Software Developer in Belgrade, Serbia

I worked on the whole stack, but mostly on the back end dealing with infrastructure design on AWS, data security, REST APIs, and operator tools. On the front end, I wrote a lot of Angular and React code for many client apps and apps for internal use.

This was a startup that had an idea to promote properties directly to clients via direct video calls using a web browser and an internet connection, without the client having to install Skype or sign in to our website. My job was to test if an Android device (at the time) could render usable 720p video stream. I used GStreamer, WebRTC, and other technologies/libraries successfully.

I started working on the existing system for employee management, and later, I led the way of switching from jQuery to a more professional ExtJS SDK. I implemented the back end in C# and did the core development of the front end in ExtJS. The system consisted of an RFID reader that sent ID card data to HTTP Server, that stored them in DB, and ExtJS WebApp that offered UX similar to a Windows desktop.

I developed this system from scratch in C#. The system consisted of RTSP Server that runs as a Windows service and Windows Forms desktop app that rendered up to 64 RTP streams. I also wrote all the required DirectShow filters in C++.

At GreenMoney, I worked as a freelance developer with a couple of other developers. My tasks were mostly related to fixing some issues on the C# back end and fixing issues with Microsoft SQL database. Some of the bigger tasks I worked on were implementing the Android app for the website, implementing new features in the administrative part of the website, and database design and management.

I worked on developing an Android application template to easily create Android applications for new clients of the platform. The Android app was a simple "web wrapper" that rendered the website and intercepted actions like sign in, sign out, subscribe, and replaced HTML views of the website with native Android layout.
