The project is about auto-beautifying videos from your Android camera. It consists of a client and a server (pretty obvious). The server was developed on the customer’s side whereas we developed the Android client. No specific custom technologies were used, but we used many different parts of Android SDK (probably, the one we did not use was a database).

My client wanted me to improve the existing live-streaming Android app by fixing some bugs and adding new features.

The work included working with WebSockets, using 3rd-party library to view RTMP streams, adding a functionality that required an integration with new server APIs, and changing the app's UI to implement Material Design.

My client and end-users were satisfied with the app and the app's rating has increased since I worked on the project.

My client wanted an Android app to enable users to follow their favorite public figures on different social media networks in one place. So instead of switching back and forth between Facebook, Twitter, and Instagram you can have a mixed timeline of everything.

I implemented the app applying Material Design guidelines and the latest API guides suggestions. I integrated Facebook, Twitter, and Instagram APIs in a way that allowed me to manage them uniformly. The project required managing background tasks and using a SQLite database.

It was a really nice experience.

A simple Android application that I was tasked to create for a client on another freelance platform. It lists the user's phone contacts and lets the user assign a location to any of them.

The target product was a kind of smart-card emulator. The idea is to use your mobile device as a security token (for example, to sign-in to Windows). Your device (BlackBerry, WinPhone, or Android) communicated with a so-called middle-layer via Bluetooth—exchanging some crypto-stuff such as keys, certificates, and more. The middle-layer in turn can be used by an end-user’s application to provide necessary security features.

My role was to develop the Blackberry client.

An Android SDK for creating mesh networks via BLE. It enabled a device to send HTTP requests even if it was not currently connected to the internet directly. In such cases, the request would be forwarded via mesh to a device connected to the internet.

I was an Android developer on the project and implemented device disappearance propagation, internet connectivity detection, and propagation. I also stabilized the project by adding thread-safety and improving BLE communication synchronization.
