Revisit - Vocabulary Revision Assistant

Personal project

While the economy is hit hard by Covid-19 and it's become more unfavorable for a non-PR software engineer to secure a job in Singapore, I use my free time to work on a side-hassle alongside my job hunting during this period.

Revisit is a web application that helps users to revise new vocabularies, by means of sending email to the users containing sentences in which the vocabularies are used. This effectively consolidates the memorization of words in a timely fashion.

This app is deployed at https://www.revisitvocab.com, built with Ant Design Pro (a React boilerplate) for frontend, Django for Backend, MySQL and Redis for Database and deployed under DigitalOcean Kubernetes that lays the infrastructure for future scaling.

Patient Monitoring System

Conex Systems and Services

As a matter of fact, in the hospital there are patients who are so ill that their mobility is greatly hindered, and they face a high fall risk, meaning the chance of them falling down by getting out of bed is high. To help prevent patient falling from happening, we rolled out a patient activitiy monitoring system. In each bed we place a raspberry pi attached with camera to capture the activity of the patient, the camera feed will be passed to the Pi, which analyses and detects movements if any. When bed-exit movement is detected, Pi will send a signal to backend, which then will alert the nurses through a physical alarm and/or the frontend graphical user interface.

In this project, my role was to improve system performance, user experience and fault-tolerance by adding new functionalities and refining codebase across the graphical UI and Python backend.

Warehouse Logistic Tracking System

Conex Systems and Services

We were building an end-to-end system that helps better track the inventory and logistics of a local supplier business that manages acquisition of food and raw ingredients to restaurants and hotels. The client purchases a few thousands of different items from over 300 oversea suppliers, and their everyday inbound and outbound items required a smoother and easier way to keep track of. We built an end-to-end system capable of issuing and scanning barcodes, such that each item can be pasted with a barcode sticker, which will be subsequently scanned to facilitate recording.

I took over the entire project, picked up ASP.NET(C# framework) to build scanner device's mobile frontend, server endpoints, refined MSSQL server's database transactions. I also integrated the system with the peripheral devices such as the barcode printer and Accpac system.

Registration Page (React.js)

Freelance Project

I was approached by nodeflair's startup founder, a fellow university-mate of mine, to build an interactive multi-stage registration page using react. I spent a couple of days during my year 4 mid-term period and managed to complete the task.

To my honour, they are still using this same component as their registration page as of this date. You can view the registration page here.
