Hey,
I just go through the requirement and I understand you need SPARQL expert.
I have 6 month experience in sparkle/ Sparql. In my project I implemented RDF dataset and related graphs and GraphDB.
Client requirement was like search a medicine based on some character.
I have also the knowledge of Sql, Mysql and many more databases. So, I am able to do your project.
Can you please let me know when we can discuss about your project.
