Coded in C#/.NET using proprietary In-Memory Graph database API to combine user document information stored in graph nodes with word senses also stored in the graph to produce natural language-like English sentences. Migrated original code base from C++ to C#/.NET. To improve readability of responses, implemented techniques to limit graph traversal by ignoring output nodes mapped to temporal and other information nodes from user input(questions).

Worked on the Datumtronic Server, a windows service app designed to handle requests to traverse and add/delete nodes from the datum universe graph, and a routing service to route requests to multiple containerized instances of the server( C#/WCF). The code was later ported to gRPC.
