Creator & Chief Bug Slayer

Thien is the founder of iotools.cloud and the engineer behind its catalog of free, browser-based utilities. He builds heavily with AI — using it to draft, iterate and ship fast — but nothing goes live on vibes: every tool is tested against real inputs and reviewed by him for correctness, speed and privacy before it ships. He's spent over a decade building web products and developer tooling, which is exactly the experience that tells him when an AI-written tool is actually right versus just plausible-looking.
