API integration is the core of most of my projects. It provides the groundwork to further application development. Throughout the last years, I worked with multiple API Gateway providers such as AWS API Gateway, TIBCO Mashery, WSO2 API Gateway as well as WSO2 Ballerina to provide a good foundation for public interfaces.

Node, especially with the focus on serverless, plays an important role in todays tasks. Most integrations use some kind of scripting, either provide the full API like with Express.js or just to use it as function layer (AWS Lambda). Most event based system also integrate really will into this ecosystem.

Due to the current service landscape of the customer, we found that most commercially available API gateways are not prepared to provide its functionality across multiple regions/continents within a consolidated environment. Therefore we initiated this project to provide a basic API gateway (as a layer architecture) to provide API functionality internally as well as expose a certain subset publicly. All this was created on top of an existing ESB architecture, which also provided basic building blocks for deployment and monitoring.

Callable is a SaaS project which aims to provide a serverless integration for SAP systems. It provides OpenAPI access to any SAP-based system through SAP-native mechanisms (SAP JCO). Through the transformation from SAP JCO types into restful interfaces, interacting with such systems is opened to a much broader audience. This system is completely built on serverless components to keep the offset cost at a bare minimum. The licensing also follows a pay-per-use model.
