Red Mart

This site is an online Singapore grocery service.

I worked on this project as a senior web developer and led a team of eleven. We built this website using Ruby on Rails and React. I also hosted PostgreSQL on a Nginx server, introduced the agile methodology for product management, and utilized UML to design the process and database structure. I also wrote perfect test cases for payment.

I started this project as a web developer, eventually taking a leadership role as a lead developer in my last year on the team.

I began developing the front-end using the Create React app, which is provided by Facebook, and then later adopted Redux, Redux-saga, React Router, Axios, and more. This website was built using Python/Django and React. I also used the Django REST framework to create RESTful APIS and Django REST Framework JWT to implement token-based authentication.

Skincare Service
I'm a front-end engineer focused on building and updating the customer-facing portal.

I built a booking system and created a product listing and detail page to showcase what we're providing and what users can get from our services.
