigonometric functions, but later, on it grew into
something that is updated to this date.
You can try it now for free on Samsung smart watches, Android phones, iOS phones and WearOS
wearables.
Apple App store
Google Play store
Galaxy store (TizenOS)

you need to do in web...
Actively visiting coding events
Visiting conferences and participating at hackathons is important. And meeting new people too.
I gained countless experience thanks to being at (in 2022) Solana Prague Hacker House, Gateway to
Cosmos,
UTXO, DotSama Prague, EthPrague, Solana London Hacker House, The Merge afterparty, DotBrno,
EthBrno, (in 2023) Polkadot Global Series finals, Gateway to cosmos, Nfts in Prague, Polkadot

Mobile port
Aug 2021
Yes, I mainly concentrate on smart watches.
However, that does not mean that I can not port these apps to mobile platforms as well.
The UX/UI is specially optimized for the tall screen, that is so common for mobile, unlike the
circular design found on
smart watches.
Available for both iOS and Android.

I got a challenge to create something for smartwatches with a Paralelní Polis theme. And so I did!
I came up with a unique watchface.
Unfortunately it is not available to public, due to Samsung disapproving my Watchface designer
certificate request.
Computer Science A
Sep 2020 - Jun 2021
Completing this extensive course was also one of the greatest achievements.
It gave me a really solid foundation to coding and it was super easy to follow afterwards with my
personal projects.
I reached the best mark possible in the final exam and was the best student that year who absolved
the course.
First ever Hackathon project
Dec 2020
My whole programming carreer took of from this moment.
After 2 months of active learning of programming, I felt that I could finish my first ever project.
And what better way to start, than on my first ever hackathon.
I did something really risky and tried to programme a simple application for smart watches that
would help you by showing you the times of departures of public transport.
It was very difficult for me at the time, because I did not have much experience with programming
any applications.
I knew only the basics back then. I ended up 4th out of 13 teams and the project got fully working a
few months after.
Sadly, I am unable to provide you the app due to legal issues. It is for personal use only.
Modern flappy animals
June 2021
A simple flappy bird inspired game with modern graphics. It was completed in only a week during
breaks at school. It is for download on Samsung smart watches
Go
since 2014
When I came into contact with Go, I fell immediatelly in love. The game is really fun and clever.
The Go community is excelent! Currently, I am 2 Kyu and I was 13th in European Go Youth
Championschip 2022 in U20 category.
After effects
Jun - Sep 2020
During summer, I got into video editing. I was drawn to it many times during my childhood.
I used programmes like iMovie and Premiere Pro and later I fell in love with After Effects.
Here is the craziest thing I have completed - Exploded Dancing house in Prague.
I have been also doing a lot of procedurally generated effects.
