Rockstar🎓
Top SchoolHannah Howard is a seasoned CTO and senior developer with 13 years of experience building and leading teams to deliver distributed systems, Web3 infrastructure, and front-end applications from Los Angeles. She has deep hands-on expertise in Go and JavaScript ecosystems, contributing to high-profile open-source projects like IPFS/kubo, Filecoin (Lotus and Venus) and Angular, where her work spans core protocol features, data transfer/graphsync implementations, and nuanced front-end integrations. As a leader at Protocol Labs she led retrieval client work and GTM for Web3 storage and CDN products, and at Carbon Five she was a technical anchor across diverse stacks—demonstrating an unusual ability to move between low-level networking and polished user-facing code. Hannah also has a history of teaching and mentoring, from classroom instruction to leading 10-person client teams, and she brings an operator’s pragmatism from roles as an IT director and startup consultant. Notably, her contributions include refactors and tests that improved system robustness for peer-to-peer data retrieval—work that quietly underpins decentralized storage used by many projects.
