Summary
👤
Senior🎓
Top SchoolHongchao Liu is a seasoned software engineer with 12 years in production software and seven years focused on blockchain, currently a core contributor to Alephium, the first live sharded layer-1 improving on Bitcoin fundamentals. He combines deep systems expertise in Scala, Erlang, and C with hands-on experience across full-stack Web2, GCP, DevOps, payments, and distributed databases/queues, and has held technical leadership roles coordinating cross-team engineering practices. Hongchao is pragmatic about decentralised design—he built a Bitcoin Script learning tool (nioctib.tech) and blogs about technical trade-offs at hongchao.me—demonstrating both an educator’s mindset and a taste for abstract ideas (as his GitHub bio hints). Having worked in startups and large organisations from Klarna to IBM, he blends research-driven R&D with production-grade delivery, particularly around performant, energy-efficient blockchain platforms.
