Wilmar Consultancy Services
Indonesia
Business Process Analyst Intern
I played a pivotal role in two significant projects: the deployment of an integrated weighbridge station in Wilmar Indonesia's Palm Oil Mills, which boosted productivity and reduced costs, and the first live deployment of a warehouse management system. In the latter, I actively collaborated with the quality assurance team, resulting in streamlined and digitized inventory management, reduced errors, and significant time savings.
My Projects
In the "My Projects" section, you'll find a collection of projects I've worked on. These projects encompass both my academic pursuits and my contributions to interest groups and university teams, providing a comprehensive view of my experiences and achievements at NUS.
2022 - Present
Technical Advisor
Our team secured the top positions in the RoboSub 2022 and 2023 competitions, and achieved the 2nd place in the RobotX 2022 Maritime Challenge.
In my roles as Electrical Lead for RoboSub2023, I oversaw the project and served as the system integrator for the Autonomous Underwater Vehicle's (AUV) electrical subsystem. I collaborated closely with other teams to ensure a well-structured and meticulously planned timeline leading up to the competition.
My expertise extends to the design, development, and integration of in-house electrical systems for various autonomous vehicles, including AUVs, ASVs, and UAVs. I specialize in firmware and PCB design, working with chips like STM32 and ATMega to facilitate communication with a range of sensors and devices using different protocols.
In specific projects, I co-developed custom motor controllers and power monitoring boards for AUVs, designed main power distribution systems for ASVs with load balancing, and created compact power distribution boards with power isolation for UAVs. These experiences have honed my technical skills and contributed to my success in the world of robotics competitions.
2023
Embedded RC Car (RTOS)

This project was a valuable learning experience that deepened my understanding of underwater vehicle technology and its challenges.
2021
Autonomous Maze Solver Robot
NUS Module - CG1111A
Project member
With the mbot robot as a base, we developed an autonomous robot capable of navigating a maze while making turns based on the color of the maze tiles. The project involves creating a custom color and IR-distance sensors using LDR and RGB LEDs, as well as transmitter and emitter component. The main challenge is to ensure the robot moves in a straight line, for which we used PID to provide a precise closed loop feedback control.
