Summary
👤
Senior🎓
Top SchoolJoshua Parkin is a Co-Founder and full-stack engineer with a decade of experience building distributed systems, agentic AI flows, and real-time GPU-powered media pipelines. He combines deep expertise in decentralized web tech—Holochain, ADAM/AD4M, IPFS—and practical production engineering, having architected low-latency cloud GPU inference for avatar streaming and scaled lip-sync systems to tens of thousands of sessions. His background spans backend Rust and Python services, graph databases and semantic ontologies, with notable open-source contributions to Holochain core indexing and a public GitHub portfolio. Joshua has repeatedly turned research-grade ideas (reputation-aware search, DID-based identity, LLM context agents) into shipping products and tooling that emphasize user-centric, interoperable architectures. Based in Bristol, he blends systems-level thinking with product delivery, and often surfaces non-obvious gains by rethinking where logic lives—at the agent, not just the server.
