This company is US startup company and at this company, I developed a TeleHealth app using ReactJs and AWS. These technologies are main ones used in this project.
Actually, this is web-based service and such the telehealth app is playing a key role in keeping doctors and patients safe and healthy during this crisis.

For this app, we used a lot of aws services, twilio service and voip service.
I was responsible for script building interfaces, the feature to export the scripts into a PDF format and face-to-face meeting service.

The team was not large and there were only six members.
The team was not large but the team culture was strict regarding to agile methodologies.
Because the project is large. If the team culture is not strict, the codebase and struture of the project would be mess.

This company provides a coupon and cashback reward service for customers.
I worked as a Senior frontend developer and they was planning to update their company sites regarding to re-design.
The period of this contract was three months.
As soon as I finished the contract period, the client suggested me work for improving the SEO of company site.
So I continued the contract for two months.
During my contract, I updated UI and SEO of company site.

The challenge at this company was to learn the SEO.
When the client assigned this task to me, I was embarrassed because it was a new technology for me.
I researched tutorials and articles for best practice and I found solutions.
Working as an SEO developer, I realized that the SEO is also important for frontend developers.
