Potential Field Navigation for Telepresence Robots Driven by BCI

Semiautonomous navigation of a telepresence robot in an indoor environment, using its sensors (Kinect, Kinect V2, Hokuyo, and SICK laser scanners) to detect and avoid obstacles. It was necessary to filter the point cloud given by the Kinect from the noise to detect the obstacle and make the navigation efficient and effective, as time was of the essence.

The algorithm was designed to be modular to add or remove sensors to the need. The potential field navigation allows the robot to avoid the obstacle, and the semi-autonomy allows the user to give right and left commands from the keyboard. In the complete version, the user could also give the right and left command through a brain-computer interface (BCI) that translated the mental intention of the user into actual commands. The telepresence apparatus (video of the robot and network transmission) has been implemented using the GStreamer library.

Toptal React Accelerator

The Toptal React Accelerator is an exclusive learning program that educates JavaScript developers in React, Next.js, Redux, and GraphQL. This is a two-month program that consists of rigorous learning exercises and hands-on activities, a stringent evaluation process, comprehensive learning assessments, and an invoice management system. Users can track invoices, clients, and company information within this invoicing application.

Lost in the Dungeon

A card-based grinding dungeon crawler. The player's goal is to survive a series of increasingly challenging dungeons, thus being rewarded with the loot they need to get stronger and stronger. The game's core feature is an original yet simple, intuitive combat system that maintains depth and strategy. I designed an online and offline saving data system to allow users to have the saved data updated even if playing cross-platform on Android, iOS, and Steam.


A React-based app for creating notebook documents in JavaScript/React. A notebook document is a browser-based REPL containing an ordered list of input/output cells that can contain code or text (using Markdown). Underneath the interface, a notebook is a JSON document, saved locally using the ".js" extension.

Rock Galaxy

A Java-based Asteroids-like game where the users can get powerups to shoot multiple projectiles, get shields, or recharge lost energy. The game starts with big asteroids (resembling rocks) that divide when being hit, so there could be a lot of sprites on the screen at the same time. This game also has rock background music and sound effects for shooting.
