Alex Metelli

I’m a backend software engineer with 5 years of experience building backend systems, developer infrastructure, and AI tooling for agentic workflows. I’m strongest in Rust, TypeScript, Python, Go, and distributed systems, with a focus on developer productivity and reliability.

At Nethermind (remote, Apr 2024 – Jun 2026), I built backend systems and developer tooling in Rust, TypeScript, Python, Cairo, and Solidity. I developed AggSandbox, maintained Voyager Verifier with compiler compatibility and diagnostics improvements, and contributed verification support via Starknet Foundry. I also built cross-chain messaging and local testing/infrastructure validation integrations across Starknet, LayerZero, Hyperlane, AggLayer, and EVM ecosystems.

Recently, I’ve focused on AI-assisted engineering workflows and tools for automation, validation, observability, traceability, controlled execution, and developer productivity. I built AgentReceipt (signed, hash-chained local-first review receipts), Skills Doctor (CLI auditing and repair handoff), and RitualAI (local prompt-history mining into reusable, validated workflow patterns).

As a Founder & Lead Developer at ScopePilot (remote, 2026 – Present), I ship a TypeScript/Bun product for proposal scoping, pricing workflows, approvals, revisions, reporting, and automated quality gates. I bring that same engineering rigor to OSS contributions—shipping improvements across verification, tooling, indexing/devnet integration, and developer experience—and I’m now seeking fully remote backend, platform, developer tools, or AI tooling roles.
