At Fujitsu, I contributed to Virtuora NC, an OpenDaylight-based SDN controller. My work covered Northbound, multi-layer path computation, and topology projects.

Topology

A module that discovers physical network inventory and builds a topology representation. I worked on a physical-topology visualization feature across abstraction layers to pinpoint network alarm events.

Multi-layer PCE

A path computation engine responsible for creating service routes across network resources. I implemented constraint-based path-calculation features and modeled new network devices in system databases to extend controller capabilities.

Northbound

A user-facing GUI component for system interactions. I designed request forms and API endpoints, including translation of vendor-neutral OpenROADM service requests into an internal representation.

Tech stack: Java, Python, JanusGraph, Cassandra, and OpenDaylight.
