I built a static website generator as a service including backend, frontend, service architecture and asynchronous service calls to external API's as well as managing, supporting and marketing.

Appernetic is built in JavaScript and we use Angular.js for the client side, Nginx/Node.js for the server side and glue it all together with Redis, MariaDB, Stripe and Auth0. Hugo is used for fast static website generation and Git/GitHub for version control and publishing. No sensitive data such as passwords or credit card information is stored on our servers.
