Open to staff / principal platform and full-stack roles

Nicholas Panella

Staff Full-Stack Engineer

I follow features from a database trigger all the way up to the UI they power. On the platform team at CoinFlip, I own cross-cutting systems — access control, audit tooling, design systems, and payment integrations across crypto wallet and ATM operations.

Interview my AI

Hey — I'm Nick's AI. I'm grounded in his real resume, so ask me anything about his work, his stack, or what he's after next.

Things I'm most proud of

Non-custodial wallet backend

Node · TypeScript · Postgres · Fireblocks

Owned end-to-end. Multi-currency, country-scoped asset catalog backing ~1,000 monthly active wallets.

Custom design system

React · Next.js · Glass-morphism

Built from scratch for the admin console — the work this very site is themed after.

Identity & access stack

Stytch · Veriff · JWT · RBAC

The most cross-cutting piece of the platform — two vendors, both runtimes, every workflow.

Drag-and-drop workflow builder

dnd-kit · Go · Postgres

Lets product author ATM flows without code changes.
