Cofounder · Product & Design · Notus · 2023 – 2025 · São Paulo
Context
Chainless is a Brazilian crypto fintech app: KYC, PIX, and on-chain transactions in one product, treated KYC and onchain transactions as part of the product, not a wall around it.
What I did
Led product and design across the app: design management, UX, development leadership, and digital strategy. Set the bar for interface consistency and flow quality, kept the product pointed at the Brazilian market.
Outcome
Launched publicly at Blockchain Rio 2024 with full KYC, PIX + on-chain transactions, and the Dollar Income feature. 120 users onboarded on launch day. Strongest signal: building a Brazilian crypto fintech in a regulated market, with users who actually transact.
