Building Stablecoin-Powered Global Payments
Staff Engineer at Nclusion. Former Staff Engineer at Airbnb. I build money movement systems that use stablecoins as a core settlement layer alongside ACH, wires, PSP integrations, and cash networks.
My work spans the surrounding fintech and crypto stack: on/off-ramps, wallets, smart contracts, minting and redemption flows, ledgers, settlement, and reconciliation.
Technically, I work mostly in Python + FastAPI, Node.js, GCP / AWS, Terraform, CI/CD, observability, and security controls.

Built a fully automated unit test generation pipeline using LangGraph, GPT, and Claude at Airbnb. Generated tests outperformed tools like Copilot Chat.
