Available to hire
I’m Allan Park, a software engineer with decades of experience spanning security, distributed systems, embedded software, and blockchain. I’ve built systems from low-level drivers to scalable cloud services, always prioritizing security, performance, and reliability.
Recently I’ve worked on secure messaging ecosystems, cross-chain Oracle tech, and tokenization platforms, while contributing to standards (MLS RFC 9420) and leading multi-platform implementations. I enjoy solving hard problems at the intersection of cryptography, systems programming, and product engineering.
