About me

I am a Computer Engineer by trade. I enjoy solving complex problems and I can't stop learning new things! I am extremely interested in Internet of Things (IoT), Artificial Intelligence (AI)/Machine Learning (ML) and am a huge fan of automating as many tasks as possible, making life just that much more fancier and easier! I have also done a couple of web-dev projects and am comfortable with several frameworks and libraries. I am keen on learning more about Human-Computer Interactions and continuously upgrading myself in the area of AI/Machine Learning and IoT.

LaserTag++

Python | C | MQTT | Jupyter Notebook | Pandas

With a budget of $250, we came up with a laser tag game with gesture detection (for reload, grenade, shield and logout actions). We produced an immersive game experience that fuses both the modern First Person Shooter (FPS) games and laser tag sport. Through the use of sensory and Augmented Reality (AR) technologies, players can experience a shooting game in a simulated environment. Players will be able to interact with the environment and perform actions such as reloading, throwing grenades and raising shields, which will be visualized on a mobile device that is mounted on the gun. For a more realistic simulation, players will receive vibration and visual feedback from their vest and gun. A gameplay demo can be found here.

Wireless Neighbour Discovery

ContikiOS | C

Implemented a quorum based neighbour discovery protocol, making use of acknowledgements and packet filtering to send light sensor readings to selected nodes via broadcast messages if they were detected for a set period of time and within a certain range. A high level technical overview can be found here.

Neural Network Hardware Accelerator

Verilog | C

Accelerated a neural network model using an FPGA, by parallelizing matrix computations. A high level technical overview can be found here.
BeyondVision

Python | C | MQTT | Jupyter Notebook | Pandas | Flask | HTML

BeyondVision is a proof of concept/prototype of a smart walking cane to assist the visually impaired. The walking cane sounds off when an individual is too close to other people/objects, detects fires nearby or detects when the user falls (using an IMU sensor and ML algorithm). Subsequently the location detail is sent to the next-of-kin alongside the situation (fall/panic button pressed/fire) via a telegram message. A high level technical overview can be found here.

Knewbie

Python | Flask | HTML | CSS | JavaScript

Hosted by NUS & suppoted by the likes of Google & Paypal, this was undertaken as a summer project. The platform employs machine learning to provide tailored educational content to PSLE Math students, ensuring they learn optimally. Out of 383 projects, Knewbie was 1 of 6 projects to be featured on the various social media accounts.

FPGA Development

Verilog

Used Verilog to develop an entertainment unit for a FPGA project. Features include, a tetris game, a ping-pong game as well as using a microphone to read volume and visualize volume readings in the form of waves and bars. It also contained a home screen and a lock screen which can only be unlocked when a correct sequence of buttons were pressed at the right ambient volume.

Carpark Availability Recommender

Python | Pandas

The recommendation system targets users aiming to plan their trips early. Users will be required to provide their destination and estimated time of arrival (in terms of hours from now capped at 24 hours) and the system will provide them with the best available parking option based on distance from their destination and parking availability. A high level technical overview can be found here.
