Node operations
I work across execution and consensus clients, handling upgrades, forks, incidents, and the coordination that network changes require.

OVERVIEW 03 / BLOCKCHAIN & DATA
From operating nodes to making chain data usable.
At Pinax, I work with the infrastructure behind multi-network blockchain data services. My experience covers consensus and execution clients, RPC, Firehose, Substreams, and network upgrades. Earlier roles add smart-contract security and Hyperledger Fabric development. I also build public tools that make network metadata and RPC workflows easier to use.
THE ENGINEERING SCOPE
What I work on.
Practical capabilities, grounded in professional work and the projects below.
SYSTEMS VIEW01 — 04
Blockchain & Data: Connected through hands-on engineering.CONCEPTUAL ILLUSTRATION
Blockchain data pipelines
I operate services that expose chain data through RPC and streaming interfaces, including Firehose and Substreams for The Graph ecosystem.
Developer tooling
I build network registry and RPC tools, connecting chain metadata, endpoint health, and interfaces for developers and AI assistants.
Contracts & deployments
My blockchain work also includes source and attack-surface analysis, enterprise ledger development, and NFT deployment projects.
PROFESSIONAL EXPERIENCE
The work behind the knowledge.
The parts of my career most relevant to blockchain & data.
Site Reliability Engineer
- I operate multi-network blockchain infrastructure across execution clients including Geth, Nethermind, Besu, and Reth, and consensus clients including Lighthouse, Prysm, and Teku.
- I work with RPC, Firehose, Token API, and Substreams services, including upgrades, forks, incident response, and community coordination.
Blockchain Security Analyst
- I examined attack surfaces across validators, minting, bridges, and smart contracts, and validated reported exploit proofs of concept.
- I developed Bash checks and security guidance for validator operations and worked with monitoring and post-incident analysis.
Engineer, Blockchain
- I developed Hyperledger Fabric applications with React, Node.js, and SQL, working within an agile delivery process using Jira and Bitbucket.
