Founder — Invaris Labs (Sep 2026 – Present)
- Building open-source security infrastructure for teams shipping autonomous AI agents to production.
- Built AgentSec, an adversarial framework detecting prompt injection, tool misuse, secret leakage, memory poisoning, and MCP vulnerabilities — OWASP-mapped, with GitHub Action and SARIF integration.
- Built Agent Auth, an open-source identity and delegation layer for autonomous AI agents, providing scoped, time-bound credentials, per-tool authorization, and audit trails for cross-agent trust in multi-agent systems.
Research Engineer — Ethereum Protocols & P2P Networking, Status (Jun 2025 – Present)
- Authored the RFC and shipped a Go-based PoC for Logos Capability Discovery — a novel Disc-NG protocol built on libp2p Kademlia DHT — significantly reducing peer discovery time for smaller services.
- Maintain nim-libp2p: designed and shipped automated integration tests for Logos Capability Discovery, and reviewed/landed critical PRs across the core service-discovery protocol implementation in production.
- Ran nodes and validated discovery flows for Logos Delivery in a live network, characterizing behavior. (Article)
- Built a Go-based discv5 crawler that discovers, processes, and logs active Ethereum mainnet node IDs.
Research Engineer — Ethereum Protocols, Status (Jul 2024 – May 2025)
- Built the BlobTx Suffix Miner in Go, retrieving post-EIP-4844 blob transactions from mainnet and performing suffix mining by modifying GasTipCap to generate all 16 possible 4-bit hash endings for downstream research.
- Analyzed 295K Type 3 transactions across 7K post-Pectra epochs from 85 unique senders via a custom Go-based mainnet crawler, publishing the resulting blob-activity patterns and trends on ethresear.ch. (Article)
- Simulated vertical block dissemination across 10,000+ nodes under realistic latency models, demonstrating reduced propagation time versus traditional block-builder broadcast for post-Pectra scaling.
Software Engineer Intern — AI & Full Stack, Netradyne (Jan 2025 – Jul 2025)
- Engineered an end-to-end RAG pipeline with containerized ingestion, object storage, PGVector on PostgreSQL, and an LLM endpoint, powering an interactive semantic-document chatbot with real-time queries.
- Shipped production features across AngularJS + Spring Boot services supporting 3,000+ enterprise clients, with REST APIs backed by PostgreSQL, automated integration testing, and CI/CD pipelines via Jenkins.
Research Engineering Intern — Ethereum Protocols, Status (Jan 2024 – Jun 2024)
- Built a Python simulator for Data Availability Sampling (DAS) on a 10,000+-node network, modeling malicious peers, gossip protocols, and correlated failures for Ethereum Layer 1 scaling research.
- Evaluated data availability under Byzantine attacks and adaptive adversaries via sampling techniques, improving retrieval latency, bandwidth, and reconstruction; analyzed with Pandas, NumPy, and Matplotlib.
LFX Mentee — AI & Open Source Program Management, Hyperledger Foundation (Jun 2023 – Nov 2023)
- Embedded with 13 Hyperledger project teams as technical lead for the Documentation Task Force, diagnosing workflow gaps, standardizing tooling, and shipping improvements coordinated across 6 sub-committees.
- Founded the AI Task Force, scoping requirements with cross-functional stakeholders, evaluating LLM tooling, and deploying AI workflows that automated repetitive tasks and measurably improved contributor productivity.
MLH Software Engineering Fellow — DeFi, Solana Labs (Sep 2022 – Dec 2022)
- Built pyzeta, an open-source Python SDK for Zeta, a Solana-based decentralized derivatives exchange.
- Integrated SPL Token Program and AnchorPy for wallet management, transaction signing, and order settlement.
