[Final Report] [Presentation Slides]
DBS Bank Ltd is a Singapore multinational banking and financial services corporation that was established on 16 July 1968 and is headquartered in Marina Bay, Singapore. Over the years, DBS has continued to innovate and adapt to technological disruption, enabling her to be recognised as the World’s Best Digital Bank. Since its establishment, DBS has expanded into 18 markets across the globe with over 280 branches (DBS, 2018). This includes 6 priority markets in Asia, namely Singapore, Hong Kong, China, India, Indonesia and Taiwan.
I was attached to the Technology Service department under the Technology and Operations business function. My team was responsible for the development and support for CUS related application development work, which is critical especially during the Covid-19 pandemic, as most employees depend on collaborative services to work with one another while working from home.
During my internship, the team was working on a web application to monitor the availability and performance of CUS such as Microsoft OneDrive and SharePoint, as well as mobile services such as BlackBerry Work. The application relies on the use of bots to test variables such as login time, upload/download speed to determine the availability and performance of the services. In addition, the web application allows different departments to keep track of relevant metrics such as the breakdown of the number of company issued mobile devices by country and application utilisation percentage by displaying the data in the form of graphs and charts.
Major Tasks:
- Created RESTful API using Node.js for bots developed by colleagues to upload performance data to the MongoDB database. API also allows data to be downloaded to be displayed using Highcharts on the React front-end
- Created RESTful API using Node.js for upload ad download of metrics data to MongoDB database
- Test APIs extensively using Postman
- Integrate APIs with React front-end using axios
- Integrate TinyMCE WYSIWYG HTML editor onto React front-end for users to directly alter HTML content on front-end
- Presented completed work to colleague taking over the project, ensuring a proper handover process at the end of my internship
Minor Tasks:
- Port data from old to new MongoDB database
- Worked together with fellow intern to create API documentation
- Integrated SonarQube (static analysis to detect bugs and vulnerabilities) and NexusIQ (detect security vulnerabilities) into Jenkins pipelines via groovy script

Full-Stack Web Developer Intern
Clickr Media is an Internet marketing consultancy. I interned in the tech department and was primarily involved in web development. On top of implementing client specifications, I was heavily involved in an individual internal project. I started part-time in October and November and transitioned to full-time during the winter break.
My task was to create a project and employee work hours management site to help project managers keep track of deadlines and hours expended for the projects under their charge. Additionally, project managers are also able to retrieve work hours clocked by each employee to ensure that all work is accounted for. They are also able to export project and work hours reports in the form of an excel sheet for easy dissemination. Finally, the site also sends out a task reminder to project managers' emails whenever a project is due in a few days.
My project has significantly improved internal processes of Clickr by automating the tracking process. Previously, many of these processes were handled via Google Sheets and there was a lack of automated reminders and updates. I have also incorporated the jquery plugin, DataTables, for fast retrieval and sorting of information.
Major Tasks:
- Created project and employee work hours management site using HTML, CSS, JavaScript, PHP, SQL & WordPress to improve project billing in the company amounting to thousands of dollars in revenue
- Implemented DBS supplier portal using HTML, CSS & JavaScript based on AdobeXD design provided by DBS, paying close attention to the look and feel of the website
- Created a Developer Guide and briefed person taking over the project, ensuring a proper handover process at the end of my internship
Minor Tasks:
- Website maintenance for clients such as DBS, DHL, Blackmores, K W Ong Breast Clinic and more
- Data migration for DBS media site

Amazon Clone
[Project Page] [GitHub]
Amazon Clone is a web application developed using React, with a Google Firebase back-end. This project was developed throughout the winter break in my third year of studies as a computer science undergraduate.
The purpose of this project is to explore full-stack web development, which we are not exposed to during the course of our studies. Visit the project page for an overview of the features implemented in Amazon Clone!
Technologies used: React, Firebase (authentication, functions and cloud firestore)
Static Program Analyzer (SPA)
To answer program queries, the SPA must first analyze a source program and extract relevant program design entities, abstractions, Abstract Syntax Tree (AST), program Control Flow Graph (CFG) that are stored in a Program Knowledge Base (PKB). Secondly, the SPA must provide the user with means to ask questions about programs. These questions are written in a formal Program Query Language (PQL). SPA processes the PQL queries based on the information found in the PKB and returns the results to the user. The SPA was developed alongside 5 other computer science students from the National University of Singapore as part of a requirement for our software engineering module, CS3203.
Major Contributions:
- Implemented the following subcomponents of the Query Processor:
- QueryValidator - validates the semantic validity of the QueryParseResult (from parsing a query string) before the QueryBuilder uses the QueryParseResult to build a Query
- Query - internal representation of a user query that is easy to use for evaluation
- QueryBuilder - builds a Query using the QueryParseResult
- Served as the team’s Test IC, performing extensive unit, integration and system testing
Technologies used: C++
JP Morgan 2020 Code for Good Hackathon
[Project Page] [Product Demo Slides] [Product Demo Video] [GitHub]
I participated in the 2020 APAC Code for Good virtual hackathon organised by J.P. Morgan, where teams were challenged to develop innovative technology solutions in 24 hours for nonprofit organisations under the guidance of JP Morgan's very own technological experts.
My team took on the challenge statement proposed by New Hope Community Services, which is an organisation that assists displaced individuals in their application for subsidized housing from HDB.
Our solution was to develop a progressive web app which provides a centralised and collaborative platform for easy updating of records and convenient tracking of client progress. To increase the matching accuracy between clients and potential flatmates, we employed machine learning techniques (K Nearest Neighbours algorithm) to compare the similarity across the different preferences and return the top 3 recommendations.
We emerged among the top 4 teams in our category. It was a really enjoyable experience collaborating closely with people I had just met for the first time.
Technologies used: Gatsby (React), Firebase, Figma

Extracurriculars
Vice-Captain
During my first year as a freshman in NUS, I won first place in the NYSI and SUNIG competitions, and first runner-up in NUS Open. I also had the opportunity to represent NUS overseas in the Panasonic 20th Asia Pacific Water Polo Tournament held in Hong Kong, where we faced national and state teams from Australia, Philippines and China.
My commitment to the team, coupled with my playing ability, resulted in my appointment as vice-captain in my sophomore year. As vice-captain, I am responsible for the management of team morale and ensuring a high quality of training. Moreover, I am involved in the organising of competitions and hosting of foreign teams. Recently, we hosted The Hong Kong Polytechnic University (PolyU), and I liased with the NTU team to organise a tournament, providing a good training experience for the PolyU team.
During my term as vice-captain, I have been successful in leading the team to a first place finish in the NYSI and SUNIG competitions. My captain and I aimed to have a clean sweep of first positions in every tournament the team plays in during our term as leaders.
