Summary
🤩
Rockstar🎓
Top SchoolAndrew C is a software engineer based in Boston with four years of experience building developer-facing infrastructure and production systems, currently improving financial services at Series B startup OnePay. He has deep hands-on expertise in blockchain tooling from his work at Algorand—contributing to core Go runtime changes, SDKs across JavaScript and Python, ABI support, and test automation for one of the leading public blockchains. Prior roles include building no-code industrial apps and developer efficiency improvements at Tulip, and internships at Google and Amazon where he shipped networking and distributed tooling. Comfortable across languages (Go, Python, TypeScript, Java) and CI/container tooling, he blends compiler and systems knowledge with practical product delivery. Uncommonly for his experience level, he has shipped changes that affect VM opcodes and smart-contract ABI encoding, reflecting a mix of low-level protocol design and high-level SDK ergonomics.
