christian sauciuc
Backend software engineer in fintech, building the APIs and services that banks and payment platforms run on.
I work on the load-bearing parts of software — card systems, core banking, and the pipelines that ship them. Mostly Go and Java. Off the clock, a homelab and too much self-hosting.
