Rockstar🎓
Top SchoolEd Mack is an owner and principal software engineer with a decade of focused experience building backend systems, blockchain clients, and bespoke software for small businesses out of Buffalo, NY. He blends hands-on engineering with client-facing product discovery at his studio, turning messy workflows into mobile and web apps, integrations, and automation that reduce manual work. Prior to founding Bespoke Byte Builders he spent six years contributing to prominent open-source blockchain projects—helping implement Ethereum Classic hard-fork support in Hyperledger Besu and adding core Polkadot host features in ChainSafe’s Gossamer—demonstrating deep expertise in EVM semantics, gas calculations, SCALE encoding, and RPC mechanics. His background includes long-term enterprise application work and an early career in quality assurance, giving him a practical, process-oriented approach to reliable production systems. He holds a BA in Computer Science from the University at Buffalo and pairs entrepreneurial drive with low-level protocol knowledge that few small-studio founders possess.
