Summary
🤩
Rockstar🎓
Top SchoolIan Preston is a Senior Software Architect based in Oxford with 15 years of experience building distributed systems, virtual machines, and backend services—primarily in Java and pure JavaScript. He combines deep systems-level knowledge (including x86 machine code and VM implementation) with practical backend and DevOps contributions to notable open-source projects such as IPFS Kubo and the Java IPFS HTTP client. His work on Peergos highlights expertise in secure, peer-to-peer storage and social protocols, while contributions to IPFS show a knack for robust proxy and stream handling in production-grade networks. A strong tester and architect, he routinely refactors for performance and adds comprehensive test coverage, reflecting an engineer who values correctness as much as scalability. Outside of engineering, he pursues interests in physics, algebra, topology and cryptography, which inform his careful, research-minded approach to hard systems problems.
