Working now as backend developer to offer OpenAPI and GraphQL interfaces written in Python and using CQRS and Event Sourcing.

Previously I worked a couple of years developing in Java and Python mainly in internal services that consumed other internal APIs.

And before I had my longest experience to the date integrating systems and developing services in C++. That required managing redundancy and service availability management, servers (GNU/Linux) and network configuration, testing, C++ development and support to developer teams on network programming and communication issues.
