My name is Juan Sebastián, but everyone calls me Sebas.
I am passionate about creating proofs of concept using diverse technologies, learning from them, and applying those insights to both personal projects and my professional work.
While I consider myself a Fullstack Developer (as I am proficient in frontend), my primary focus is backend development, server administration (both cloud and on-premise), and task automation through CI/CD.
I maintain a Home Lab running Ubuntu Server, hosting Docker containers with services such as Bind9 for DNS resolution, Grafana and Prometheus for monitoring, FreePBX + Asterisk for VoIP testing, and Nextcloud for file storage.
Additionally, I operate a home Kubernetes cluster using three mini PCs: one acting as the master node and the other two as worker nodes. One node runs ArgoCD for manifest synchronization, while the other utilizes Nginx as a load balancer.
Beyond the screen, I am an avid student of Theology and Ancient Scripture. I enjoy writing about the insights I gather from my readings, with a particular focus on biblical Hebrew and Greek, and Book of Mormon studies. I believe that engaging with these texts in their original languages opens up a new world of meaning, nuance, and depth that enriches my perspective.
