Full stack developer, 6+ years building business systems in .NET and Angular.

About

I build business systems: ERP, invoicing, online payments, inventory and approval workflows. Today I work on the commercial platforms of a retail chain with 200+ branches, from development through deployment and production monitoring, including critical incidents.

Outside work I run a homelab as infrastructure practice: Proxmox, Kubernetes with GitOps, Terraform and Ansible, with decision records and incident write-ups for what went wrong.
