In my previous role, I designed and deployed a multi-cloud infrastructure using AWS and Azure to ensure high availability and scalability. I utilized Infrastructure as Code (IaC) tools like Terraform to automate deployments, reducing manual errors and improving efficiency. I also implemented monitoring solutions like CloudWatch and Azure Monitor to track performance and optimize resource usage. My experience includes managing hybrid environments, ensuring seamless integration between on-premises and cloud systems, and maintaining security compliance across all platforms.

When troubleshooting infrastructure issues, I follow a systematic approach. First, I gather information from monitoring tools and logs to identify the root cause. I then prioritize the issue based on its impact and urgency. For example, in a recent incident, I resolved a network latency issue by analyzing packet loss data and reconfiguring the load balancer. I also document the resolution process to create a knowledge base for future reference. Collaboration with cross-functional teams is key to ensuring a quick and effective resolution while minimizing downtime.

To ensure infrastructure security, I implement a layered defense strategy. This includes configuring firewalls, enabling encryption for data in transit and at rest, and regularly updating systems with security patches. I also enforce strict access controls using role-based access management (RBAC) and conduct periodic vulnerability assessments. In my last role, I integrated a SIEM solution to detect and respond to threats in real-time. Additionally, I ensure compliance with industry standards like ISO 27001 and GDPR to maintain a robust security posture.

I optimize infrastructure costs by leveraging auto-scaling, reserved instances, and spot instances in cloud environments. I regularly analyze usage patterns and rightsize resources to eliminate waste. For example, I reduced costs by 20% in a previous project by migrating underutilized workloads to a serverless architecture. I also use cost management tools like AWS Cost Explorer and Azure Cost Management to monitor spending and identify optimization opportunities. Balancing cost and performance requires continuous evaluation and collaboration with stakeholders to align infrastructure with business needs.

I have extensive experience with automation tools like Ansible, Puppet, and Jenkins. In my previous role, I automated the deployment of infrastructure components using Ansible playbooks, reducing deployment time by 50%. I also integrated Jenkins pipelines to enable continuous integration and delivery (CI/CD), ensuring faster and more reliable software releases. Automation has significantly improved efficiency, reduced manual errors, and allowed the team to focus on strategic tasks. I continuously explore new tools and techniques to enhance automation capabilities and streamline workflows.
