OneResume (Self-employed)
- Began creating oneresume.com in January 2018. It's a cross-platform hybrid app allowing anyone to create a professionally designed resume, even if they don't have any design background.

- Deployed the services to two AWS environments: QA and production. In addition to AWS EC2, I used Elastic Beanstalk, RDS, EFS, and Route 53.
