Abstract

I build backend services and the infrastructure that runs them. My work connects application logic with cloud operations: APIs, databases, containers, and the pipelines that bring them together.

At ProjectX, I mainly work with AWS, Azure, GCP, Terraform, Kubernetes, Docker and Golang. Across my projects, the aim is consistent: systems that are reproducible, understandable, and easier to maintain.

Selected work

From recoverable data pipelines to the services behind an event.

Event-driven task automation

triggerd

A Go daemon that turns ntfy notifications into allowlisted operating-system tasks. An outbound subscription connects events to systemd, launchd, or Windows Task Scheduler, with bounded dispatch and explicit failure handling.
