Hands-on CTO & Blockchain Engineering Leader
I’m a hands-on CTO and blockchain architect with 10+ years of software engineering experience and 7+ years in technical leadership, working in crypto since 2018.
I build and scale DeFi protocols, non-custodial wallets, cross-chain systems, and smart-contract platforms, combining architecture, engineering management, product thinking, and business strategy.
Most recently, I served as CTO of Pink Wallet, owning architecture and delivery across mobile, backend, EVM, Bitcoin, Solana, TRON, XRPL, gas sponsorship, swaps, cross-chain flows, and AI-powered user features.
Previously, as CTO of Rivo & Locus, I led 25 engineers, increased team productivity by 3x, reduced salary expenses by 1.5x through team restructuring, and delivered cross-chain vaults and a mobile application with account abstraction.
I’m currently open to CTO, Head of Engineering, Engineering Director, Blockchain Architect, and Staff/Lead Smart Contract roles.
Based in Berlin, available immediately, and open to remote opportunities across Europe and internationally.

Why did the smart contract break up with the frontend? Too many unresolved dependencies.
