Employment
Experience
- Crawler of eCommerce Websites (via Toptal) (Development)
This was the first project/engagement that I gained via Toptal. It involved building a crawler to scrape products of certain brands from specific eCommerce websites.
Highlights of My Project Contributions:
1. Utilize a proxy service to solve the anti-crawling mechanisms of these eCommerce websites thoroughly.
2. Improve the speed of the crawler significantly by getting data from the product search result pages instead of scraping product detail pages one by one.
3. Create a website for users to visualize data, download data aggregations, check the status of the crawler, and manage users.
4. Create a CI/CD process based on CircleCI and AWS Elastic Container Service which improved the efficiency of development and deployment.
5. Introduce a mechanism to integrate our system with AWS Elastic Container Service which will be responsible to scale the EC2 instances used for crawling; only let them start when the crawler is running and scale the number of ECS services to 0 when crawling is finished. It will help save a significant amount in costs. - FileGear: Private Cloud Storage Hosted at Home (Development)https://www.kickstarter.com/projects/50808900/the-worlds-fastest-photo-music-and-document-organi/description
This project involved building a private cloud storage platform that wanted to provide an easy set up of a very accessible and home-based cloud storage solution.
I developed most of the front-end functionality including file-and-folder uploads, drag-n-drop, copy, move, uploads, file tree, explorer, image navigator, and more. I also developed a reusable UI component set based on Material Design.
For the back-end part, I invented a progressive file hash calculation algorithm which improves the file upload experience a lot. - Rhinobird: a Tool for Teamwork (Development)https://github.com/rhinobird-io
This project involved an open-sourced mutual benefit tool for teamwork.
I created a web-based calendar for users to manage and share their activities, where users can also drag-n-drog around to easily create and update activities. I also supported a real-time chat tool similar to Slack. - Sybase ORM (Development)
I created a Sybase database object-relational mapping tool.
- Angular Infinite Scroll (Development)https://github.com/RonaldoLee/angular-mobile-infinite-scroll
I developed an AngularJS component for infinite scrolling.
- Company's React Foundation Library (Development)
This is a foundation toolkit based on React and it's shared by all cloud experiences at my current company. I participated in the design and development of components and also improved the CI/CD process.
