MassRoots

An Android app for the world's largest network for legal cannabis users, serving more than 250k accounts (including iOS and web) and rapidly growing. I took over the app during early stages of development when it had many bugs and succeeded in improving it from a 3.6 to 4.3 rating. I did a complete UI and functional redesign, implemented image and video editing and posting, and many other features. I also helped the back-end team improve the Parse database structure and Cloud Code functions.

Socialmist

A social app that lets the users create short videos with their favorite music from SoundCloud.

I've implemented the complete post creating flow including recording videos with custom camera, importing videos, merging, cropping and trimming them, and adding the audio stream from a SoundCloud track (the key point of the app).

Also, I've updated the UI and added some elements and behavior to give the app more of a material design UX. Major improvements were made to the image loading. Video playback on list scroll and a custom swipe-to-remove comment item were implemented. Many other optimizations and improvements were made.

*The Android/iOS apps are currently unavailable due to rebranding. Will be out soon.

FlightCar

Worked along with another Android developer to create an app for the car-sharing service FlightCar. We implemented a new UI and built a functional app from scratch. The company's technology was acquired by Mercedes-Benz before all the features were included in the app. While in the Play Store, the app provided users with the ability to reserve a car or list their car for rental, follow updates for their pickup from the airport, etc.

We365

We365 is a digital community app with user profiles, a news feed, groups, challenges, and more. The mobile app sends and receives information from the server using a REST API. I worked on front-end development and successfully implemented all requested features.

AssetWatch

A mobile client for the AssetWatch property inventory service. Users can rapidly register an inventory of their properties using a camera and bar code scanner. The communication with the server required using JSON. I implemented the complete front-end logic successfully, including some complicated specified navigation requirements.

Fridge Check

Fridge Check is an Android app that gives the user a list of recipes that can be made with the ingredients that the user has in the fridge.

I implemented the complete UI and added some interesting animations. I also adapted the basic version of the app to the new RESTful API and corrected the process of storing and manipulating with the data on the local SQLite database. Also, I integrated Facebook and allowed the users to post custom graph stories.

VPN Controller App

I developed an Android VPN controller app as part of the Datho Digital VPN plugin for XBMC (http://xbmc.org/). The controller app is invisible for the user, receives commands from the plugin back-end, passes the commands to the VPN app, and sends status changes back to the back-end.
