I have two years of corporate experience in (i) research and economic analysis, (ii) project management, (iii) trade negotiations and (iv) strategic planning.
In my research portfolio, I analyzed trade flows and sectoral economic data to produce policy insights and actionable recommendations.
I also saw through the development and deployment of a Customer Relationship Management (CRM) system for MTI. As the project manager on the business end, I managed the collaboration process with end-users and MTI management to ensure that the system met the needs of business users and provided a streamlined user experience.
I was part of the team which renegotiated the Singapore-Australia Free Trade Agreement and the Korea-Singapore Free Trade Agreement (KSFTA). I also provided support to MTI’s senior management on MTI’s organizational and strategic planning.

My talks (so far)
- How to build a simple web application on Node, Express and Leaflet.js (slides)
Learning Ninja
The app that hopes to disrupt Singapore’s tuition industry
The Big Idea
The app hopes to:
- make learning math fun and addictive through gamification
- maximise learning by engaging both the left brain (logic and words) and the right brain (imagination and visuals)
- provide unlimited quests and questions on topics covered by PSLE, ‘O’ and ‘N levels’
- provide immediate feedback on what the user knows/doesn’t know
- encourage active learning through guided hints
- reduce teachers’ workload (no marking needed!)
The Stack
- Built with: MongoDB, Express, Angular 1, Node
- Demo: https://learning-ninja.herokuapp.com
- Code (client): https://github.com/davified/tutor-client
- Code (server): https://github.com/davified/tutor-api
Readr
Say goodbye to internet junk
The Idea
- Readr is an app that allows people to share and read awesome articles, without the ads.
- By just pasting the url link, the user can read the article in a clean interface, and the app will automatically generate summaries (TL;DRs) and topic tags.
The Stack:
- Built with: MongoDB, Express, Node, JQuery
- Demo: https://flight846.github.io/readr-client
- Code (client): https://github.com/flight846/readr-client
- Code (server): https://github.com/davified/readr
Carparks-SG
The Idea
- Carparks-SG provides real-time data (updated every minute) on carpark availability in the CBD area. The data is kindly made available by LTA Data Mall.
The Stack
- Built with: Node, Express and Leaflet.js
- Demo: https://carparks-sg.herokuapp.com
- Code: https://github.com/davified/project-3a-clean
Snoke
The Idea
- Recreating the classic 3310 game with Javascript and a twist
The Stack
- Built with: Vanilla Javascript
- Demo: https://davified.github.io/snake-game
- Code: https://www.github.com/davified/snake-game
Volunteer now
The Idea
- The app was designed with one goal in mind: to make volunteering opportunities more accessible to everyone.
- It allows organizations to upload volunteering needs/opportunities, and it allows users to be aware of volunteering opportunities that match their skills.
The Stack
- Built with: Ruby on Rails (Rails 5)
- Demo: https://volunteer-now.herokuapp.com
- Code: https://github.com/davified/volunteer_app
Panama Papers
The Idea
- Practicing python with the Panama Papers dataset
- Key findings:
- The top 5 source countries of companies found in the Panama Papers are: British Virgin Islands, Hong Kong, Switzerland, “Not Identified” and Panama. I guess the lawyers and accountants have learnt to hide their trail well. Apart from the clear suspects (BVI, Panama), there is a big chunk which is “Not Identified” - and this makes it quite hard to conclusively identify tax havens.
- Even though Singapore is often touted as a possible tax haven, the figures show that the degree to which it houses companies related to the Panama Papers is much lesser as compared to Hong Kong, Switzerland, British Virgin islands. That said, as a source country, it is ranked 15th (5,867 companies), right after the United States (6,254 companies). As a jurisdiction (destination country), it is ranked 11th (668 companies), right after Nevada (1,260 companies) and Hong Kong (1,331).
