Top SchoolMichael H is a versatile full-stack engineer based in Seattle with nine years of experience building high-throughput, consumer-facing web3 services and wallets. He has shipped backend and frontend systems at scale for products handling millions of monthly active users, including contributions to the widely used MetaMask extension and production services at Consensys and MyCrypto. Technically fluent in TypeScript, Golang, SQL, Terraform and AWS, he focuses on observability, latency optimization, caching and cost-efficient architectures that measurably improved performance and reduced costs. He’s led small engineering teams, driven documentation and design efforts, and introduced Prometheus/Grafana observability patterns across multiple services. An Ethereum, IPFS and privacy enthusiast, he blends open-source contributions with production security experience supporting high-value crypto transactions. He’s as comfortable tweaking a phishing-detection UI in a popular browser extension as he is architecting multi-database query services for 30M+ MAU products.
