Giuseppe Viggiano

Castling Lab LLC · e1

Engineer working across document intelligence, quantitative systems, and enterprise software. The person who moves first — and the one who stays when the position has to hold.

01

Castling Labs is the independent practice of Giuseppe, an engineer working across document intelligence, quantitative trading systems, and enterprise software. It's the place for projects built outside client work — slower, more deliberate, and entirely self-directed.

02

Castling is the only move in chess where two pieces move at once: the king slides to safety, the rook advances beside it.

That's the shape this practice tries to keep. Build the foundation first — the part that has to hold under pressure — and let it be what creates room to try new things. Not speed for its own sake, and not caution for its own sake either. Both, in the right order.
