A React-native based mobile application, Vigo is a delivery company that assigns the internal couriers to other companies per delivery based, created a context for socket connections of the application using Socket.IO and React Hooks.

I created a performant map structure for displaying points over the map.

Dockerify

https://github.com/ctur/dockerify
An open-source Docker-based development environment project contains some of the basic tools that you need for Node.js development. With this, a user can easily connect and start developing using VS Code Remote (container-like extensions).

DroidAR

DroidAR is a location-based augmented reality game that was created as an independent side project using Unity Game Engine.

I designed 3D world objects with a character that replicates the user's real-world movement gathered over GPS. I used several APIs like Google Places to create the game world.
