When designing infrastructure as code, I focus on standardization and modularity. This means creating reusable templates and modules that can be easily adjusted for different environments. I also emphasize the importance of documentation to ensure that fellow engineers can understand and leverage the infrastructure effectively.

In my previous role, I extensively used AWS services such as EC2 for compute resources, S3 for storage, and Lambda for serverless computing. I have experience setting up IAM roles for security and using Route 53 for DNS management, all of which are crucial for building reliable applications.

I've built and maintained CI/CD pipelines using tools like Jenkins and GitLab CI. My focus is on automation to streamline the development process, ensuring that code can be deployed quickly and safely, while also integrating automated testing at various stages to maintain high quality.

I prioritize quick, effective communication during incidents, utilizing platforms like PagerDuty for alerting. My goal is to quickly identify root causes and implement fixes while documenting learnings to improve our incident response processes over time.

I employ a least-privilege access model using IAM roles, regularly audit our cloud configurations, and implement security controls such as VPCs and security groups. Moreover, I ensure that all data is encrypted in transit and at rest to protect sensitive information.

I ensure observability by implementing robust logging and monitoring solutions like Prometheus and Grafana. This allows for real-time insights into system performance and helps quickly diagnose issues before they impact end users.

In my last position, I created a developer portal that consolidated tools and resources. This significantly reduced the onboarding time for new team members and allowed engineers to quickly access necessary tools, thereby enhancing productivity across the team.

Automation is a cornerstone of DevOps; it reduces manual errors, accelerates processes, and allows teams to focus on higher-level tasks. By automating testing and deployment, I can ensure quicker releases with greater confidence in quality.

One challenge I faced was resistance to change from team members accustomed to traditional processes. I addressed this by providing training and demonstrating the benefits of DevOps, which ultimately helped in getting buy-in and improving collaboration.

I'm drawn to 9fin because of its innovative approach to transforming the debt capital markets. The opportunity to empower developers while leveraging cutting-edge technology in such an impactful sector excites me.
