Find a professional database developer in WA

We are a manufacturer of ultra pure water systems for use in laboratories, hospitals, universities, schools, etc and as part of our continual improvement, we remotely monitor some of our customers water systems and store process data. We currently use two different platforms for this. We use Click PLC’s and InHand routers via mobile phone network for the remote monitoring. The first solution we used was an IoT gateway by Phoenix Contact. The data is stored and viewed on a Phoenix Contact platform (https://tsd.proficloud.io) and is a bit too restrictive for us and how we want to manage the data. We then moved to using ThingsBoard and have a ThingsBoard server running on our premises. The issue we have with this is that the front-end interface is not as nice as the Phoenix Contact one (which is a cut-down version of Grafana). What we would like to do is have the front-end Grafana interface, but have the data being stored on our local server. I believe this could be achieved in 2 different ways – one by still using ThingsBoard to store the data (PostgreSQL) and then pass through to Grafana to display, or get rid of ThingsBoard completely and use a different database to store the data while displaying on Grafana. I would prefer to remove ThingsBoard as we are paying a monthly fee for this license. We currently use MQTT to send the data from the InHand router to ThingsBoard.
