Meet Your Team: Cloud Engineering

The Cloud Engineering team forms the backbone of adjoe's tech infrastructure. We handle over 5 billion daily API requests through hybrid infrastructure that combines AWS managed services with self-hosted open-source tech like Kubernetes and Apache foundation projects. We continuously evaluate when to use self-hosted versus managed services to achieve the best cost-efficiency ratio and reduce our monthly $300K hosting costs.

We've implemented infrastructure as code through Terraform, managing deployments via Kubernetes while engineering comprehensive monitoring systems using Prometheus, Grafana, and ELKstack.

The cloud engineers also provide adjoe's developers with working solutions, knowledge, and documentation that gives them autonomy to work on infrastructure while ensuring high-quality service and minimal downtime for continued business growth.
