Rust Engineer · RPC Infrastructure, Runtimes & Cryptography

Barcelona, Spain · works ET hours

Mid-senior Rust engineer with 6+ years shipping production blockchain protocols, RPC/API infrastructure, and cryptographic systems. I build at the runtime and node level — custom blockchain runtimes, JSON-RPC services, on-chain data indexing, and applied cryptography — working directly with client teams under a test-driven, documentation-first process.

Experience

qaul.net Current Senior Rust Engineer 2022 — Present

Lead contributor on the networking and cryptography stack of an internet-independent, peer-to-peer messenger built on libp2p (Rust + Flutter). qaul.net lets devices communicate directly with one another, with no servers and no internet. qaul/qaul.net ↗

Independent Rust Engineer & Consultant · 2022 — 2026

Quantus Network Senior Rust Engineer 2025 — 2026

Built a post-quantum blockchain runtime; authored reversible transactions and implemented private transactions using zero-knowledge proofs — heavy applied-cryptography and security work.

Autonomys (Subspace Labs) Protocol Engineer 2024 — 2025

Developed protocol, node backend, and RPC/desktop client features for a decentralized storage network, working across the runtime and node-services layers.

Freeverse Senior Rust Engineer 2023 — 2024

Led development of LAOS, an EVM-based Layer 1 for cross-chain digital assets — runtime design, RPC compatibility, and on-chain data handling.

Enjin Rust Engineer 2022 — 2024

Launched a layer-zero relay chain with parachains; built lazy and multi-block storage migrations, cross-chain messaging (XCM), a trustless bridge, and internal tooling.

Polimec Senior Substrate Engineer 2025

Delivered core runtime features for the Polimec on-chain fundraising protocol.

Limechain Blockchain Engineer 2020 — 2022

Owned features end-to-end from requirements through design, implementation, and testing. Delivered 3 Web3 Foundation grants and researched alternative approaches to building blockchain runtimes.

Projects

SubEth — Ethereum JSON-RPC adapter & indexer 2024 — Present

A Rust service that lets any blockchain expose a standard Ethereum JSON-RPC interface — translating and indexing on-chain data so existing developer tooling works unchanged. subclone/subeth ↗

Open Source 2021 — Present

Contributor to polkadot-sdk, substrate, alloy, and relm4.
