Andrea Gonzalez

FinTech engineering student at ESILV in Paris (class of 2027). I build risk tooling for on-chain credit and trading: read the ledger, not the report.

1st place, XRPL Lending Hackathon, Paris 2026, with Orma: $1.7k, a grant to build in NYC and a ticket to Swell.
Winner, Lending & Borrowing track, AI & Fintech XRPL Hackathon, New York 2026, with Orma Desk: $6k.
Two prizes, ETHDenver 2026, with AgentFi: 2nd place in 0G Labs' Best DeFAI and 3rd place with ADI Foundation, $2.4k in total.
Selected, TOKEN2049 Origins, Singapore 2026 (Cardano track), with Brume.

Open to risk and dev roles in crypto or fintech from 2027, anywhere.

Work

  • Orma: credit risk for locked-up XRPL lending vaults. Caught a 19.6% impairment the vault's reported value hid; the score is written on-ledger and gates deposits. Repo · Live · 40 findings
  • Orma Desk: lends XRP against XRPL vault shares at what the vault would pay out, under a risk mandate, with 2-of-3 escrow, margin calls and a hash-chained decision log. Built on Orma in New York, on Devnet. Desk · Repo · What was built at the event
  • Trade Forecast: drag the stop on the chart and the Hyperliquid position resizes so the loss at the stop never exceeds your risk, fees and slippage included. One key sends a protected bracket. Property-tested, testnet only. Repo · Live
  • Brume: negotiated exit for disputed Cardano escrows, without the arbiter. 61 mainnet escrows stuck for a median of 333 days. Repo · Paper (7 pages) · Site
  • AgentFi: marketplace where autonomous DeFi agents are owned, hired and monetized on-chain. Repo · Live
  • FlashScope: flash-loan arbitrage dashboard on Monad testnet (simulated pools), built in 8 hours at Monad Blitz. Repo · Live
  • CodeTgh: shares messages, tasks and file claims between the Claude Code sessions of a team, with a self-hosted hub, a CLI and a runner that opens reviewed pull requests. Early, pre-1.0. Repo
