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.

Selected Work

Stablecoin Payment Platform

Built a cross-border payment platform using stablecoins as a settlement layer. Integrated Bridge, Coins.ph, Fireblocks, Circle, Persona, and Nominis across on/off-ramps, custody, KYB, address risk screening, ledgering, settlement, reconciliation, and payment operations.

AI-Powered Test Generation

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

CI Migration to AWS

Technical lead for end-to-end migration of 300+ CI machines to AWS EC2 at Airbnb. Designed the system topology with Terraform, reduced upgrade time from weeks to hours, and completed the migration with zero incidents.
