MusicBox is a music streaming service focused on cafes, restaurants, hotels, and similar venues where music is an important part of the experience.

For MusicBox, I developed a custom MP3 streaming server in Go—capable of delivering thousands of different music channels on modest hardware. I also developed the Django application that users can use to control the service which communicates with the streaming server using Redis. I automated the deployment of the entire system using Ansible.

On the client-side, I built a Raspberry Pi-based media player that acts as a client for the service with adaptive buffering, offline play, and other important features.

Web Whiteboard is a real-time shared whiteboard service (Google Docs for whiteboards), used by over 200,000 users worldwide each month, from kids in kindergarten to Ivy League schools and Fortune 500 board rooms.

I developed the initial version using Node.js, Socket.io (WebSockets) and MongoDB. I continued my engagement with the project in the CTO role.

I designed and developed a custom digital signage solution that utilized Python-based content players (capable of full or boxed-screen playback of multiple types of content—including 2x HD streams on Nvidia ION hardware), Windows-based content and player management application (C#/WinForms), a RESTful API, and content server.

Naslovnica ("Frontpage") was the largest local news aggregator in Croatia that fetched news articles from dozens of media outlets and presented (the excerpts) in a user-friendly and easy-to-read way.

I developed the site using Python for the back-end and PHP for the front-end and devised an article deduplication algorithm that collated articles from different sites that talked about the same thing.

Ultimately I sold the site to Styria (the leading regional media group).

A Django application that provides middleware for inspecting and reporting SQL queries executed for each web request.

I built it to help me identify the sub-optimal SQL queries we sometimes generated by mistake or omission. Since open sourcing it, it has become quite popular and widely used.

A lightweight set of tools for implementing JSON-based RESTful APIs in Django. It helps with writing APIs that loosely follow the RESTful paradigm without forcing you to do so and without imposing a full-blown REST framework.

Although these days, I mostly use a Django REST Framework since it's become the de-facto standard way of doing REST in Django, I still maintain (and have uses for and users of) Django-Restless.

A simple educational operating system built on top of the L4 microkernel. I designed and implemented it as part of my graduation thesis.

For the OS, I implemented the memory, namespace, capabilities, disk, filesystem, and console services as well as an ELF loader, and ported a few simple open source tools (tiny basic and scheme interpreters).

I co-founded a small community-oriented web developer conference in 2012. The conference grew to be the largest of its kind in the region, visited by over 600 people over two days each year.
