Senior Backend Engineer at LI.FI, scaling services across 3M+ tokens and 60+ DEXs.

At LI.FI, I work on the Backend Core team, scaling services that aggregate real-time data for over 3M tokens across 60+ DEXs. I’ve optimized core data processing paths to make incident management 2–3x faster while maintaining financial accuracy.

At Nexera Finance - Evergon Labs, I developed cloud-native services for real-world asset tokenization and DeFi products. I also worked as a tech lead in product squads and developed 12 domain-driven services exposing business REST APIs.

As an independent Web3 Blockend Engineer, I worked on blockchain contracts, web services and dApps. My EVM Bounty Granter dApp won three sponsor prizes at ETHOnline 2022, and I contributed to the Stashh.io NFT marketplace.

At Amdocs, I progressed from backend engineering into software architecture and engineering management for Care & Commerce digital services. Earlier, at Streamezzo, I developed Java backend services and connectors for mobile applications.
