about

I engineer backend systems, developer tooling, and distributed infrastructure โ€” things that hold up at scale.

Currently at LessonUp (via 25Friday), an EdTech platform used by teachers across Europe. I happen to also care about people, so I mentor engineers and help teams grow.

I like clean APIs, strong types, gRPC, and good coffee. Not necessarily in that order.
