I'm good at server-side scripting and infrastructure
development.
As a Site Reliability Engineer at mthmr, I was responsible for ensuring the reliability and performance of the company's infrastructure. One of my key projects was migrating the infrastructure from AWS to OCI (Oracle Cloud Infrastructure). This involved designing and implementing a new architecture that would be more cost-effective and scalable, while still meeting the company's performance requirements.

To begin the migration, I worked closely with the development team to identify the key components of the existing infrastructure, including the Postgres database, Ansible for configuration management, Github Actions for CI/CD, and Django for the web application framework. I also worked with WSGI/GUNICORN as the web server and opencv for image processing.

Once the components were identified, I designed and implemented a new architecture on OCI that leveraged the strengths of the platform. This included creating new VM instances, configuring load balancers, and setting up an autoscaling group to automatically adjust the number of instances based on traffic. I also used Terraform to automate the deployment of the infrastructure.

To ensure the reliability and performance of the new infrastructure, I implemented monitoring and alerting using tools like Grafana and Prometheus. This allowed us to proactively identify and resolve issues before they could affect the user experience.

Throughout the migration process, I worked closely with the development team to ensure that the new infrastructure was fully compatible with the existing stack. I also provided training and documentation to ensure that the team was able to effectively manage the new infrastructure going forward.

Overall, my experience at mthmr involved successfully migrating the infrastructure from AWS to OCI, while maintaining high levels of reliability and performance. The stack I worked with included Postgres, Ansible, Github Actions, Django, WSGI/GUNICORN, and opencv.
