Matt Brassey
Engineering Manager, Staking — Blockchain Infrastructure Architect
Commanding 50+ validators across 25+ protocols with $500M+ AUM. Building the decentralized future from bare-metal to smart contracts.
Engineering Manager of Staking at Blueprint, a Hivemind Capital venture. I operate profitable validator fleets across Solana, Ethereum, Avalanche, Algorand, Audius, and Canton — 50+ nodes with $500M+ AUM on hybrid bare-metal and cloud infrastructure I built from the ground up. I designed a unified blockchain gateway aggregating live and historical data across 25+ protocols through a custom OpenAPI specification, and built the deploy, upgrade, and resync primitives that power AI-driven validator operations.
Infrastructure Command
Real-time validator and node operations across multiple blockchain networks. Deploying, monitoring, upgrading & maintaining profitable mainnet validators and data RPC nodes.
Solana Firedancer Validator
High-performance bare-metal validator running Firedancer client. AMD EPYC 9654 (96 cores, 192 threads), 768GB DDR5, dual 3.84TB NVMe, 10Gbps dedicated.
Ethereum Whale Validators
Two enterprise-grade beacon chain validators with MEV boost. Running Besu execution client and Teku consensus/validator client.
Avalanche Validators
Fleet of 8 Avalanche validators under infrastructure contract with Hivemind Capital Partners. Operating and maintaining all validators that the AVAX One treasury stakes to for rewards. Supporting 13.9M+ AVAX holdings.
Audius Validators
17-node validator fleet supporting the decentralized music platform. Hosting media content and earning 13,000+ AUDIO tokens weekly.
Algorand Participation Nodes
Four participation nodes contributing to Algorand's Pure Proof-of-Stake consensus mechanism and network security.
Canton Validator
Canton Network validator supporting the enterprise-grade blockchain for synchronized financial markets.
The 1000x Developer
16 years of battle-tested engineering provides the wisdom and architectural judgment that transforms AI from a tool into a force multiplier. As an elite AI operator and cutting-edge technology adopter, I combine deep infrastructure expertise with 1000x development velocity — the experience to know what to build, and the AI mastery to ship it in days instead of months.
Claude Code & OpenClaw
As operator and commander of elite AI agent fleets, I orchestrate specialized agents across every layer of the application stack — from infrastructure provisioning and smart contract development to frontend engineering, API design, and automated testing. I design custom OpenAPI 3.1 specifications and build MCP servers from scratch — CC Ledger exposes 15 MCP tools for Canton blockchain operations, and Solentic provides 26 MCP tools with an A2A agent card for autonomous Solana staking. Each agent brings deep domain expertise; I provide the architectural vision, quality standards, and integration strategy that transforms raw AI capability into production-ready systems shipping at institutional scale.
Wisdom + Velocity = Elite Operator
16 years of extreme DevOps and engineering — from founding a solar-powered hosting company and managing 900+ servers at IBM, to maintaining 200+ wallet infrastructure at Bittrex, to running $500M+ in validator infrastructure — provides the hard-won wisdom and guidance that separates an elite AI operator from someone just prompting. Combined with 5+ years of blockchain-focused development and relentless adoption of cutting-edge tooling, every AI-generated artifact is vetted against production-grade standards born from real-world failures and victories. Experience is the compass; AI is the engine.
Experience
16+ years of engineering — from founding a hosting company to managing $500M+ in blockchain infrastructure.
