Experience
Mireo via GPS
This is a type of navigation software, written in C++. The navigation sentences were assembled in a scripting language that I developed. I also created a matcher (the part that matches GPS location with road grid), advisor (the part that decides which advice will be given on each crossing), portable control library, and various other parts.
Mireo Fleet
Mireo Fleet is a type of fleet management software, written in C++ and C#. We also developed a later web-based version in JavaScript. I wrote drivers for particular tracking devices in C++, parts of dedicated client software in C#, and also led a team of junior web developers for the JavaScript part.
Mireo GElin
I created a showcase traffic map of Croatia, similar to Google Maps. I developed it in JavaScript and C# along with implementing my own API for remote function calling. I also developed both the server side and web application.
Universal Data Monitoring
I built a full internet-of-things solution for Vorbion. I developed the server-side in C#, the device software in C++ and Python, and the client application in C#. I also developed the server and device software.
Donkey Programming language
https://github.com/jakisa/donkeyThis is a programming language that I developed in my spare time. It is a general-purpose object-oriented scripting language but its usage has been limited so far. It is feature-complete and has all main object-oriented features implemented.
Windows Mixed Reality
I worked on the virtual reality engine infrastructure team in Microsoft Dublin's office. I mostly focused on baking (conversion from the design-time scene to the runtime scene). It was entirely developed in C++.
Latency Analyzer (LANZ)
Arista LANZ is a type of software that analyzes latency in network switches. I worked on the protocol port on the newly developed hardware version. It was written in C++ and Python. The work was performed exclusively in Linux terminal.
