Canvas has improved a lot from where it was when it was launched 2 yrs ago (Oct 2018). I have built condition monitoring dashboards using Canvas. I have an eye for aesthetics and with your guidance we should be able to make your current dashboards look good!

On the other hand, in general, I will be happy to discuss and implement your requirements and a variety of user stories using all the cool features provided by Kibana.
I have worked on various exciting projects where I had to build intuitive dashboards. I have created advanced visualizations such as Heatmaps, Sankey charts, Milestone charts, Swimlanes, Enhanced tables, Timelion etc.
Created advanced Alerts on streaming data, worked with Elastic ML, ECS (Elastic Common Schema), and Canvas (infographics in Kibana).
