Approach

Turning research into resilient products for protocols, wallets, and agent networks.

I treat agentic infrastructure as a systems problem. That means marrying protocol design, simulation, and user experience so that the people operating decentralized systems can trust what their agents are doing—and why.

Recent work spans trust infrastructure for agentic economies at Lyneth, ERC-8004 semantic discovery and A2A interface through CompassDAO, and agent0 SDK contributions for vector search.

If you're designing resilient protocol operations, building agent registries, or experimenting with ERC-8004-powered ecosystems, I'd love to compare notes.

Roles and Work with lasting surface area

From trust infrastructure for agentic economies to embedded wallet rails and ERC-8004 tooling, these are the most impactful collaborations I've been a part of.

Trust Infrastructure for Agentic Economies · Venice AI $20K Grant · 2025 — Present

Building trust infrastructure for agentic economies—decentralized systems that enable verifiable trust when agents replace intermediaries. As autonomous systems manage trillions in value, trust becomes the foundation for open economic networks.

Developing infrastructure on top of ERC-8004 registries for identity, reputation, and validation. We analyze feedback history, owner wallet patterns, and interaction quality to surface meaningful reputation signals that enable agents to make informed trust decisions.

Building comprehensive protection mechanisms: sybil resistance through wallet clustering and behavior analysis, griefing protection by detecting coordinated attacks, and validation systems that cross-reference multiple trust signals to verify agent behavior and capabilities.

Currently working with early partners across DeFi and agent infrastructure; enabling verifiable trust at scale so agents can operate independently in open networks without requiring blind faith.

0em Labs
0em Labs · Engineering Intern

Fullstack Web3 Engineering and Devops · 2025

Built payment rails across the 0em product suite—usage-based LLM billing via Privy and social-login smart wallets that hide web3 complexity for regular users.

Designed a custodial wallet SDK with fine-grained delegation and on-chain rate limiting so autonomous agents can act on behalf of users without compromising safety.

Enabled x402 monetisation for MCP providers, balancing developer ergonomics with compliance-grade controls.

Agent0 · Open Source Contributor

ERC-8004 SDK & Semantic Search · 2024 — Present

Built semantic search service for ERC-8004 agents using Subgraph, Cloudflare Workers, Venice AI embeddings, and Pinecone vector storage, enabling natural language discovery of agents across multiple networks.

Developed automated indexing system with cron-based sync, queue-based processing, and D1 state management to keep the search index synchronized with on-chain agent registrations in real-time.

Contributed semantic search integration to the TypeScript SDK, including filter conversion utilities, response mapping, and multi-chain search capabilities that enable developers to query agents using natural language.

Research threads and side quests

What I'm experimenting with when I'm not shipping production code.

EIP-7702 & Delegation

Exploring how delegated agents can execute trustworthy financial flows with human-readable guarantees and safety rails.

ERC-8004 Trust Scoring Research

Prototyping economic incentives for high quality feedback, contestable feedback loops, and signal aggregation so ERC-8004 agents can be ranked on transparency and reliability.

agent0 SDK open source contributions

Contributing vector indexing and semantic search tooling to the agent0 ERC-8004 TypeScript SDK, allowing agents to search for agents semantically.
