I build blockchain systems that run in production — Solidity smart contracts, Hyperledger Fabric networks, and the backend architecture connecting them to real transaction volume. If you're scoping a blockchain product or need an architect to take ownership of a specific piece of the stack, that's where I fit. Most of my work falls into five areas: - Solidity and EVM smart contracts — token standards, staking and vesting logic, DeFi trading, and Chainlink oracle integrations, built with Hardhat and OpenZeppelin - Hyperledger Fabric and private blockchain infrastructure — chaincode development, channel and MSP configuration, automated network deployment - Backend architecture for blockchain products — Node.js and Go services, PostgreSQL data layers, REST and WebSocket APIs - Fireblocks and MPC custody integrations for fintech and payment platforms - AWS, Docker and Kubernetes for deploying and scaling all of the above A few examples of what that's looked like in practice: I built a self-service platform that provisions fully configured Hyperledger Fabric networks on AWS EKS, cutting deployment time from three days to under twenty minutes. I was sole architect on a cross-border payment system settling transactions across three currencies in under two seconds, using Fireblocks for custody and a PostgreSQL ledger built for AML/KYC audit trails. I've also led teams building an EVM-compatible Layer-1 chain from scratch and a full NFT marketplace from contract through frontend. For projects that need more than backend and contracts — a React/Web3 frontend, Unity for blockchain gaming, or design work — I lead a senior team directly, so the architecture stays consistent as the scope grows. If you're working through a specific architecture decision, evaluating your current stack, or scoping a new build, tell me where things stand and I'll give you a straight answer on what it'll take.
