Block Chain Engineer

Senior Solana engineer with 5+ years in Web3, building secure on-chain programs and backend infrastructure in Rust.


Currently at D3, I build and harden Anchor programs for staking, cross-chain proxies, and NFT marketplaces. My focus is security: replay-resistant PDAs, nonce enforcement, domain-separated signatures, and validated treasury flows. I also build the Solana indexers and execution services behind them (Token-2022, historical backfills, event pipelines), and led a production migration from web3.js to Solana Kit and Codama with byte-level compatibility tests.


Previously I led a team at Aerius Labs, shipping ZK proof aggregation in Rust and multi-sig bridges connecting TON, Ethereum, and Solana. At Electron Labs I built a NEAR–Cosmos IBC bridge. I'm also an open-source contributor to the Solana Foundation.


Looking for remote Rust, Solana, or protocol engineering roles with US, UK, or EU teams.

Experience

Senior Solana Engineer
D3 Inc
2025 - 2026
- Built and hardened Rust/Anchor programs for DAV staking: position NFTs, reward distribution, unstaking, recovery paths, and LayerZero V2 cross-chain messaging. - Secured cross-chain proxy and marketplace flows with per-domain nonces, replay-resistant PDAs, domain-separated signatures, and signed fee/treasury validation. - Built Solana execution and indexing infra for domain tokenization, bridging, marketplace events, Token-2022 transfers, and historical backfills. - Improved indexer reliability by bounding stream concurrency and fixing memory exhaustion and shutdown races. - Migrated production transaction flows from Anchor/web3.js to Solana Kit and Codama, with golden tests proving byte-level wire compatibility.
Engineering Manager
Aerius Labs
2022 - 2025
- Led two engineers building a decoupled Rust proof-aggregation backend for ZK Snap. - Contributed to Tendermint integration in Substrate and Ethereum storage proofs using SP1. - Led multi-signature bridges connecting TON with Ethereum and Solana for Jetton transfers. - Built a Solana domain-minting and marketplace system using MPL Core, address lookup tables, and versioned transactions for batched minting and primary/secondary sales.
Blockchain developer
Electron Labs
2021 - 2022
- Built a NEAR–Cosmos token bridge using Cosmos SDK, a Go NEAR light client, and a modified IBC transfer module. - Implemented Ed25519 signature verification circuits in Circom for trustless cross-chain verification.
