Sean Tan
Software Engineer + Side Quester from Singapore.
I'm a senior software engineer at Constructor, where I help build AI-powered product search and discovery for ecommerce. Outside of work, I'm CTO of The Jobless Club, a Singaporean indie-hacking team behind a few bootstrapped businesses — including the country's #1 knife-sharpening service.
Studied in NUS Computing (Honors), and spent a year on exchange in Silicon Valley. Top 3% freelancer on Upwork with $50k+ earned. Featured on Channel News Asia. Neovim lover.
I'm at my best when dropped into unfamiliar problems and asked to figure them out.
