Solution Architect / Technical Lead

Environment: ASP.NET Core MVC and API, HTML5, JavaScript and Typescript, Angular, MongoDB, Docker, NodeJS, Nginx, React, AWS API gateway, Google Kubernetes, OAuth and OpenID, Git, VS Code, Social Logins

Responsibilities:

• We design the application from scratch taking consideration the speed, scalability and reusability, maintenance, easy to debug, can deploy or work to any cloud provider, security and audit, fault isolation, continuous delivery
• Implement the application in microservice architecture. Each service is small and has its own single responsibility.
• Database and programming language are determine base on the microservice requirement
• We maximize the OpenID and OAuth protocol for the authentication and authorization
• Continuous deployment is achieve by using docker, automated testing and google kubernetes
• We use Angular 4, React and HTML5 for the front-end. Front-end can only access the API through API gateway. By doing these, we can masked and add security on the microservices API like SSL offloading.
• In long term, the application will be sustain by google ads and paid subscription. So we integrate the Braintree payment gateway to handle all the payments and subscriptions
