About

I'm 27 years old and Portuguese. Between 2019 and 2022, while completing my university studies, I participated in multiple hackathons and launched my first company. In 2022, I discovered the Web3 world, and since then I've been working as a full-stack Web3 developer — building my own decentralized applications as well as working on paid projects for clients.

What I've Built

From building my own ideas to delivering paid client projects — here's what I've created.

Own project
Hand of God

Hand of God

A seigniorage-based protocol where emissions, bond thresholds, and key monetary parameters were dynamically adjusted by an AI decision engine. A backend bot collected protocol metrics and sent them to an AI model via API, which returned optimized values to be applied on-chain. Most of the protocol’s operational logic was autonomously managed by AI. At its peak, the protocol reached over $29M TVL.

Own project
MilkIt

MilkIt

Milkit was a peer-to-peer cash system that combined Bitcoin-style emission mechanics with community-driven incentives on Sonic. On launch day, the protocol generated over $280K in fees and the main liquidity pair reached nearly $1M in TVL. The project was eventually discontinued due to performance limitations of the Sonic network at the time.

Own project
SonicSphere

SonicSphere

SonicSphere was a DeFi protocol inspired by well-known models such as Solidly, OHM, Beradrome, and Liquid Driver. The project conducted a token generation event but only reached ~10% of the target (≈600k $S tokens). Because the target requirements were not met, all funds were returned to investors.

Typescript
Client work
abcSWPX/abcNILE

abcSWPX/abcNILE

Developed autocompounders for liquid wrappers like abcNILE and abcSWPX for Abacus Finance.

Solidity
Own project
veGHOG - veNFTs

veGHOG - veNFTs

Is a soulbound veNFT received when locking GHOG into the Hand of God protocol. It grants governance rights, yield-boosting power, and access to the emissions system. Each veGHOG belongs to one of three DerpeVerse factions (revealed on March 4, 2026). These NFTs are utility-focused, non-transferable, and designed for governance and yield—not collectibles.

Client work
Sonic Index Contract

Sonic Index Contract

Built the smart contracts that display Sonic Index veNFT stats based on the Sonic Index Team requested design.

Hackathons

Entrepreneurial by Nature

During university, I focused on building my own ideas. I joined hackathons to turn concepts into real prototypes.
