Mobile Engineer · Backend Engineer · Curitiba, Brazil
I'm a Mobile Engineer focused on building consumer fintech and neobank products. I work across mobile, backend, blockchain infrastructure, and AI integrations, with experience building crypto wallets, payments, financial products, AI-powered applications, and Ethereum smart contracts. I've built production systems used by millions and am a multiple hackathon winner.
I believe technology can provide greater economic freedom and give people more control, access, and freedom over their finances.
Fluent in English and Russian, conversational in Spanish, and currently learning Portuguese. Active in tech and blockchain meetups and hackathons.
Outside of work: travel, photography, King Gizzard & The Lizard Wizard, and a belief in privacy tech.
