Log

Everything shipped since the first internship in 2023, newest first: contracts deployed, packages published, prizes, grants and roles. Whatever can be linked, is.

  1. Selected

    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.

  2. Grant

    Stellar Instaward — Stellar 37°

    Plina Finance took an Instaward — the Stellar Regional Chapter's fast-track funding for early-stage builders — through Stellar 37°, the acceleration program NearX runs with the Stellar Development Foundation.

  3. Production

    Prelúdio

    Yalla's first event run end to end in production: 113 tickets across 8 lots, 98 people through the door, 257 bar vouchers redeemed with none expired, and a peak of 39 check-ins in one hour.

  4. Role

    CTO — Plina Finance

    Took over the on-chain architecture for institutional tokenization of credit rights on Stellar.

  5. Role

    Yalla

    Started Yalla as its only engineer: on-chain ticketing for Brazilian event producers, from the Soroban contracts up through the API, the producer panel, the design system and the AWS pipeline.

  6. Deploy

    MomentNFT

    ERC-721 on Monad testnet enforcing a one-mint-per-UTC-day invariant on-chain, with the public feed read straight from contract events.

  7. Prize

    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.

  8. Release

    @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.

  9. Release

    Karn Protocol

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

  10. Role

    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.

  11. Prize

    Nola

    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: I joined Nola as a full-stack intern right after.

  12. Role

    Nola

    Full-stack intern: automated testing across React, Node.js and React Native — Jest, Vitest and Cypress — plus cross-stack debugging that cut crash rates.

  13. Prize

    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. My first hackathon, built in two days.

  14. Role

    Beplauze

    First internship, front-end: led the migration to microfrontends with Astro and built a 40+ component React library documented in Storybook.

  15. Role

    CAPGov

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