I attended The University of Texas at Austin to complete an intensive six-month program in Full-Stack Web Development. The course emphasized the React framework but also included MongoDB, Node, Express, JavaScript, SQL, and other modern tools. After graduating, I founded my own company, Pulse Design, where I built tailored web solutions for physicians across the U.S. I consulted directly with clients, designed UI/UX, and developed scalable applications to help streamline their processes and grow their practices.
Building on that foundation, I transitioned into Site Reliability Engineering and DevOps roles focused on cloud-native infrastructure and observability. I worked with Kubernetes and AWS to deliver reliable and scalable systems, designed CI/CD pipelines with GitHub Actions and ArgoCD, and implemented monitoring and alerting with Grafana, Prometheus, and OpenSearch. My experience bridges development, operations, and business ownership, enabling me to deliver solutions that are technically sound and aligned with organizational goals.
