Hello Freelancers, Important: please reply only if you have experience with graph databases, I don’t want to waste your or my time for automatic bids. I’m looking for a freelancer with Neo4j/graph database experience to create Neo4j database of airports, airlines and routes connected together. Basically a big traversable graph which I can search. List of airports, airlines and routes will be provided. You will need to implement Deikstra algorithm for the shortest path search of available flights with couple of filters (sort by shortest travel time, airline rating, alliance).Please keep in mind there is min/max connection time for each airport. As far as I know shortest path algorithms (deijkstra and A*) are already packaged into Neo4j, so you it should be pretty easy to call. Final product will have simple console where I can enter origin/destination airport, date and click search. Results will include shortest path routing (I believe you can use Gephi to visualize it). Here are couple of similar projects that I've found [login to view URL] [login to view URL] [login to view URL] Now, database content Nodes- airports Attributes: AirportID Unique identifier for this airport Long name- (ex.

I have used neo4j to develop an application and later converted it to MongoDB as the usage pattern was changed. Would happy to work with this work, as I can use my experience to start on.
