About OntoTech

We’re an open and collaborative bunch who care deeply about creating an amazing team for each and every person to work in. We understand the best way to create a product that our customers love is to create a team in which people love working.

As you would expect from a tech-driven company we’re working across a number of exciting technologies. We’re cloud-based at heart, focussed around AWS. Our back-end technology of choice is Python using the Django framework with our front end written in React with Redux. We also use GraphQL for our APIs. Our apps are native, written in Swift using SwiftUI and Kotlin respectively. We have actively started our journey to break down our monolith into micro-services and expect to continue this in 2022. We’ve initially selected Python and FastAPI to do this
