- SurvivorPlan (Development)http://survivorplan.io/
SurvivorPlan is the next generation solution for clinician-friendly, patient-empowering cancer survivorship care planning. Intelligent, easy-to-adopt, and cost-effective, SurvivorPlan enables cancer centers to meet CoC Survivorship Care Plan Standards while creating personalized, living solutions for individual cancer survivors and their care teams.
On this project, I architected and developed the API layer of the application using Node.js and Swagger. Additionally, I developed the deployment process using AWS Elastic Beanstalk and Docker. - Johnson Health Tech. Co., Ltd. (Development)
At Johnson Health Tech, I built a team of sixteen developers using modern development stacks and platforms.
Legacy applications were ported to Amazon Web Services Elastic Beanstalk servers using Docker, new applications were developed with API-centric architectures using Node.js, Express, MongoDB, MySQL, Swagger, and Docker.
The front-end applications were developed using Angular and Bootstrap and deployed as static applications to CDN services with a limited need for servers. Some lightweight services were migrated to Amazon Lambda functions and development pipelines were automated to improve overhead and need to separate system administration.
