• ◇Shipped an AI assistant with retrieval over a vector knowledge base, plus AI resume and cover letter tools, with per-user quotas and provider fallback

• ◇Fixed a race where out-of-order saves wiped user edits, by serializing writes through one promise chain
• ◇Shipped the app in 7 languages, including right-to-left Arabic, across 120+ reviewed pull requests
