Stellar Builder Summit 2026, São Paulo

Invited on the strength of Plina Finance: eight days in São Paulo with around 100 builders selected by NearX, Stellar's partner in Brazil. A build-first program, not a conference.

Monad Blitz Rio de Janeiro 2026

1st place with Monad Moments: one photo a day, minted as an ERC-721 whose one-per-day limit is enforced by the contract rather than the UI.

• Repo ↗

@karn_lat/protocol-sdk 0.1.0-alpha.5

Typed TypeScript SDK for the Karn contracts, with multi-wallet support for Freighter, Lobstr and xBull.

• npm ↗

Karn Protocol

Open-sourced under MIT: three Soroban contracts (Valocracy, Governor and Treasury) with 53 tests and five security findings resolved and documented.

• GitHub ↗

Karn

Founded Karn: governance infrastructure on Stellar where voting power follows contribution instead of capital, paired with a program for women in tech across Latin America.

Hackathon Nola: God Level, Code Your Futur

1st place in Nola's competition with Mise, an analytics platform for restaurants: multi-store dashboards with DeepSeek for recommendations. The win became the job at Nola.

• Repo ↗

Nola

Automated testing across React, Node.js and React Native (Jest, Vitest and Cypress), plus cross-stack debugging that cut crash rates.

Morro Makers

1st place with Jaspr, a multi-tenant AI concierge for hotels: retrieval-augmented generation over each hotel's own data, so the concierge answers from the real thing instead of inventing it.

Beplauze

Led the migration to microfrontends with Astro and built a 40+ component React library documented in Storybook.

CAPGov

Undergraduate research in ETL: the pipelines in Python and SQL that turn large public datasets into evidence policy researchers can cite.
