Backend engineer building reliable publishing, gateway, and auth systems.
I design and build backend systems that handle content publishing at scale, manage API gateways with strict access control, and implement authorization frameworks for distributed services.
This is my engineering journal — where I write about systems architecture, infrastructure decisions, Go service patterns, and the occasional deep dive into building durable, observable products in public.
