2024-now System Analyst @ PSA
Excited for the first step of corporate life as a fresh graduate!
About Me
I have recently graduated from the National University of Singapore (NUS) with a Bachelor of Science in Data Science and Analytics. I also took a minor in Computer Science, which I believe will be a good supplement for my data science journey!
Experience
A list of my working experiences are included below. Click on the images to find more details!
2023 Research Intern @ A*STAR
I kept exploring different fields of internships and am now doing some research on multi-robot search algorithms using simulatenous localization and mapping (SLAM) and guaranteed search with spanning trees (GSST). This is also my final year internship!
2022 Testing Engineer Intern @ TikTok
I received the offer to become a testing engineer intern at TikTok during the whole summer of 2022! In this role, I perform quality assurance on features and platforms related to TikTok, making sure customers are able to use it functionally well.
2021-2024 CS1010S Teaching Assistant
I am currently a teaching assistant (ex-head) for the Programming Methodology (CS1010S) course, which will be in Python. Aside from teaching, I also contributed on developing the autograder system in the course website. Feel free to look at the module details here.
2022-2024 CS2040 Teaching Assistant
I am also a teaching assistant for the Data Structure and Algorithms (CS2040) course, which will be in Java. I touch more on the concepts of how the common algorithms work and break it down into a more understandable explanation. Feel free to look at the module details here.
2022 DSA2101 Teaching Assistant
Three modules the charm? I also teach at the Data Visualisation (DSA2101) course, mainly on discussing tutorial solutions and grading assignments, which uses R as the programming language. Feel free to look at the module details here.
2021DSA Tutor @ Wardaya College
I taught an 11-week course called CS101 about data structures and algorithms in Python. I also made an assignment set weekly for my students to practice about what is taught for the week.
2020DS Instructor @ EKTIZO Coding
I decided to become an instructor for a 6-week data science workshop. We managed to cover topics such as Pandas, Matplotlib, and NumPy.
Projects
Projects that I've been working on, including those in progress. These projects are currently related to my activities in NUS. Click on the images to find more details!
DSA4212
A trio of projects within the module DSA4212: Optimisation for Large-Scale Data-Driven Inference, a module that I personally really enjoyed.
- Image classification using PyTorch, Tensorflow, and JAX to make a neural network from scratch
- Recommendation system for animes using various approaches including the matrix factor model and Singular Value Decomposition (SVD)
- Solving a Travelling Salesperson Problem (TSP) instance using various approaches, including the ant colony optimization, the k-opt strategy, and simulated annealing
autokattis
An API wrapper for the Kattis website that contains past competitive programming problems using web scraping tools. It automates various data collection processes and visualizes it at will. It started back in May 2023 and is now installable as a Python package.
Unsquaredle: Squaredle Solver
Using Selenium and bitmask backtracking, you can automate the Squaredle word search game and find as many bonus words as you can.
Pancake: Waffle Solver
Using Selenium and the A* search algorithm, you can also automate the Waffle word game with 5 moves remaining. With the same code you can also solve Wordle!
Unredactle: Redactle Solver
A simple web scraping and RegEx tool to solve the Redactle game that aims to guess the Wikipedia page title based on its redacted content.
Predicting HDB Resale Prices
As part of the ST4248: Statistical Learning II project, a team of four people including myself trained various machine learning models to predict HDB flat resale prices and explore how each of these models work. The full report can be seen on this website.
Stashy
A simple chatbot using Java as the individual project component of the module CS2103: Software Engineering. The GUI was created using JavaFX.
FypManager
A dashboard tool to manage students' final year projects (FYP) as a modification from a simple address book using Java. The project was done by a team of six including me and was also the team project component of the module CS2103: Software Engineering. The GUI was created using JavaFX as well.
Legwork: Privacy-aware movement tracking
Using R-CNN, one can predict the supermarket visitor flow using ESP32-CAM cameras that capture just the lower limb to avoid capturing identifiable features of individuals. This project of eight members was part of the module DSA3101: Data Science in Practice.
Rune Compiler Bot
To assist CS1010S students on their first few assignments involving "runes", I made a Telegram bot that generates the images of the runes automatically to compare against their workings conveniently. As a fun side quest, I also added more runes that can be found within this Telegram bot.
Twemoji
This was a machine learning project me and my friends did for the module CS3244: Machine Learning and revolves around natural language processing. The aim was to predict an emoji best associated with a given Twitter post, which was extracted using Twitter's API.
BATCH Project 2021 Telegram Bot
A bot for University Scholars Programme's (USP) orientation camp, implemented in Python and JSON.
Puzzle Hunt Telegram Bot
A puzzle bot for Mathematics and Statistics Orientation Camp (MSOC) 2021, also implemented in Python and JSON.
Activities
Studying hard isn't enough for me in NUS. These activities are important and actually became my self-enrichment, too! Click on the images to find more details!
2021-2024 Peer Mentor @ Pioneer House
I'm a Peer Mentor in my current NUS hostel, Pioneer House (PH). Being a student leader trains my leadership and communication skills, and therefore I'm having fun with the position!
Here are the list of Telegram bots I have incorporated in my mentoring events so far:- PCT 5 Kirisus Bot: A Telegram bot for my residential block for AY2023/2024, specialised in making mahjong invites and giving useful links at will.
- PCT 9 Vulpes Bot: A Telegram bot for my residential block for AY2022/2023, specialised in sending birthdays and echoing only myself.
- Dinner and Python: In 2022, I gave a workshop on how to create a Telegram bot using Python. The two-hour session used Google Colab and was successfully conducted with around 20 residents.
2020-2021 Programmes Subcommittee + OGL @ Math & Stats Orientation Camp 2021
Besides planning on the games and the events for the camp itself, I decided to implement a Telegram bot for one of the games and simultaneously led
an orientation group!
Really wished the camp was longer 😊
2020-2021 Tech Subcommittee @ NUS Angklung Ensemble
First time trying to code something serious outside Python, which is JavaScript and Svelte. Also my first time creating a custom audio player.
2020 Puzzle Subcommittee Member @ NUS Mathematics Society
I signed up as one of the proofreaders and puzzle editors for the MathSoc weekly puzzle. You can check it out in their Instagram posts here!
