Not everything.
The ones that matter.

Brazilian exporters and importers faced multi-day settlement cycles and high costs in trade finance operations, relying on legacy correspondent banking rails.

Designed and led the architecture of a tokenized trade finance platform built on DREX — Brazil's CBDC infrastructure. Implemented smart contract-based conditional settlement, replacing manual reconciliation with programmable money.

Reduced settlement from T+2 to near real-time. Eliminated counterparty risk through atomic delivery-versus-payment. Positioned the institution as a DREX pilot reference implementation.

SME receivables lacked liquidity and secondary market access. Traditional securitization was too slow and costly for smaller ticket sizes.

Built a tokenized receivables platform that converts trade receivables into on-chain assets with embedded compliance logic. Integrated with an AMM designed for fixed-income instruments to enable secondary market liquidity.

Enabled fractional ownership of receivables. Created new funding channels for SMEs. Generated yield-bearing on-chain assets accessible to institutional investors in a regulated framework.

The financial institution's cryptographic infrastructure — PKI, TLS, digital signatures — was entirely based on algorithms vulnerable to Harvest Now, Decrypt Later (HNDL) attacks from future quantum computers.

Led a multi-year quantum readiness program: threat modeling, cryptographic inventory, prioritization of high-risk systems, and implementation of NIST-standardized post-quantum cryptographic algorithms in critical settlement and custody systems.

Institution became one of the first in Latin America to deploy post-quantum cryptography in production financial systems. Program recognized by regulators as a reference model for sector-wide PQC migration.
