During March 2026, Fran Ivan developed the Obsidian Vault Import feature for the toeverything/AFFiNE repository, enabling seamless migration of notes, images, and assets from Obsidian into AFFiNE. He engineered a two-pass import process in JavaScript and TypeScript to resolve Obsidian wikilinks, preserving cross-document references and minimizing manual fixes. His work included robust handling of emoji and metadata, syntax conversion, and a dedicated UI flow for vault selection. Fran also addressed a core mutation bug affecting import reliability and implemented end-to-end tests to validate asset handling and link integrity, demonstrating depth in Node, React, and full stack development.
