# About
> Faculty of Sciences, Novi Sad, fourth year · Novi Sad, Serbia
I study information technologies at the Faculty of Sciences in Novi Sad and I'm in my fourth year. Outside of classes I build my own apps, mostly for web and desktop.
## What I work with
I write my own projects in TypeScript and React (Next.js, Expo, Electron). At university we work in Java and Spring Boot.
## Right now
I'm working on Rezzo (0.1.0) and Košarkaški iks-oks (0.19.0).
## Other
I follow football and basketball, I'm curious about AI and I like to travel.

# Rezzo
> A desktop app for cutting vertical clips out of podcasts and talk shows.
I post podcast clips on social media, and the work is the same every time: find an interesting moment, crop a wide shot down to 9:16, keep whoever is talking in frame, add captions. The apps that handle this well either stamp a watermark on the video or put the useful parts behind a monthly subscription. Rezzo does the same job for free, and every feature is in the free version because there is no other version. It's made for Serbian shows first, since that's what I work with.

# Košarkaški iks-oks
> Tic-tac-toe with EuroLeague players.
The board is 3×3 and every square has two criteria (club, nationality, position, title, era). To take a square you type in a player who meets both. You play with a friend through a link or on one device, with a timer and rematches. There is also a daily board, the same for everyone, that you solve on your own. I made the promo video in Remotion, and the match and colours in it come from the app itself.

# EvidLab
> Tracking chemicals and lab supplies.
A team project from university. We built it for a department at the Faculty of Sciences, following Scrum practices, to replace the records they kept in Excel. In the spreadsheet names were duplicated, nobody could tell how much of anything was really in stock, expiry dates were missed, and anyone could change the numbers without leaving a trace. That also made it hard to plan what to order. The app has an AI assistant and voice input too, but it works without them.
