Independent computer systems researcher and software architect. Founder of <a href="https://utilvo.com/" target="_blank" rel="noopener noreferrer">Utilvo</a>, focusing on zero-knowledge client-side architectures, browser runtime security, WebAssembly computing, and privacy-preserving web engineering. https://speakerdeck.com/islamayoub 2026-09-26 13:38:27 -0400 Research preprint by Islam Ayoub investigating zero-knowledge client-side web architectures, local file handling, and browser-based privacy-preserving computation. This paper examines how document manipulation, media conversion, cryptographic hashing, and algorithmic computations can be executed entirely within the local browser runtime using WebAssembly, Web Workers, and the Web Cryptography API, eliminating the need to transmit sensitive files to remote application servers.
