## Work Experience
### Senior Software Developer @ Stellar Development Foundation
Jan 2023 – Present | San Francisco Bay Area
Stellar Laboratory (lab.stellar.org) is an open-source developer toolkit for the Stellar ecosystem. It allows developers to explore networks, build and submit transactions, invoke smart contracts, inspect contract storage, and debug interactions without needing to write client-side code.

— Designed and implemented Stellar Laboratory’s advanced invoke-contract functionality, which dynamically generates UI forms from a JSON schema and maps user-entered native values into Soroban-compatible smart-contract values. Open-sourced the implementation, which is now integrated by external developers including Aha Labs and OpenZeppelin.
— Implemented features across contract storage, transaction building, keypair utilities, and network inspection tools to deliver consistent improvements to stability, DX, and smart-contract workflow

In October 2020, I joined Vibrant (now rebranded as Vesseo, vesseoapp.com), a mobile wallet app that helps Argentines protect their money from inflation by providing access to US digital tokens like USDC. Since then, the app has expanded to the USA, Mexico, and Ukraine, introducing features like cross-border remittances, cash in/out via MGI, and stablecoin-based wages for Argentines.

— Led development of cross-border remittances, send to phone number, cash-in/out flows, and stablecoin salary features.
— Collaborated with product to shape roadmap; became de-facto lead engineer by 2022.
— Enhanced app stability (add a metric if you have one).
