I build
onchain products.

Founder based in Lisbon. 7 years shipping consumer crypto — from token-gated infrastructure to NFT platforms and loyalty systems. Now building Checkr — an attention intelligence layer that tells onchain agents why tokens move, not just that they moved.

Checkr ↗

Attention intelligence layer for onchain agents. Processing 10K+ daily social signals across Base to model whether a narrative is self-sustaining or in decay — and exposing it as API skills powered by x402. Any agent can pull Checkr's intelligence with a single HTTP call.

Built proprietary models (Social RSI, attention intelligence score, narrative decay) and trained them on accumulation patterns and attention–price divergences. Shipped the full production stack solo: desktop app, mini-app, public API, and ML pipelines.

What I'm into.

🤖 Agent Economy
Agents will outnumber humans onchain. Building the infrastructure that lets them coordinate: x402 payments, LLM skills, attention signals, reputation.
📡 Social Intelligence
Most analytics count events. I model dynamics — narrative branching, organic vs manufactured conviction, attention decay. The signals that move markets before charts react.
⛓️ Consumer Crypto
7 years of lesson: crypto products need to feel invisible. The infrastructure disappears, the user just feels the value.
🧠 0→1
The obsession. Concept to market with lean teams. Ship fast, learn faster.
