This is how I started programming. First in Pascal, then in C++. I've enrolled in competitions (HSIN.hr and Infokup.hr) and achieved the first place in regional competitions a couple of times. Besides problems that can be found on hsin.hr and infokup.hr, I've also done a fair share of problem solving on spoj.com. Here's my profile.

This was my first encounter with object oriented programming. I found a server emulator for an MMORPG game I had been playing for a long time, written in C#. Someone wrote it and made it open source so anyone could make their own private server. When you create a character in the game you can choose whether it's European or Chinese. What I did is modified the code so that Europeans and the Chinese were able to PvP (fight against each other) all the time, wherever they were, along with a some other modifications.

During primary school, my school partricipated in an international mathematics competition - "World Math's Day". The goal was to solve as many equations as you could within a minute. There were four levels. First one was addition, second was addition and subtraction, and so on. Whoever solved the most equations overall was the winner.

I was bored with the repetitive task, so I made a bot that solved equations for me. Everything happened inside a browser, and using Flash. I didn't know how to read the given equation from memory so I built my own OCR in C# which scanned the screen, cropped the part where the equation was and detected the characters, interpreted the equation and the bot typed in the solution. Here's a video on how it worked in practice. My intention wasn't to cheat, but to prove a concept, so I notified the WMD team and they gave me an award "Honorary programmer".

Discovered and reported some severe bugs in multiple systems. Included some SQL injection, brute forcing with a program written in C#, using Selenium framework.

Written in Node.js, like a terminal inside a web browser, messages encrypted with SHA-256, with features like taking screenshot and automatically uploading it to the chat, floating embed Youtube videos by just pasting the link, and some other fun features, like memes flashing, l33t speak and others.

My first large, and second biggest project, written in Node.js and a bit of C++ and Bash. People could buy points via SMS and use the points to create instances of Minecraft servers. Everything was automated, iptables was used to tunnel traffic from main server (which was DDOS protected) to nodes (with load balancing) which ran the server instances. Here's a couple of videos, made by kids, of how to create an InstaMc Server: 1, 2, 3, 4. Most of the source code got lost.

A Node.js project. Everything that student dorm staff had on paper, I put it inside a web application that quickly grew very large. Currently in use in three student dorms, the system with over 20,000 lines of code features an 11-level user permission system. Two card readers are a part of the project, one at the entrance to the dorm, and the other in the kitchen. Whenever a student or staff member enters or leaves the dorm or eats in the kitchen, they use their RFID card to identify themselves. So the system logs movement, working time records, and generates statistics (with colorful graphs). A ground plan is also available which shows in which room which student is.

System administration of Windows computers at Faculty of Economics, which, frankly, could have been fully automated but, for some reason, wasn't. Also did system administration in one student dorm.

GAMESS GUI developed for biotechnology and chemistry students, written in Node.js. Download here.

I was given a task to retrieve the sensor data from the refrigerated container and send it to the server, all with "Skywave" device running embedded Windows by Orbcomm. With no documentation on the proctocol used, I've found an app that does a similar thing, which was luckily written in .NET, so i reverse engineered it, and implemented the protocol in Lua code that then got uploaded to the Skywave.

This web app has been created for Port of Rijeka per request, as a part of an EU project. It's purpose is to place containters on wagons more efficiently, i.e. to save space and money. You can try it out here with credentials admin:admin. While you're at it, try clicking on a container when viewing layout.

A recent work. I've only done a part of work on this one (backend), but enough to have learned how Wordpress works in detail.

A web application with admin panel (based on a fork of eDorm), and a front page (for the kiosk device). Make sure you have a 1080p fullscreen or higher resolution when visiting the page.

Developed a web application that implemented Quine-McCluskey algorithm, just for fun.

I was helping in the family business - renting apartments. This included communication with guests, maintenance (small repairs) and cleaning.
