Sr. DevOps Engineer
[May 2021 - Jun 2023] 2 years
As a senior DevOps Engineer, I was responsible for designing and implementing complex CI/CD pipelines and architecting scalable and resilient infrastructure using AWS CloudFormation and Terraform.
During my time working for Culture AMP, we designed and deployed a self-service portal using Ansible, Python, Jenkins, PowerShell, and AWS CloudFormation to help the development and infrastructure team release and speed up the process of delivering new applications.
In this portal, the engineers could launch new EC2 instances as well as AWS Lambdas using a drop-down list.
Apart from that, my responsibilities were evaluating new technologies, establishing best practices, optimizing cloud costs, and implementing security best practices. Also, I was leading the K8s project.

The Ticketek website during major events could receive millions of visits per day, especially during peak ticket sale periods or when highly anticipated events are announced.
I was responsible for ensuring the reliability, scalability, and performance of production systems which include designing and implementing resilient architectures, establishing, and monitoring service level objectives (SLOs) and error budgets, conducting incident management and postmortems to drive continuous improvement, and automating operational tasks to minimize manual intervention.
I was part of a project to automate the whole production release in the UK which involved designing Continuous Integration (shared repository), Continuous Delivery (automating the software release process such as automated deployment, testing, and configuration processes) and Continuous Deployment (every change that passes automated tests is automatically deployed to production without manual intervention).
