I am a Zagreb-based developer who likes building real, finished things across very different stacks. Over a few intense months I shipped a flagship offline-first desktop app, a self-hosted Discord-style comms platform I run end-to-end, two game-jam games (Unity and Godot), a university capstone game in Java, a full-stack finance app with a team, and multiplayer mods for Steam games.
I move comfortably between low-level systems work (Rust + Tauri, on-device speech-to-text), game engines (Unity/C#, Godot/GDScript), full-stack web (Angular + .NET, Astro), and self-hosting my own infrastructure (Docker, LiveKit/WebRTC, TrueNAS). I plan with the BMAD agile method and care about honest, shippable software over hype.
Beyond code, I'm also a content creator — comfortable with video editing and streaming (Premiere Pro, OBS, Paint.NET) and the everyday office and project tools (Microsoft Office, Jira, Azure DevOps).
I am a third-year Software Engineering student at Algebra University College in Zagreb, and I am open to internships, junior roles, and collaborations. If any of this looks interesting, my inbox is open.
Razvojni sam programer iz Zagreba koji voli graditi stvarne, dovršene stvari kroz vrlo različite tehnologije. Kroz nekoliko intenzivnih mjeseci isporučio sam glavnu offline-first desktop aplikaciju, self-hosted platformu za komunikaciju u stilu Discorda koju sam vodim od početka do kraja, dvije game-jam igre (Unity i Godot), studentski završni rad u Javi, full-stack financijsku aplikaciju s timom i multiplayer modove za Steam igre.
Jednako se snalazim u sistemskom radu niske razine (Rust + Tauri, govor-u-tekst na uređaju), game engine-ima (Unity/C#, Godot/GDScript), full-stack webu (Angular + .NET, Astro) i samostalnom hostanju vlastite infrastrukture (Docker, LiveKit/WebRTC, TrueNAS). Planiram BMAD agilnom metodom i cijenim pošten, isporučiv softver umjesto pompe.
Osim koda, bavim se i stvaranjem sadržaja — vješt sam u montaži videa i streamanju (Premiere Pro, OBS, Paint.NET) te svakodnevnim uredskim i projektnim alatima (Microsoft Office, Jira, Azure DevOps).
Student sam treće godine Programskog inženjerstva na Visokom učilištu Algebra u Zagrebu i otvoren sam za prakse, junior pozicije i suradnje. Ako vam je nešto od ovoga zanimljivo, moj inbox je otvoren.
