Dynamic Data Pipelining System

CPP, MPI, OpenMP

• Built an efficient data pipelining system that can dynamically create/scale data pipelines and process data parallelly based on predefined data/task dependencies.

• Used the parallel computing techniques such as MPI and OpenMP to optimize the performance in terms of strong and weak scaling.

High-dimensional Computing SoC Design

RISC-V, Chisel, Verilog, C, Python

• Designed a high-dimensional processing unit to perform AI-tasks (e.g., classification, regression, etc.) and integrated with a RISC-V core.

• Created custom ISA that runs on RISC-V and wrote embedded software that controls the acceleator.

• Used a python script for code generation of large scale AI application such as language recognition.

Reading Glove

Arduino, C

• Designed a glove with an Arduino and a camera mounted to the palm such that it can be hovered over text to have the text read out to them via a speaker

• Used BLE to configure the camera, IMU to detect the movement and orientation, and UART to transmit images

• Finite state machine runs on the Arduino to control the reading glove logic.

Cooking Sawyer

ROS, Python, OpenCV

• Identified ingredients at random locations on the table using computer vision (colour thresholding).

• Used AR tags to calculate the relative coordinates between the ingredents, gripper location, and preperation area.

• Followed a desired recipe to assemble a customized burger using motion planning.

Spam Detection System over multi-FPGA Network

Verilog, C

• Designed both the hardware and software system and utilized 3 FPGAs, communicating over the network through the TCP/IP protocol.

• Implemented the spam detection probabilistics model and designed the inference logic on FPGA.

Distributed Systems CRDT Library Design

C++

• Designed a CRDT library with functional and performance benchmark to achieve strong eventual consistency and low merge latency over the network.

• Created a Trello-like project management application using the CRDT library to showcase the advantages of a decentralized distributed system approach instead of a server-based approach.

TinyML Magic Wand Project

Arduino, TensorFlow

• Implemented keyword spotting and gesture recognition and created an end-to-end pipeline from data collection/pre-processing to model training, converting model to TF Lite/Micro for deployment on Arduino

KUKA Robotic Manipulator

MATLAB

• Drawing with forward kinematics

• Motion planning with obstacle avoidance

X-ray Diagnosis on Bacterial and Viral Pneumonia

PyTorch

• Using convolutional neural network and transfer learning to create multiclass classification

TV Schedule Search

HTML, PHP, CSS

• Make a website that searches for TV series schedule of the current season and weekly episodes

Map Application Software Design

C++, OpenStreetMap API

• Created higher-level API and develop graphics interface for the Geographic Information System

• Found the fastest path and the most efficient way for courier companies to deliver packages

• Applied Dijkstra and A* algorithm, local search, and 3-opt

Flappy Bird Game Hardware Design

C, ARM Assembly

• Developed bare metal code on FPGA and ARM core using VGA display and PS2 controller

Piano Tile Game Hardware Design

Verilog

• Applied the knowledge of VGA adapter, audio controller, and Finite State Machine on Intel FPGA
