Antonio-Radu Varga

I created, designed, and launched a personal project for integrating the powerful audio interfaces from Universal Audio with MIDI. This eases the control of the various parameters, including volume, mute, sends, effects, and more, which was previously only possible using the mouse.

I continued the development of an existing web app used by home builders to view and customize floor plans for their houses. My responsibilities included adding new graphic features for editing the SVG plan, reorganizing the UI and back-end elements, simplifying the deployment process, fixing older issues, and refactoring old code.

An augmented-reality app for 3D sound tours around the city. The mobile app was implemented in Ionic and Angular with a back end in Clojure and a web dashboard with Google Maps for adding walks.

I designed and implemented a web application that heavily relies on SVG to create various financial graphs from imported Excel files. The designs were created pixel-perfect for printing from Illustrator files.

I designed and developed a complex web application for organizing economic calculations of airplane transactions. I created the UI as a SPA in ClojureScript, the back end in Clojure, and separated Clojure workers for complex tasks. The production was managed in Heroku.

I improved and heavily refactored an already-started VPN app in Android. That involved some complex background operations that also used the Android NDK (C code).

An Android app for a security device of a startup in Berlin. I perfected my UI implementing skills, increased my Android technologies and libraries knowledge, and gained experience pushing code in a team and constant code reviewing.

I implemented an Android app that auto applies proxy settings. I investigated the details of the Android permission system, also going into the source code. That improved my understanding of the new Android 6 (Marshmellow).

An Android fitness app created in addition to an already existing iOS app. I implemented optimizations to show images and video streams as efficiently as possible. Also, I created a complex set of Android fragments to reuse views and subviews.

A customer service web and mobile chat application. I developed the webserver in Clojure, then the mobile-friendly web application in HTML5, CSS, and JavaScript. Finally, I created the Android and iOS apps as web apps.

An intelligent home-automation system that integrates hardware devices from the user's home. I worked with different home electronics, such as TVs, audio amplifiers, lighting, temperature control, and more, communicating via protocols like TCP/IP, RS232, and Z-Wave. Technologies include Android, Delphi, JavaScript, and PHP.

This is a personal project which consists of a guitar tablature player for the web. I created everything for this app, except for the UI design. The player is implemented in ActionScript, the webpage in HTML5/JavaScript and the tablatures for different songs are transcribed by myself.

I implemented a standalone offline music player for the Raspberry Pi in Python. The music was loaded via a USB stick, and a smart playlist would start automatically when it was plugged in.

I performed full-stack development for a radio app. The server was implemented in Node.js for handling thousands of simultaneous WebSocket connections, and one web service was written in PHP with the use of an Apache web server.

The client's applications include a native Android app and a browser app that plays an audio stream, as well as a chat function, and downloads images and text through our API.

Analytics data was recorded and visualization was implemented into the web client.

A mobile-friendly presentation website for my musical and software projects. It was hosted on GitHub Pages using Jekyll.
