I arrived at the creation of the infrastructure team, when the company realized that it needed to have a dedicated team to manage the infrastructure. We are now a team of 3 people, and we are responsible for the entire infrastructure of Shine. My missions can be slight changes (like adding a optional feature to an existing resource), big projects (like implementing a complete hosting solution on top of GCP with Terraform), or to prepare the future by creating tailored Terraform modules for the developers. We rely heavily on tools like Terraform, GCP, ElasticSeach, Grafana.

My responsibilities cover:

• Managing Shine’s entire infrastructure in GCP, including containers (serverless), instances (MIG), queues, databases, and load-balancers.
• Transitioning infrastructure management from nothing to Terraform, by providing several repositories in a self-service mode and with helpful and tailored modules.
• Automating processes via GitHub Actions.
• Setting up monitoring with Grafana (in Terraform): managing logs, metrics, and dashboards.

I was the first Site Reliability Engineer when we started the Platform team. At that time, our team grew to 12 members, and we handled infrastructure (mostly cloud-based), security, data, and enhancing the developer experience.

We relied on Terraform, GCP, CloudFlare, Datadog, and Python for our work.

My responsibilities included:

• Writing Python scripts.
• Automating processes via GitHub Actions.
• Setting up monitoring with Datadog (in Terraform): managing logs, metrics, and dashboards.
• Being on-call for Level 2 support.
