QuizMap

Backend developer Ruby

Integrated most of the backend API. Work included real-time functionality (websockets), and some complex calculations using geo coordinates.

Bunduru Inc.

This application is a turn-based quiz game consisting of several rounds during one game. The purpose of the game is for the players to answer questions from 10 different categories (previously uploaded on server) by placing a pin on an offline map. The winner is decided based on the distance from the correct answer (e.g., placing a pin in Germany when the answer is in fact the US will result in roughly 5,000km).

Ridicolo

Tech lead Android team

Taking photos, implemented detecting faces using the Android OS face detection API, editing photos and adding overlays over the photos.

Live preview camera app which allows the user to create funny photos by applying diversity of facial stickers. It was developed for both iOS and Android platforms, the main challenges being the implementation of facial recognition for all orientations, application of stickers when multiple faces present, processing and optimization of images and creation of custom gallery. The effects/stickers are being stored and downloaded from Parse. Ridicolo has in-app-purchases implemented.

SuperCollage

Mobile developer (Objective-C)

Integrated a new feature, an expansion of the existing collage functionality

Miinu Inc.

Super Collage is a photo app that allows combining up to 9 photos in one collage while applying various effects, borders, stickers, text, etc. The app’s target version was iOS 5.0. The most challenging steps in developing this project were managing the collage views, memory optimization, especially for iPod 4th gen due to hardware limitations, as well as applying different shaders for each collage.
