Hello
I have experience with OPA for a bill payment gateway solution co-working with Oracle architects and SRE on this platform.
I am an experienced professional in software development and architecture, microservices, soa, docker, podman, restful apis, java, python, nodejs, web services, cloud platforms (gcp, aws, ocp, ibm).
I can make for you a customized presentation of how OPA works in the domain that you need.
We could chat to define in more detail your requirements, scope and budget.
Best regards.
