Our Engineering team
Our Engineering team is responsible for developing our SaaS platform and building a comprehensive and user-friendly product.
Keystone AI engineers participate in the entire application development lifecycle, focusing on design, coding, and keeping the production platform up and running. They can be specialized, but there is no strict separation between the backend and the frontend.
We value user-centricity and pragmatism: we choose the most relevant tools for the problem we have to solve, understanding the strengths and constraints of each technology.
Our engineering culture also values curiosity, humility, trust, ownership and team spirit.
Our technical stack is C# on .NET Core Linux, React, TypeScript, PostgreSQL, Google Cloud Platform, Docker, Kubernetes, Terraform, RabbitMQ and Circle CI.
