Problem Solving Developer in Frankfurt, Hesse, Germany

Starting with the public version of Node-Red, I was on a 2-member team for extending its architecture in order to add more capabilities required to fit in the client's requirements, in terms of cloud-aware Docker image that was able to be deployed in a CI circuit.

In addition to the architecture, we prepared a whole set of modules with functionalities of the client's legacy systems so they could be easily integrated into the new developments.

I developed several security policies that were deployed in the client's IBM Connect instance. These policies were different scenarios, but mainly related to the security (customer log in, check permissions, check relations between some data, etc.)

These policies ran in the corresponding IBM Datapower, and I created the policies and a CI circuit to be able to develop this kind of policy out of the IBM tools and easily generate the release package.

The client had several security mechanisms, some of them were custom, and what I did was create a set of small applications and add-ons to be used in the different developments for being able to verify the security before starting the execution and to extract the needed information out of it.

As part of a project for removing some legacy pieces, I did a set of applications to be run on a batch basis for extracting user credentials from LDAP and Oracle and migrate them to the destiny LDAP and database. The biggest challenge was the extraction and conversion of the secret keys (a password and a secret list of TANs) since they were encrypted in the source system in one way and they had to be encrypted in a totally different way in the destination.

Using the Postman collection already generated by the dev teams, I set in place a new automatic testing tool that uses Newman (Postman runner) to launch the tests of each application with the data according to the environment.

This tool could be used easily from the CI circuit.
