I have worked with creating Tableau reports and being the internal support person for reporting needs for an organization; both for supporting users using Tableau, and for assistance in extracting reports from the existing data structure.
I’ve worked with MySQL and PostgreSQL; often directly with SQL queries.
Elasticsearch and Kibana are other tools I have used.
At one organization the search feature was ported over from solr to elasticsearch, and I assisted in expanding the indexing definitions.
I have done somethings with network graphs.
A bit of Python network graph data visualization, Kibana, and Gephi.
