A VARA-regulated custodial crypto exchange owned end to end — core infrastructure and a provider-agnostic multi-custody layer.
Nexus is a VARA-regulated custodial cryptocurrency exchange. I engineered core infrastructure — asset management, deposit and withdrawal flows, and admin tooling — and designed a provider-agnostic multi-custody architecture.
The exchange needed to add a second custody provider (Liminal) alongside the incumbent (Fireblocks) without breaking live customer flows or coupling business logic to any single vendor.
Promoted to Team Lead & Product Owner: I own roadmap, backlog and sprint planning for a cross-functional team while staying hands-on in architecture and code review.
Introducing a custody-provider abstraction so providers can be swapped or run in parallel, with zero breaking changes to deposit/withdrawal flows already in production.
A regulated exchange with a vendor-agnostic custody layer and infrastructure hardened for audit and scale.
